Other connection may not see updated date immediately

[W]

Hi,I have a web application. It is a java-jsp-tomcat-mysql. It is working, but 
sometimes, it is slow. For each data update statement, it is not slow: the next 
jsp page shows promptly. But the next page does not see updated data. I wait a 
coupe seconds, refresh the page, the updated date shows. Each connection is 
from tomcat.DataSource, so I believe each jsp page may use a different database 
connection. So, mysql inside is slow. Anything I can do?
I checked server cpu and memory. Cpu is 20%, memory is lower than 50%.
Everything is running on one server machine, one tomcat, one mysql, runs on 
Ubuntu: 4.15.0-54-generic, Tomcat/9.0.16, mysql: 8.0.21.
Any information would be appreciated. Thanks in advance.

The query is commited, otherwise I would not see updated data after I refresh

I believe, correct me if I am wrong:tomcat.connection.commit() calls 
mysql.connection.commit(), Is it possible thatactually 
operating-system-file-writing not finished when the calls return? or there is a 
delay, or updating query haslower priority, either tomcat or mysql? The 
following connectioncall is a 'select' statement without delay, so 'select' 
statement executed before operating-system-file-writing finished.
It sounds that you did not hear similar issues.
Thanks.

Tomcat 9 can not start on windows 10 as service

[W]

Hi,
I install tomcat 9 using downloaded installation package. It was installed 
successfully. I made tomcat manager working. I deployed my application... 
Suddenly, tomcat stopped. Then I try to restart it using windows service. I got 
error 5: access denied. I uninstalled tomcat and re-installed it. The same 
thing happened. 
Now I can go to tomcat\bin directory run startup.bat. It works.
What is wrong? How can I run it automatically using windows service? Please.
Any information would be appreciated. Thanks in advance.

Re: Tomcat 9 can not start on windows 10 as service

[W]

 Thank Bill, I downloaded it and run it successfully. But when I modified 
confg/tomcat-users.xml (so I can use manager), Tomcat service stopped. Status 
became disabled. When I tried to restart the service, it told me that the 
service was marked for deletion. So I uninstalled tomcat by using "Add or 
remove program". It went through. But tomcat service is still in Service window 
and I can not remove it.
How to remove it please?Thanks.

For Windows users, I provided an alternative installer that might work
better for you:

https://github.com/Bill-Stewart/ApacheTomcatSetup

It provides a means for specifying which account you want to use to run the
Tomcat service (running as local system is definitely not recommended), and
it also sets file system permissions appropriately.

You need to provide filters to the program in order not getting lost in all the

Hi W,

Kindly check which user is setup to run the Tomcat Service and make sure that 
that user has at least read/execute permissions to your CATALINA_HOME and 
CATALINA_BASE directory structures. (Note, this may be the same location 
depending on how you have configured Tomcat.) More than likely it's the Local 
System account.

You will want to make sure that at least the webapps, work, temp, and logs 
directory have Modify permissions at a minimum for that user.

Hope this helps,

The tomcat9 package on Debian/Ubuntu uses systemd and leverages its
sandboxing feature to limit the write access to the conf, log, work and
webapps directories by default. If you look at the package's README file
(/usr/share/doc/tomcat9/README.Debian) you'll find the instructions to
grant Tomcat write access to other directories:

https://salsa.debian.org/java-team/tomcat9/blob/master/debian/README.Debian

  If write access to other directories is required the service settings
  have to be overridden. This is done by creating an override.conf file
  in /etc/systemd/system/tomcat9.service.d/ containing:

    [Service]
    ReadWritePaths=/path/to/the/directory/

  The service has to be restarted afterward with:

    systemctl daemon-reload
    systemctl restart tomcat9

The document you pointed is very good. It solved my problem. 
For the people who are facing similar issues, I would like to tell my

not improve much (maybe my app is small). Then I tried entropy. It 
significantly improved. Problem solved.

It isn't guaranteed to work in all circumstances but try:

ServletContext.getRealPath("/")

If that doesn't work then - assuming you can use reflection - something
along these lines:

Obtain the ServletConext.
Cast it to org.apache.catalina.core.ApplicationContext

Use reflection to read the context field or call getContext() which will
return a StandardContext instance.

Then you have various options:
- call getDocbase()
- call getPath() and getWebappVersion()

and there are probably plenty of other similar approaches that would work.

Please note that there is a regression in 9.0.96 that you need to be

aware of that affects JSPs. It will affect you, since you are reporting

(a) missing method errors and (b) you want to clear your work directory,

presumably to remove .jsp -> .java -> .class files to trigger

recompilation of all of those.



I would pause and NOT deploy 9.0.96 because recompilation will stop the

app from throwing those missing-method errors, but some tags might

actually not behave properly.

As to your question about procrun running a script before it launches

Tomcat, I think the short answer is "no" but I do have an idea for you.



Create a new service called Tomcat-cleanup, make it a simply BAT/PS

script that cleans-out that directory, and make it a startup dependency

of the real Tomcat service.



-chris





You can also create a scheduled task that starts every time a Windows service 
starts and this task could run your script for you.
this script would require possibly administrator rights in order to actually 
perform any file operations that your script would need to do, but this is your 
call and it wouldn’t compromise the tomcat service or service account so could 
be an alternative.

Tomcat on Windows : new keystore possibilities

[david w]

Hello
Referring to the documentation on Apache Tomcat 9 Configuration Reference 
(9.0.87) - The HTTP 
Connector
 keystore types, i wanted to get mentioned that a new set of possibilities is 
available with newer java builds, when using Tomcat in a Windows environment.


As mentioned on the OpenJDK bug tracker: 
https://bugs.openjdk.org/browse/JDK-8286790


The Windows KeyStore support in the SunMSCAPI provider has been expanded to 
include access to the local machine location. The new keystore types are:



Windows-MY-LOCALMACHINE

Windows-ROOT-LOCALMACHINE



The following keystore types were also added, allowing developers to make it 
clear they map to the current user:

 Windows-MY-CURRENTUSER (same as "Windows-MY")

Windows-ROOT-CURRENTUSER (same as "Windows-ROOT")


Alongside other configurations possible on the server side, web certificates 
can be automatically published, renewed and managed with a company's internal 
Active Directory CA. The account running the Tomcat Windows Service needs local 
Administrator rights to be able to refernce these certificate stores.

With this enabled, and setting the server.xml Connector like shown below can 
make certificate management a lot easier.



the use of a predefined Environment Variable for the system name, possible when 
using also this setting  in catalina.properties:
#GPO Managed restricted file: TESTING
#allow_System ENVVar Usage
org.apache.tomcat.util.digester.PROPERTY_SOURCE=org.apache.tomcat.util.digester.Digester$EnvironmentPropertySource

 makes it easier to maintain a common server.xml file through tools like GPO.

Could it be useful to somehow document this, as it does make our WIndows admin 
life easier!!

Fortunately, this statement is not correct.

I would definitely not recommend running the Tomcat service using a
privileged account.

I understand, but am not looking for troubleshooting but trying to raise

I'm not sure what's different on your system or why you think a privileged
account is required.

In any case, this would not be a Tomcat-specific issue but rather some kind
of configuration issue. (What I am saying is that troubleshooting this
issue on your machine is really outside the scope of this specific mailing

I would repeat my recommendation not to run a web server of any kind
(Tomcat or otherwise) using a privileged account.

Re: How to configure Tomcat with a Managed Service Account when using LocalMachine certificates for TLS

[david w]

I've had the same experience, but with a regular AD service account, not an MSA.
The account needs to have local administrator rights for the certificate to be 
found and used; setting ACL on the keystores is not enough.

A few questions:

- how are are starting Tomcat?

- is Tomcat installed as a Windows service?

- which account is Tomcat running under?

There are a few references to "user" in your question. It is not clear
if this is:
- the user administering a Tomcat service
- a user that is starting Tomcat from the command line
- the user that the Tomcat service is running as
- something else

(Tomcat v 11.0.0, java v 22.0.2)

Hi,

System.out.println(..) works just after tomcat startup to
catalina.out. But at some point later on, souts fail to be logged to
catalina.out or anywhere. I am also experiencing something weird with
File.mkdirs(..); I have it in two different static functions in a
utility class, but it only works in one of them (I would give you some
sort of exception, but it seems exceptions arent logged to
catalina.out either, after the same point where sout stops working).

I will note that *sometimes* I get the following SEVEREs in
catalina.out on tomcat startup/deploy of my webapp:

SEVERE [Catalina-utility-2]
org.apache.catalina.startup.ContextConfig.beforeStart Exception fixing
docBase for context [] - java.util.zip.ZipException: zip END header
not found
SEVERE [Catalina-utility-2]
org.apache.catalina.startup.HostConfig.deployWAR Error deploying web
application archive
[/home/user/apache-tomcat-11.0.0-M24/webapps/ROOT.war] -
java.lang.IllegalStateException: Error starting child

(I am using maven with the build plugin maven-war-plugin to build the
war; this is the only maven build plugin I have) but otherwise, my
webapp runs smooth.

Any obvious potential causes?

Thanks

How to measure queueing time: from tomcat recieving request to axis web service

[Pim W.]

Hi,

I want to measure the queueing time starting from when Tomcat recieve the
request from a client until the request reach my process.
I am writing a web service application hosted under axis engine.
I want to
- Get the time stamp when the request arrive at Tomcat

And I then want to find the distance between the timestamp when Tomcat
recieves the request and the time stamp when my web service starts working.
But I dont know where or how should I modify tomcat to get the time stamp
when the request comes.
I tried to read the architecture of Tomcat but I dont really understand
where the request arrives.

I'm not sure if I should post this in user mailing list or developer mailing
list.
Can somebody please point me the way?

Hiding JSP Pages

[W Strater]

I am trying to hide the JSP so they can only be accessed via a forward. I have 
been able to put them in a subdirectory of WEB-INF using other containers but 
have not been able to do that with Tomcat 5.5.

We are not using Struts but it is the same approach where our business
logic is servlet/action based and we only use JSP for presentation.

A common practice would be to put the JSP page in the root directory of the WAR 
like following:

/HelloWorld.jsp
/WEB-INF/web.xml
/WEB-INF/classes/HelloWorld.class

This would allow the user to access the JSP page through the servlet with 
http://localhost:8080/app/HelloWorld or directly with 
http://localhost:8080/app/HelloWorld.jsp.

I want to use to only be able to access the JSP page through the servlet and 
the directory of the WAR would like the following:

/WEB-INF/web.xml
/WEB-INF/classes/HelloWorld.class
/WEB-INF/jsp/HelloWorld.jsp

The HelloWorld servlet would use the JSP for presentation by forwarding to it 
using code like the fllowing:

RequestDispatcher dispatcher = request.getRequestDispatcher("
/WEB-INF/jsp/HelloWorld.jsp");

I get the following errors:

Most of the discussions I have read are either old or pertaining to securing 
them via authentication/authorization but I do not want a user to be able to 
enter a URL containing a JSP page under any conditions. 

Any suggestions on how I can hide my JSP pages? 

Thanks,
Wes.

Virtual Hosts or Multiple Instances

[D W]

Hi all,

I run multiple servers, and have experimented with both virtual hosting
within in a single server.xml and CATALINA, and have also tried setting up
separate Tomcat instances each with their own CATALINA_BASE.

Both have worked in my experiments.

Does anybody have an opinion as to which approach is better?

Resource-wise?

Management-wise?

I can see pros and cons to both, but am curious what veterans think.

Thanks,
DW

Invoker Not Invoking in 5.5.9

[W Strater]

I know that the servlet invoker is not popular but that is what I have to deal 
with.

All of the servlets are invoked as 
http://localhost:8080/servlets/com.domain.servlets.ServletName where the 
/servlets is the web app name.

I would like to acheive to things.

1) Ensure that only servlets within a package get invoked.
2) Provide a catch all servlet.

Here are my servlet mappings:




invoker

/com.domain.servlets.*









catchAll

/*






The problem is that the catchAll is getting every request despite being defined 
after the invoker. I have even defined a new servlet name, , with the 
invoker class, org.apache.catalina.servlets.InvokerServlet, still the catchAll 
gets all requests.

Any suggestions?


Wes.

Single WAR to update multiple contexts

[Sean W]

Greetings!

I have a single war packaged application that needs to have about 200 unique
context paths running (200 copies of the application running - each uses a
different database based on the context name).

I know how to deploy 1 context at a time, but how can I do this so that if I
want to update all these contexts to the "next version", I can update them
all at the same time easily?

Any suggests are much appreciated. Thanks!
-Sean W

Re: Single WAR to update multiple contexts

[Sean W]

Using a single webapp sounds like a nice idea, and hopefully feasible, I will
look into this more since I think that solution would be the most efficient.
However, the reason why this would be difficult is:

I am using Apache Wicket's WicketServlet, which is mapped to a single Wicket
Application class. The Application class initializes many in-memory
variables that depend on which database it is initialized with. Recall the
database loaded depends on the context name.

I could try to create multiple WicketServlets within a single web-app, but I
rather avoid hard-coding the "list of 200 sites" into the WAR. Ideally using
the 1 web-app method I'd like to create a filter that will make:

"/ctx1/wicket/homepage" construct the wicket application using a config file
called ctx1 and 
"/ctx2/wicket/homepage" construct the wicket application using a config file
called ctx2 (if it exists) etc...

That way I'd only have to add/remove config files that contain database
connection info to add/remove "sites".

I will try to see if I can bend the functionality of WicketServlet to do
this. I'm not sure I can easily. Thanks!

Is it possible to delay HTTP port opening?

[Jesper W]

At server startup, is it possible to configure tomcat to not open it's 
http ports so early?


By default the server starts to receive http requests quite long before 
initialization is complete. These requests are held open until the 
server is ready to respond, and then the response is sent.


In my case this behavior is not desirable, I would like the server to be 
fully ready and warmed up before the http port is actually opened for 
requests.


The reason is the server is part of a load balanced pool, and if the 
load balancer detects a just-started server too early, users will 
experience unacceptably long response times.


Cheers,
/j

No mater when you initialize the http port there will be always
some potential initial startup period depending on you application,
so this is completely useless.
Thanks for your kind words. However I would consider improving the 
situation totally useful, even if it doesn't solve it to 100.0%.

And for what it's worth, allowLinking appears to have fixed it :)

It manifested itself really silently and I didn't see anything about it in
WebAppClassLoader.java so it never occurred to me it was possibly
configurable. Now I can see the DirContext object that's used in there and
everything makes sense.

we did find a msvcrt.dll which didn't do the trick.)

Any pointers would be great!

We're not having any problem with "Internal Error 2318.

There are some interesting steps here but not sure how they apply to
our situation. (Probably just me being dense, of course.)

We can't use 1.6 -- the system we're installing is only confirmed to
work on Java v1.5

We've got the JDK and JRE from the same installer
(jdk-1_5_0_18-windows-amd64.exe) so in theory they should be
compatible, no?

startup.bat and catalina.bat -> NoClassDefFoundError: server

[w...@serensoft.com]

First, I appreciate your responses and your help. Thanks! Here's my
new question:


Short version:
We find what the launch-tomcat command is from the startup.bat and
catalina.bat files, and paste that in directly at the command line,
only to get:
"Exception in thread "main" java.lang.NoClassDefFoundError: server"

It it naive to think this is our problem? (E.g. the batch file may be
setting other variables...) Ideas?


Long version:

Okay, so we're trying to get Tomcat to run under 64-bit Windows 2003
Enterprise... Java is fine, but tomcat won't even begin to start.
Blip, the console window shows up and instantly goes away again, no
files open, no ports open, no tomcat/java process at all.

When we "rem" the "@echo off" statements in the Tomcat batch files to
see what's going on, we can see that the final command to execute
tomcat is:

start "Tomcat" "C:\Java\jdk1.5.0_18\bin\java" server -Xms768m -Xmx768m
-XX:PermSize=128m -XX:MaxPermSize=256m -XX:NewSize=192m
-XX:MaxNewSize=384m -XX:+UseParallelGC
-Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager
-Djava.util.logging.config.file="C:\Tomcat55\conf\logging.properties"
 -Djava.endorsed.dirs="C:\Tomcat55\common\endorsed" -classpath
"C:\Java\jdk1.5.0_18\lib\tools.jar;C:\Tomcat55\bin\bootstrap.jar"
-Dcatalina.base="C:\Tomcat55" -Dcatalina.home="C:\Tomcat55"
-Djava.io.tmpdir="C:\Tomcat55\temp"
org.apache.catalina.startup.Bootstrap  start

Meaning that we're just basically calling java, with the tomcat
bootstrap.jar of course. So we try pasting that command (without the
'start "[arg]"') and we get:
Exception in thread "main" java.lang.NoClassDefFoundError: server

Is this error misleading? Bootstrap.jar is indeed where it's expected...

Is there something else in the batch file that would set up a more
reasonable environment so that the 'server' class would be found? If
not, is there something obvious here that we've missed in order to get
tomcat off the ground?


C:\Tomcat55>java -version
java version "1.5.0_18"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_18-b02)
Java HotSpot(TM) 64-Bit Server VM (build 1.5.0_18-b02, mixed mode)

Java runs hello-world just fine.


Ancillary question:

tomcat connector, tomcat native, and 64-bit windows

tomcat.apache.org offers a ZIP download of tomcat, plus a "tomcat
connector" and a "tomcat native". There's documentation for each, but
the intended audience seems to be folks who already know what each of
those is for.

What would the "tomcat connector" be for, or what's the "native"
instance all about. At tomcat.apache.org there are 64-bit downloads in
those categories, but how do they relate to the normal ZIP downloads?

running tomcat5 -- as a service under 64-bit windows?

[w...@serensoft.com]

Hi folks --

Short version: how to get Tomcat5 to run as a service under 64-bit Windows 2003?

Long version:

Okay, we've got Tomcat5 running from the command-line within 64-bit
Windows 2003 Enterprise (and cannot use tomcat 6/java 6 for our
project) -- and now we're working to get it running as a service...

We've replaced the original tomcat5.exe and tomcat5w.exe with the ones at
http://svn.apache.org/viewvc/tomcat/connectors/trunk/procrun/bin/amd64/
as directed from
http://www.nabble.com/running-tomcat-5.5-as-a-service-on-64bit-windows-td6821449.html

And then command line 'service install' appears to work (it shows up
in admin tools > services) but the service won't start: it tries for a
while (netstat -nab shows it's running for a spell), but it quietly
gives up. tomcat/logs/stderr* does contain some text, but there's no
catalina.out, and start > admin tools > component services > events
doesn't give up any evidence either.

Plus, the mofidied/64-bit-savvy tomcat5w.exe which is supposed to set
parameters for the service, complains that 'tomcat5' doesn't exist.

Ideas?

We just got Tomcat 5 to work as a service on windows 64-bit, woo hoo!
(see email with subject "running tomcat5 -- as a service under 64-bit

We thought we had another new snag, but there's just a firewall or
network issue.

We now return you to your regularly scheduled email. :)

"The Apache Tomcat service terminated with service-specific error 0 (0x0)." on Windows again... argh!

[w...@serensoft.com]

Okay -- wWe CAN start Tomcat via the command line, no problem.

But when trying to start it as a SERVICE, no luck -- we look in the
event logs and find
"The Apache Tomcat service terminated with service-specific error 0
(0x0)." again

In JAVA_OPTS we've got "-server -XX:+UseParallelGC -Xmx1200m
-XX:PermSize=120m -XX:MaxPermSize=240m -Djava.awt.headless=true" which
is what DOES work from the command line.

In the java tab via tomcat5w, where we can NOT start the service:
-Dcatalina.base=C:\tomcat55
-Dcatalina.home=C:\tomcat55
-Djava.endorsed.dirs=C:\tomcat55\common\endorsed
-Djava.io.tmpdir=C:\tomcat55\temp
-Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager
-Djava.util.logging.config.file=C:\tomcat55\conf\logging.properties
-Xmx1200m
-Xms1200m
-XX:PermSize=120m
-XX:MaxPermSize=240m
-server
-Djava.awt.headless=true

When we try to start the service we see "Invalid maximum heap size:
-Xmx1200m " in the stderr*.log output.
And the jakarta_service*.log contains
[2009-06-06 13:08:37] [395  javajni.c] [error] CreateJavaVM Failed

Migrating from GlassFish to Tomcat 7

[B W]

 I have a GWT application which currently is running on GlassFish 3.x. I
want to migrate to Tomcat 7. Previously, I would store properties that the
GWT application could retrieve by
org.apache.commons.configuration.SystemConfiguration. I would put these
settings in my domain.xml for GlassFish. What is the Tomcat equivalent? I
tried putting settings under my WEB-INF\web.xml file as
context-paramsection. However, my GWT application cannot see them
still.

Where should I put settings that can be read by calling
org.apache.commons.configuration.SystemConfiguration from my GWT app from
Tomcat?

Re: Migrating from GlassFish to Tomcat 7

[B W]

Thank you - it's working!

What is the advantage to using catalina.properties vs setenv.sh?

Class loading locking threads

[Wayne W]

Hi,

we are using a third party JAR which is about 35MB in size but is packed
with many many obfuscated classes. Due to the nature of the functionality
it loads classes all the time from the JAR file . I'm finding that will it
loads the class the other threads which want to load classes get blocked.
This is a typical stack trace:

It seems all the time is spent in the SignatureFileVerifier part - is there
any way to stop the class loader doing this and thus speed up the class
loading?

I also tried configuring the ParallelWebappClassLoader which is configured
but doesn't seem to come into play for this. I tested by doing:

conf/Catalina/localhost/test.xml:

   


and webapps/test/index.jsp:
ClassLoader: <%= this.getClass().getClassLoader().getParent() %>

which gives me (when accessed at test/index.jsp):
ClassLoader: ParallelWebappClassLoader context: test delegate: false
--> Parent Classloader: java.net.URLClassLoader@264a1535

Re: Class loading locking threads

[Wayne W]

Thanks Mark,

unfortunately its not our jar - I don't believe there is a way we can
remove the signature as all the class files are encoded.

Re: [EXTERNAL] Re: Archive localhost_access_log

[david w]

There are other ways to capture or store logs... Tools or toolsets like 
Telegraf.
OT but could be of help




Thank you Mr. Funk.

My request is two-folds a) archive the log files elsewhere (not the "logs" 
folder) based on some policy b) clean up (delete) the archived files based on 
some policy.

If I'm not mistaken, your suggestion may address the latter but nothing on the 
former?

Thanks and regards,

Personally. I rely on a daily cron with a find by time and the -delete flag. 
Where the time to keeps is based on policy.

[ANN] Java Web Parts Beta 5

[Frank W. Zammetti]

After a few months off, the Java Web Parts (JWP) team is proud to 
announce the release of beta 5!


The most notable change is that the taglib formerly known as AjaxTags is 
now known as the AjaxParts Taglib, or APT for short.  Not only is the 
name different, but the taglib has been essentially rewritten and is now 
easier and yet more powerful than ever...  If a declarative approach to 
AJAX that doesn't require you to know a bit of Javascript (unless you 
want to get into it) sounds good to you, now is a great time to check 
out what APT has to offer!


There are other additions as well, and as always, JWP provides a number 
of useful parts, such as servlets, filters, taglibs, utility classes, 
and so forth.  Things like getting the size of a session object, a 
powerful CoR implementation, filters to limit concurrent sessions, guard 
against XSS exploits and disallow app access during defined time 
windows, a class to make application configuration simple, a servlet to 
dynamically render a text of string as an image, a taglib that renders 
very handy Javascript functions, some GUI widgets... all of this can be 
found in JWP, and plenty more!


If this sounds interesting to you, have a look:

http://javawebparts.sourceforge.net

And for you Maven folks, JWP can now be found in the iBiblio repo! 
(beta4 at this point only though)


Thanks, and have a great day!

[ANNOUNCE] New article: The AjaxParts Taglib from Java Web Parts: AJAX for Java Developers the Easy (yet powerful) Way!

[Frank W. Zammetti]

Hi everyone,

I've gotten a number of requests for an article on AjaxParts Taglib, and 
I finally got around to writing it :)  You can check it out here:


http://www.omnytex.com/articles

If you have never heard of AjaxParts Taglib before, in brief, AjaxParts 
Taglib, a component of the Java Web Parts Project 
(http://javawebparts.sourceforge.net), is a taglib that allows for easy, 
declarative, event-driven AJAX, allowing a developer to add AJAX 
capabilities to existing or new webapps without the need to write ANY 
JavaScript at all!  This article demonstrates how it works, explains the 
benefits, and goes into some details about the capabilities it offers 
out-of-the-box, as well as the ways in which it can be extended to 
fulfill far more advanced users.


Hope it is helpful, and take care!

Re: [ANNOUNCE] New article: The AjaxParts Taglib from Java Web Parts: AJAX for Java Developers the Easy (yet powerful) Way!

[Frank W. Zammetti]

Thanks Michael, I appreciate you taking the time to look!

Excellent question... the answer is that the code that APT writes into 
the onClick handler for the button will append itself onto whatever is 
there already, it WILL NOT overwrite your existing code.  This wasn't 
always true, but is as of a couple of versions ago :)


FYI, if you were going where I think you might have been going... you 
can't use this to abort the request.  For instance, you might expect that...


if (!shouldAJAXRequestFire())) { return; }

...would stop the request form firing, since the APT code would follow 
this.  But, it doesn't work.  I'm actually a little surprised by that, I 
had to go try it to be sure... I guess the JS interpreter doesn't treat 
what's in onClick like a function, it's instead just a collection of 
statements that it interprets, return not aborting that interpretation.


However, it is already on our to-do list to provide this ability... we 
already have the preProc that gets called before the request, we'll 
probably examine the return from that and if false, abort the request. 
We also were thinking of adding an  child element under the  
element where you could put a Javascript snippet, and if it returns 
false, that aborts the request.  Not sure which way we'll go yet (maybe 
both)... there is a feature request on the SF site, if anyone has an 
opinion, I'd love to have it recorded :)

Re: Problem while submiting the page

[Frank W. Zammetti]

Hi,

I think you might be running into a timing issue.  I would suggest 
this... onClick of the button, first, disable the button, and then set a 
timeout, set for like 1 millisecond (which is probably a lower 
resolution than is available, but it will basically fire immediately, 
that's what you want).  Do the submission to the first action.  Then, in 
that timeout function, start another timeout for maybe 500 millisecond. 
 When it fires, make the second submission.  I'm guessing that the 
first request doesn't begin before the code starting the second one 
fires.  This timeout scheme should avoid that.


Alternatively, have another form on the page with ll the same elements, 
but hidden.  Then just have a bit of Javascript to iterate over the 
elements of the real form and transfer them to the second form.  Then 
just submit both forms, each one targeting a different action.


One other option, and probably the one I'd go for myself, is instead of 
submitting the form at all, make two AJAX requests, one to each action. 
 The submit button would be an ordinary button to avoid its own submit 
getting in the way.  It would be a little more work on your part, since 
you have to handle the response, but any of the libraries available 
today will make it childs' play.

There is a button on the screen, on click of that button i invoke the

So what happens mostly in this case is only the second action is executed. I can see the log corresponding to second action only. 


Can anyone please help me in solving this.

the code snippet in js is like this

var win = window.open("", "checklist", features);
document.formMain.target = "checklist";

Re: how to forward user to a page after container manager authntication ?

[Frank W. Zammetti]

Container-managed authentication works by intercepting a request for a 
protected (constrained) resource and redirecting to the page with the 
logon form.  Once the user authenticated, the request for the 
constrained resource continues, in effect, the user is "forwarded" to 
what they requested in the first place.  Therefore, to do what you want, 
the request that results in the logon page being shown should be for 
login_done (JSP? .do?)  Make that the default document in web.xml if 
that's what you need.

Re: Need Help w. Servlets And The JDBC.

Google is your friend... here's a quick hit:

problems with unpacking ROOT.war

[andrew . w . cooke]

Hi there,

We have been finding it difficult to persuade tomcat (5.5.12 and 5.5.17) to
unpack a ROOT.war file, either when starting up tomcat from scratch, or
hot-deploying.

We *were* able to get tomcat to expand the war file if it contains a
META-INF directory containing a context.xml file.  However if this
directory is missing from the war, and instead a ROOT.xml context file is
present in conf/Catalina/localhost before starting tomcat - the war file
*isn't* expanded.

Our server.xml file contains the default settings (unpackWARs="true"
autoDeploy="true").

Any ideas?  We would rather not include context.xml files in the war, as
the same war file will be deployed on different servers, which require
different JNDI resources.

thanks

Andy Cooke

Re: Servlet in a .jar file? AJAX access?

[Frank W. Zammetti]

Yes, certainly you can put a servlet in a JAR... after all, Struts is 
based on a servlet, and you generally just drop the Struts JAR into your 
webapp... accessing a servlet via AJAX is, in simplest terms, just a 
plain old HTTP request like any non-AJAX request, so yes, you can do 
that too.


If your servlet is in a JAR, and that JAR is in the classpath, then all 
you need to do is put the appropriate entries in web.xml and your off to 
the races... if you want to call it via AJAX, that works just fine too, 
if you just pass simple name/value pair parameters.


Does that answer your question, or did I misunderstand?

Re: problems with unpacking ROOT.war

[andrew . w . cooke]

Hi again,

OK - here are some steps you can try out to reproduce the problem I am
experiencing - I'm hoping this will tempt someone into taking a look :-).

The problem we have is that tomcat 5.5.x (I tried 5.5.12 and 5.5.17) won't
unpack ROOT.war when it is started up, if a file called ROOT.xml is present
in conf/Catalina/localhost.

(1) Build a simple webapp, for example containing:

success.html
WEB-INF/web.xml

and place these into a war file called ROOT.war.

(2) Place a ROOT.xml context file into conf/Catalina/localhost with:






The server.xml file can stick to the defaults that you get with tomcat
5.5.17 (or 5.5.12):

  

(3) Delete any directory under webapps called ROOT, and drop the war file
into webapps.

(4) Start tomcat.

--> doesn't unpack war.

(5) delete ROOT.xml from conf/Catalina/localhost, and restart tomcat

--> does unpack the war file.

Similarly, a war file containing META-INF/context.xml will be deployed, as
long as there isn't a file called ROOT.xml inside conf/Catalina/localhost.
The problem for us is that we would like to deploy the war on different
servers, offering different JNDI resources.  So shipping a war file
containing a context.xml isn't an option for us.

I have searched the mailing lists for a solution to this problem, but so
far without luck.  There was a useful mail trail last year that resulted in
a document being placed in bugzilla containing instructions on how to
deploy a root app using tomcat's manager (
http://issues.apache.org/bugzilla/show_bug.cgi?id=35063).  However our
production environments don't support the manager app.

I have tried tweaking some of the parameters.  For example, if I set a
docBase of ${CATALINA_HOME}/webapps/ROOT, I'll see a warning in the logs
saying that "a docBase [...] inside the host appBase has been specified,
and will be ignored" - which at least shows that ROOT.xml is being parsed.
Likewise, changing the the docBase to point to a directory outside of
${CATALINA_HOME} doesn't solve the problem.

(Am I right in thinking docBase *isn't* a required attribute?  If I leave
this out of ROOT.xml, and expand the war file manually, the ROOT app will
pick up JNDI resources correctly).

I've also played with some of the  attributes in server.xml, e.g.
adding deployOnStartup="true" to server.xml (it is true by default), or
setting autoDeploy="false", but none of these tweaks helped.

So - is it a bug (or a feature?!) that ROOT.war won't unpack if ROOT.xml is
already present in conf/Catalina/localhost?

Thanks for any help,

Andy Cooke

Re: problems with unpacking ROOT.war

[andrew . w . cooke]

Hi Michael,

thanks for the response.

I tried this - but no luck.  In any case, I'm pretty sure for the default
web app (ROOT), you should set a path of "":

"If you specify a context path of an empty string (""), you are defining
the default web application for this Host, which will process all requests
not assigned to other Contexts."

(from: http://tomcat.apache.org/tomcat-5.5-doc/config/context.html)

cheers,

Andy

Thanks for the feedback and the correction.  OK - I have a very simple war
file named ROOT.war - it doesn't a META-INF directory.  I have placed a
file called ROOT.xml into conf/Catalina/localhost with:

  
  
  

Server.xml has the defaults that come with tomcat 5.5.17:

  

I put ROOT.war into the webapps directory and start tomcat --> ROOT.war
isn't expanded.

Any other suggestions?  Or might this be a bug?

thanks for your help,

Neither one is correct.  You must NOT use the path attribute in a

URI path to the app is determined from the name of the .xml file in the

Re: Can a "return" statement cause a problem?

[Frank W. Zammetti]

It might be interesting to look at the class file generated from your
JSP... many times things like this become fairly obvious when you see the
code that is actually being executed.

Also, if your using a JSP 2.0 container, you may be interested in playing
with tag files:

http://today.java.net/pub/a/today/2003/11/14/tagfiles.html

Kind of a good first step for playing with custom tags without quite as
much work.

Re: disabling sessions in certain parts of a webapp

I can't think of any drawbacks to the filter, and tha's what I would have
suggested.  Although, it probably doesn't even have to be as complicated
as a wrapper... simply check for an existing session for the paths you do
want a session created for, and if none is present go ahead and create it.

That's weird... I actually had a part in my reply at the end that said
something like "this should work until some code after the filter tries to

Yep, absolutely, if there's a possibility of that then the wrapper is
definitely the way to go.

Re: advice on auto logout servlet

[Frank W. Zammetti]

You can do this strictly client-side, if requiring Javascript isn't a 
problem (which of course an AJAX-based solution does anyway).  Just 
start a timer from the onLoad event on each page.  When 20 minutes has 
elapsed, you can either pop an alert which is followed by a redirect to 
some appropriate page, or just do the redirect straight away, whatever 
you prefer.


The down-side is that a user could disable Javascript after the timer 
has begun but before the timeout occurs.  But, of course the session 
will still expire on the server, so it's probably not a big problem. 
And you'll need to keep your session timeout and client-side timeout 
values in sync, but that's pretty minor.

I did an AJAX version of this a couple of months ago.
The slight gotcha is that the AJAX request prolongs the life of the

the interval has to be slightly longer than the expiry time for the 
session.

Hi,
I would suggest that you do this by using somethinglike JSON or AJAX.
See jasonspec: http://www.crockford.com/JSON/index.html

You could make the client query your server, in some interval and check
the session state.

Re: JSP processing other than .jsp?

[Frank W. Zammetti]

FYI, I had a case once where I needed to make my CSS files JSP's because 
I was using HTC's and for some reason I couldn't get the path mappings 
to work right unless I used request.getContextPath() to prefix the HTC 
names... more than likely just my mistake somewhere, but making it a JSP 
(as Yaakov says, just renaming it to .jsp) did the trick.


I would personally prefer that approach because should you ever need to 
move to another app server, or even a hosted environment like I moved to 
a few months back, this way you won't have to mess with server settings, 
or getting some grumpy old admin to do it :)

Yaakov Chaikin wrote:

I assume you need this because you want to place some JSP code inside
your stylesheet

Two approaches:
1) If you know that ALL of your .css files will need to include JSP
code in them, then go to tomcat_dir/conf/web.xml and add another
 like so:

  jsp
   *.css


2) If you need to place JSP code in just one or two .css files, I
would not start messing with server specific configurations and just
rename those .css files to have extension of .jsp. So, now you will
have a stylesheet file with .jsp. It seems weird and unusual, but
really doesn't make any difference as far as your HTML/JSP page is
concerned. Just point the link to the .jsp page instead in your
HTML/JSP page:


Hope that helps.

JDBC/MySQL user login goes stale

[David W. Brown]

Hello TC dev and Gurus, I have a webapp comprised of several Servlets and JSP 
pages. The webapp is functioning very well but after a few hours of no 
connections or interaction the TC webapp loses its connection with the MySQL 
DB. We are using the server.xml defined JDBC/MySQL security model using the 
users and user_roles tables DB structure. The logins work perfectly until a few 
hours of (like overnight) in attendance. Even thought the TC Servlet server is 
still up and running logins all fail. After restarting TC the login mechanism 
works perfectly. Particulars follow. Please advise.

Re: making a singleton servlet

[Frank W. Zammetti]

The problem you are trying to solve is not propely solved by trying to 
limit the container to a single servlet instance (which you probably 
cannot control anyway, unless your container allows some sort of 
proprietary setting).


The way you should be thinking to solve this problem is a connection pool.

Your servlet needs to be written in a thread-safe manner anyway, and 
that allows the same servlet instance to handle multiple requests at the 
same time.  Having a connection pool underneath that will allow you to 
share your database connections efficiently.


There are numerous options for connection pooling... the first thing 
you'll probably want to look into is what your container itself offers 
in this area.  Most containers have some sort of pooling facility 
available.  Another option is to build on top of a persistance framework 
like Hibernate or iBATIS, both of which offer some degree of pooling 
support.  There are libraries for doing it as well, DBCP (a Jakarta 
Commons package) for instance.  You could always write your own, it 
isn't too tough, but for something that has been done to death you are 
definitely better off not bothering.


Of course, since your posting to the Tomcat list, I can tell you that 
Tomcat offers such support:

I am going to make my servlet be static, with the hope that

What do you mean by "servlet be static"?  What syntactical construct are
you employing?

If you mean using static fields in your servlet class, then you will
have to make use of synchronization clauses to insure concurrent
requests are serialized.  It's my understanding that the container
(Tomcat or whatever) is free to process as many requests in parallel as
needed, as well as create multiple servlet instances - see the servlet
spec.

What problem are you trying to solve?



  My plan is to try:
public static class SomeServlet extends HttpServlet {  ... }

  That way there should only be one servlet.

  I am writing a servlet to save grades to a database, but,
unfortunately, instructors will procrastinate like students do. So, I
expect that 2000+ instructors will submit their grades in the last hour
or so, before the deadline.  If each instructor had their own db
connection then the system will be useless, as students won't be able to
get connections, since all the connections will be used up.

  For the first test I want to limit them to only one connection that
will read from an input queue, and just process all the grades. Later it
may be bumped up to 20-50 connections, to speed it up.

  That is the basic problem I am trying to solve.

  I am actually using XmlHttpRequest to connect to the servlet so it
doesn't lock up the browser.

Re: ServletContextListener - how to detect http path of web application?

[Frank W. Zammetti]

Tim is right, you can't do it directly.  You *might* be able to construct
it in a roundabout way though...

Let's assumg you know the method, http vs. https, and its always one or
the other.  Let's also assume that the  element in web.xml
names the application context (i.e., if the URL is http://myserver/myapp,
then myapp.  I believe the following (without
actually trying it) would work...

String s = "http://";;
s += new InetAddress.getHostName();
s += "/" + servletContext.getServletContextName();

Kind of hack solution, but it might be OK for your application (assuming
it actually works!)

One reason a filter would be better is you can fully construct the URL
dynamically, including the method and all that.  Could you possibly map it
to just the initial entry point of your app so that it doesn't fire with
each request?

Another even more hack-ey solution might be to have a servlet that runs on
startup, and from it fire off a request to a specific URL that goes
through your filter.  Your filter then calculates the app's URL and sticks
it in application scope.  The servlet is no longer needed, nor is the
filter, and shouldn't affect anything after that.

Seems like a lot of trouble for what your after though :)

Although, how would the startup servlet know what the magic URL is? I
guess it would have to start with the full URL of the app. Which is
where we came in :)


The startup servlet wouldn't, the filter would.  The servlet just
requests a resource in your webapp, and the filter calculates the URL
and sticks it in application scope.


Doesn't matter anyhow, it's working ok... Thanks a lot for your help.

Re: login

[Frank W. Zammetti]

What you describe is referred to as container-managed security, or J2EE 
Security.  Here is a link I think may help you:


http://www.onjava.com/pub/a/onjava/2002/06/12/form.html

The actual configuration of the security constraints is J2EE-standard 
and pretty easy.  The configuration of roles and groups and such is 
container-specific and while not usually difficult in any way, will vary 
from container to container.  That link discusses Tomcat specifically 
though, so it should get you heading in the right direction.

How are you trying to access the elements and from where?  You will need
to properly traverse the DOM to get at the elements you want (I usually
use window.top. where  is the name assigned to the frame, which I
notice you don't have).

Remember that frames are separate documents entirely, it is not like doing
an include.  Based on the structure you show here, which is somewhat
atypical, I suspect your thinking of it as an include, and hence the
problem your seeing.

Re: Accessing Files outside of WebApp

You may want to have a look at the ResourceServerServlet in Java Web Parts:

http://javawebparts.sourceforge.net/javadocs/javawebparts/servlet/ResourceServerServlet.html

That may give you what you want.  It allows you to serve any resource from
a variety of sources (currently file system from any location, a URL or a
JAR file).  It is also extensible if you would like to serve from another
location.

Re: Image Scaling Code

[Frank W. Zammetti]

I don't quite see how this is Tomcat-related, but...

Your code can't connect to your X server, which is necessary for many 
Java graphics-related functions to work on a *nix system.  I dealt with 
this at one point when getting DataVision working on Linux, and I recall 
the solution being something to do with an environment variable, but the 
exact answer eludes me.


Actually, it looks like you *have* defined the environment variable 
(DISPLAY in the stack trace rings a bell).  Is X running?  I believe it 
has to be for this to work.

Re: Size of session bean

[Frank W. Zammetti]

That's an interesting question... looking at the code I wrote in Java 
Web Parts for the getSessionSize() method, I'm only taking into 
consideration the fields of the objects in session.  I think this is OK 
because IIRC, when an object is serialized, only the non-transient 
values are considered.  The methods don't factor into it because you 
aren't serializing the class definition, just the state of the object. 
If anyone knows differently I'd like to hear about it, but I believe how 
that method works yields an accurate result.


If you want to see how I've done it, check out:

http://javawebparts.sourceforge.net

If you look at the javadocs, in the session package, there is a class 
called SessionSize that is used to get the size of a session object. 
You can grab the code and see how it's done, or just use it if that's 
your ultimate goal :)


Frank

Robert Palmer wrote:
When calculating the size of a session bean to determine memory usage, 
what should be included and how is this done? Do the number of methods 
matter? The size of the code? Just the variables? I've read much about 
limiting the size of the session information but not how to do it. I 
have some fairly large classes in session context but they don't store 
very much.

Re: Spawning a thread

[Frank W. Zammetti]

Most of the time people will tell you "don't do it", but don't get any 
more specific than that.  Generally-speaking, spawning a thread to 
process a request is somewhat of a bad idea because the container is not 
responsible for managing the thread and therefore you run some extra 
risks.  But, if you have something like a background process that isn't 
tied to a request, with the caveat the other poster made about daemon 
status in mind, I've never had a problem, and I've done it quite a bit.


I think the prudent advice is "be careful".  And, if you can do what you 
need to without spawning a thread, you might be saving yourself some 
trouble down the road.  But, if you are careful and do it smartly, there 
isn't any definitive rule (that I am aware of) that says you can't do it.

Just to clarify, George wasn't talking about a "context listener

referring to is spawning a thread *from* a context listener.  Subtle 
semantic difference, but it completely changes the meaning :)

A good way of starting threads not tied to a request is to have a context

Re: data file access for servlet

[Frank W. Zammetti]

Hi Neha,

You can basically put it wherever you want because your servlet can get
direct file system access (I'm not sure this is true if deployed in an
EAR, but I guess that's not an option here anyway).

Where it *makes sense* to put it is up to you... if it's something
specific to the webapp then it probably makes sense to put it somewhere in
the webapp's directory structure, but if it's more a shared data type
thing, it might make sense outside the webapp.

Take a look here:

http://cvs.sourceforge.net/viewcvs.py/javawebparts/javawebparts/WEB-INF/src/javawebparts/servlet/TextReturnerServlet.java?view=markup

Scroll down to the init() method and see how it gets an InputStream to the
itemsFile.  This is how you can do it context-relative.  If you want to go
to something outside the webapp, take a look at
ServletContest.getRealPath().

Re: data file access for servlet

[Frank W. Zammetti]

Take a look at getRealPath() as I suggested earlier... you should be able
to get at the home directory of that other software using it (assuming all
the security that might be in place doesn't get in the way).  You will
probably want to make the path a config parameter so you don't have to go
changing code when that home directory inevitably moves later on :)

Re: How can I take a webapp "temporarily out of service" using mod_jk?

[Frank W. Zammetti]

Hi John,

A filter should do the trick for you.  Have it interrogate some value
somewhere (context value? static class? database?) and when it sees a
particular value, redirect to your out of service page.

Since your in a cluster, you have the problem of replicating this "out of
service" flag to all the nodes... a database would be the obvious answer,
but clearly that has performance implications.  You may need some special
URL in your app that sets the flag, properly secured of course, and make
yourself a quick little page that fires it to all nodes.

RE: How can I take a webapp "temporarily out of service" using mod_jk?

[Frank W. Zammetti]

Ah, sorry, didn't get that.  I was suggesting servlet filters.  I don't
frankly know anything about Apache filters... if it's like a servlet
filter but before the request hits the app server, it sounds like it could
do the trick in the same basic way though.

[OT-ANN] Java Web Parts v1.0 beta3

[Frank W. Zammetti]

Hi all... I haven't been posting JWP release announcements here lately, 
and generally I will refrain from doing so, but the team just put out a 
new release last night and I think it has some features that might be of 
interest to many of you...


* AjaxTags now has some new capabilities, including the ability to have 
multiple config files, the ability to have static parameters on the 
target URLs, a built-in debugging facility and an implicit passing in of 
the ajaxRef with each request, so now you can always determine which 
element fired the event.


* The Chain implementation now supports loading config files from JAR 
files, and there is now a SimpleCommand that you can extend (instead of 
implementing Command) that has default implementations of all three 
Command methods (init(), execute() and destroy()), so you can only worry 
about the ones that interest you.


* A new popup calendar widget has been added to the UIWidgets taglib.

* JSDigester was added to the JSTags taglib.  JSDigester, as you may be 
able to guess, is a client-side implementation of our beloved Commons 
Digester.  It is not as full-featured as it's big brother, but it can 
come in *very* handy, just like the full-fledged Digester.


Take care!

As per the servlet spec, the container can unload and reload a servlet as
needed.  It is an expected *potential* behavior.  My own personal
experience would indicate it's rare, but you have to design for it.

I would expect destroy() to get called at some point before init() does a
second time, but I'm not sure if that is a guarantee of the spec.  Seems
like it probably would be though.

Implement some sort of check in init() to determine if it has fired
already or not.  A simple static boolean field on the servlet should do
the trick.  So, maybe you have:

private static boolean isInitialized;

Then in init(), you do:

synchronized (isInitialized) {
  if (!isInitialized) {
// Do initialization tasks.
isInitialized = true;
  }
}

Wow, I've had just the opposite experience with their stuff.  Especially
in terms of documentation, I've always found MSDN to be some of the best
documentation around, generally far superior to most open-source
documentation (my guess is they have some generally non-technical editors
looking it over... I can't imagine that quality of writing came from
techies!)  I will say though that they do tend to be a little short on
examples, something open-source tends to have a lot more of.

I think it's a difference in culture behind it... MS is coming from a more
"professional", business-like approach, and in that mindset writing
documentation takes on more importance.  In the open-source world, there's
much more of the "here's an example, go look at it and learn" kind of
mentality.  I'm not making a judgment on which is better, I think they
both have their pluses and minuses, just pointing out what I see as a
difference.

I'm not sure where the Access analogy comes in, but I do agree in that if
you haven't done much with the event-driven model before then it can be a
little disconcerting.  I think we're seeing the same thing in the Java
space with JSF right now... it's a basically event-driven model (they call
it component-oriented, but it's in many ways the same thing), and this is
somewhat new to many... ASP.Net is like bringing Windows programming to
the web, whereas JSF is like bringing Swing to the web... imperfect
analogies I suppose, but close enough :)

Context Path

[Antonio W. Lagnada]

Hi Everyone,

Is there an assumption or some unwritten rule on what the context path
should be when deploying a web application in Tomcat (or any other standard
J2EE Web Server)?

Should an application context like this be allowed?

   # Context 1
   context = "/myapp/app1"

   # Context 2
   context = "/myapp/app2"

I double checked the current Servlet Specification (2.4) and the document
was not very specific on what the rules are on the context path.  All it
noted was that the web application context path must be unique.

We have a lead architect that insists on deploying applications this way.
The problems where running into now is that the Tomcat deployer (/manager)
app fails to deploy the second application that has a similar appcontext
pattern (/myapp).  It's probably obvious to most of you why.

Deploy app1.war to context /myapp/app1 (using /manager)  ---> SUCCESS
Deploy app2.war to context /myapp/app2 (using /manager)  > FAILED

The only issue I see with this is that when Tomcat extracts the contents to
${catalina.home}/webapps directory it super imposes the /myapp/app1
directory when deploying /myapp/app2.

Anyways, you're worthy insights will be appreciated.

APR in Tomcat 5.5

[Antonio W. Lagnada]

Hi All,

Once I have apr installed, what is the configuration change that I need to
do to let tomcat know to use apr?

Thanks

Re: APR in Tomcat 5.5

[Antonio W. Lagnada]

Thanks.  I'm assuming I need to append it to LD_LIBRARY_PATH as such:

LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:/usr/local/apr

What about in WindowsXP? Do the dlls just need to be in C:\Windows\system32?

SSL on Virtual Hosts

[Antonio W. Lagnada]

Hi All,

As far as I know there's only one place to set the keystore in tomcat (
server.xml).



Will tomcat support https on virtual domains?

If I have placed "www.host1.com" and "www.host2.com" on my keystore, will
tomcat map the correct domain entry?  Right now I think the first entry gets
used all the time no matter what host name is being used.

https://www.host1.com  -> mapped to www.host1.com keystore entry
https://www.host2.com  -> ALSO mapped to www.host1.com keystore entry

Thanks

Re: Servlet filter on j_security_check

[Frank W. Zammetti]

Yes, it is generically possible... I have the following mapping in one of
my apps:

  
InitialLoginFilter
/j_security_check
  

This runs on Websphere though, so maybe there is some limitation with
Tomcat.  In general though, it appears it is possible.

One suggestion: change to a servlet mapping for the filter.  IIRC,
j_security_check is just a servlet that is set up by the container, so
that might work.  I kind of doubt it, but for the 30 seconds it'll take to
try, worth a shot.

If one were being sarcastic and jaded (although a bit realistic at the

select count(first_name) as c from [postings on tomcat.apache.org] where
unemployed='T' and not_married='T' and no_kids='T'

Since most of us with regular jobs don't generally have time to play with
all the things we'd like to.

(P.S., never do a count on *, it's less efficient :) )

Re: Help with detecting session timeout

[Frank W. Zammetti]

From an applet?  There probably is no easy answer... any solution would 
involve either polling the server from the servlet, or pushing the 
status out to the servlet... the later should be doable from a 
SessionListener... record the remote IP when the session is created, and 
send a ping to it when the session expires.  The problem with that 
though is when NAT and other address translation techniques get 
involved, there's a good chance it won't work.  That's why polling is 
the more usual solution in situations like this.

Re: Disappointed

[Frank W. Zammetti]

The Tomcat mailing list, like Tomcat itself, and like most open-source 
projects in general, are volunteer efforts.  People will answer what 
they feel they can, when they can.  You should start by having no 
expectation of getting an answer because you in fact may not, because no 
one knows the answer, because no one has the time to answer, or yes, 
because your question was silly (I don't know what your question was, so 
I cannot judge) or just because no one felt like answering.  If people 
deem your question to be something you should be able to answer yourself 
without much trouble, you may not get an answer (or you may get a simple 
RTFM answer).


As a volunteer endeavor, all of these are perfectly valid response, or 
non-responses, as the case may be.


One thing to keep in mind is that the open-source community is sometimes 
not the friendliest place.  Being nice is not valued as much as 
technical prowess is.  Between you and me, it personally took me a good 
deal of time to come to this understanding too.  I value people being 
cordial and helpful with each other, and I personally strive to bring 
those qualities to any post I make (sometimes I succeed and sometimes I 
don't!) but that is not a primary driver of a mailing list like this, 
technical discussion is.


I think the de facto standard to go by is codified here:

http://www.catb.org/~esr/faqs/smart-questions.html

Read this and you will understand the community-driven projects like 
Tomcat a lot better I think and be able to interact better with them 
with the proper expectations.

Somewhat OT: Multiple auth methods in one webapp?

[Frank W. Zammetti]

Hello... I marked this Somewhat OT because what I'm trying to accomplish
would ultimately be running in Websphere.  However, I would like to
develop it under Tomcat as I've always done, and it's also a general
webapp question...

I have an existing webapp that uses form-based authentication.  Now I'm
being asked to expose some Web Services from it, and I'm thinking of using
AXIS.  However, one of our requirements is that HTTP be secured with basic
auth.

Ideally I would like to add AXIS to my existing webapp, but it doesn't
seem possible to use both auth forms in a single webapp.  In a perfect
world I could continue to secure the user-accessible app with form-based
auth, but secure just the path to the AXIS-based services via basic auth. 
I'm thinking the only way is to have a second webapp, but can anyone think
of another solution?  Thanks!

Thanks Jay, I appreciate knowing at least that I'm not alone :)

Do you know, or does anyone else know, where the server looks for the
credentials when the challenge box has been submitted?  In other words,
does the entered username and password get passed as a specific header or
a request parameter?  Obviously 5 minutes of Googling would find me the
answer, but since we're already here... :)

I'm thinking that it shouldn't be at all difficult to write a
BasicAuthFilter (assuming one doesn't already exist) for doing this, which
would allow both of us to do what we want.  Should be a simple matter of
(a) sending back a 401 if no credentials are supplied, or (b) calling on
the security provider to authenticate if they are.  I would add such a
filter to Java Web Parts, and with the expanded mapping capabilities we
provide with those filters, it should do the trick nicely.

Thanks Chuck, saves me the time to find it.

But no, I'm not the guy that memorizes specs, that is very clearly Craig
McClanahan's title :)  The man's instant recall of spec is astounding!

Re: Converting characters to "ascii" value

[Frank W. Zammetti]

The first 127 characters of Unicode are in fact ASCII (might be the 
first 255, I'm not sure, but the first 127 for sure).  In other words, 
it you do:


int i = (int)'A';

will result in i=65, the ASCII value for A.  char is a numeric type 
remember, so you don't really have to cast to int, I just did it that 
way to better illustrate what was happening.


To go the other way, it's just:

int i = 65;
char c = (char)i;

That assumes i<127.

What Im trying to come up with is the simplest way of coming up with the 
numeric value associated with a given character, and to go back the 
other direction as well.  In VB, these are the ASC() and chr() 
functions.  I know how to get these values by going through a Byte type, 
but is there a quicker way to get (for example):


Starting with "B", return 66, or starting with " " (one space), return 32?
Going the other way, 66 should return "B", and 32 should return " ".

Thanks for any suggestions!
