It depends on what you call "busy". What are the busy ones doing ? and what are

We do not know your website or your application, so we cannot tell how many clients there are, what these clients are really requesting, how many requests each client is sending before going away, etc. KeepAlive means that when a client has sent its /last/ request and received the response, one thread is going to remain "not free" (but doing nothing) for the duration of the KeepAlive timeout. This thread will keep waiting, for KeepAliveTimeout seconds, just in case the client would still send another request (which it may never do, depending on the application). Imagine that your application is so that the average client - connects to your site - sends a single HTTP request, which gets processed in 0.1 s - receives the response - and then goes away and that the above sequence happens once every second, from different clients. After one second, there will be one thread waiting for another 19 seconds before becoming free (and potentially destroyed or re-used). After 2 seconds, there will be 2 such threads. After 3 seconds, 3 threads. And so on. After 20 seconds, the first thread will be freed, but there will be 19 other threads still waiting, and one new thread just created. If everything stays perfectly regular like that, your will have /permanently/ 20 threads in existence, even if the minimum is 10. If you change the above so that there is a new client every 0.5 s, you will have permanently 40 threads (of which only 2 maximum are really doing something). The point is : KeepAlive is not "bad", and in some cases having a relatively long KeepAliveTimeout is the right thing to do. Also, having a high number of threads sitting idle is not necessarily a problem. Your own scenario is probably not like the above perfectly regular and irrealistic one above. But there may be a perfectly logical reason why you have so many threads on average, and I am just trying to give you ideas for finding out the reason. > > -Original Message- > From: André Warnier (tomcat) [mailto:a...@ice-sa.com] > Sent: Monday, January 16, 2017 8:33 AM > To: users@tomcat.apache.org > Subject: Re: FW: tomcat 8080 thread not reduced > > On 16.01.2017 03:41, Smith Hua wrote: >> >> actually there is not much busy threads, less tahn 10,so i think this >> parameter may has nothing to do with this > > It depends on what you call "busy".

This is strange -Original Message- From: Philippe Busque [mailto:pbus...@mediagrif.com] Sent: Monday, January 16, 2017 8:09 PM To: users@tomcat.apache.org Subject: Re: Re: FW: tomcat 8080 thread not reduced We're having a similar issues with our numberous Tomcat instances. Our connector config look like this. Sometime, the number of active connection would jump very high (up to 190), due to some external issues (database lock, etc) and threads would accumulate. Even though a connectionTimeout is set, and therefor set keepAliveTimeout as the same value, threads are never released once the problem is resolved until Tomcat is restarted. We would end up with maybe 5-10 busy workers, but 190 idle workers/ threads I think the issue is related to how the StandardThreadExecutor is implemented. The StandardThreadExecutor is a front for the default Java ThreadPoolExecutor. If I'm not mistaken, ThreadPoolExecutor is distributing work in round robin fashion among all defined workers, rather than sticking to the core threads. As a result, should a website has any constant traffic (Apache AJP ping, load balancer monitoring, normal traffic, etc), all thread will be hit at least once within the configured keepAliveTimeout, reseting it. So unless the keepAliveTimeout is set to a very low value, which defeat the purpose, thread will never be released . This is what I've come to suspect from looking at the StandardThreadExecutor, but never really had the opportunity to do deeper test with load. But from Tomcat 6 to tomcat 8, we were never able to decrease the number of 'idle' workers back from the highest value it had reached.

I believe that what Philippe mentions below is somewhat different : in his configuration, there is apparently a front-end httpd server, which communicates with Tomcat via AJP and the tomcat AJP Connector. In such a case, the "mod_jk" or "mod_proxy_ajp" connector module inside of httpd, creates a series of connections to the back-end tomcat, and keeps these connections alive in a pool of connections, according to rules which are different, than what applies to your case (which consists of direct HTTP connections from browsers, to the tomcat HTTP connector). So Philippe's case introduces probably an additional level of complexity into the equation. semi-graphically : smith case : client <- HTTP -> tomcat HTTP connector - tomcat thread Philippe's case : client <- HTTP -> apache httpd + ajp module <- AJP -> tomcat AJP connector - tomcat thread The real question is : The tomcat 8.0 HTTP Connector documentation (http://tomcat.apache.org/tomcat-8.0-doc/config/http.html) mentions a series of attributes/parameters (maxThreads, minSpareThreads, connectionTimeout, keepAliveTimeout,..) which, together, would lead one to believe that tomcat is managing the number of threads dynamically (increasing the number of threads (up to maxThreads) when needed to process simultaneous requests, and decreasing the number of threads again (down to minSpareThreads) when less requests are being processed). According to observations however (and to Chris' comments), that does not seem to be the case : once the number of threads has grown to a certain number, it never goes down back down again. It has to be said that the above interpretation was mine, and the current documentation of the HTTP Connector never says explicitly that, on its own, it manages the number of threads dynamically. But it *does* mention a minSpareThreads parameter. On the other hand, when you use an Executor (http://tomcat.apache.org/tomcat-8.0-doc/config/executor.html), then the documentation states explicitly that the number of threads *is* dynamically managed, up and down. I found something else which seems to explain the riddle : http://tomcat.apache.org/migration-6.html#Connector_thread_pools That section explicitly says that since tomcat 6.0, for a Connector without an Executor, the number of threads always grows, and never decreases. And it also explicitly says that the Connector's "minSpareThreads" attribute will be ignored. So in fact the only thing wrong, is the online documentation for the Connectors : the minSpareThreads attribute should be removed (since it is anyway ignored). That seems to have been an oversight ever since tomcat 6.0. As far as I am concerned thus, the mystery is solved. One question which is a bit left open is : What - if any - is the real advantage/disadvantage of having perhaps maxThreads idle threads, as opposed to using an Executor to manage the number of threads dynamically ? But that is probably the kind of question to which the appropriate answer is : "it depends.."

Hi, André Thanks for the great explanation. So the current thread count will grow always until it reaches to the max configuration. I have another strange thing: We never monitored tomcat busy thread count high (we monitored one minutes interval through Nagios to get tomcat manager result, not high than 10). So if the threads grows, it should monitored the busy thread count reach that high(or some lower). So I'm still not understand when the current thread count will grow while current busy thread has not change a lot. -Original Message- From: André Warnier (tomcat) [mailto:a...@ice-sa.com] Sent: Wednesday, January 18, 2017 9:41 AM To: users@tomcat.apache.org Subject: Re: FW: tomcat 8080 thread not reduced Hi. I believe that what Philippe mentions below is somewhat different : in his configuration, there is apparently a front-end httpd server, which communicates with Tomcat via AJP and the tomcat AJP Connector. In such a case, the "mod_jk" or "mod_proxy_ajp" connector module inside of httpd, creates a series of connections to the back-end tomcat, and keeps these connections alive in a pool of connections, according to rules which are different, than what applies to your case (which consists of direct HTTP connections from browsers, to the tomcat HTTP connector). So Philippe's case introduces probably an additional level of complexity into the equation. semi-graphically : smith case : client <- HTTP -> tomcat HTTP connector - tomcat thread Philippe's case : client <- HTTP -> apache httpd + ajp module <- AJP -> tomcat AJP connector - tomcat thread The real question is : The tomcat 8.0 HTTP Connector documentation (http://tomcat.apache.org/tomcat-8.0-doc/config/http.html) mentions a series of attributes/parameters (maxThreads, minSpareThreads, connectionTimeout, keepAliveTimeout,..) which, together, would lead one to believe that tomcat is managing the number of threads dynamically (increasing the number of threads (up to maxThreads) when needed to process simultaneous requests, and decreasing the number of threads again (down to minSpareThreads) when less requests are being processed). According to observations however (and to Chris' comments), that does not seem to be the case : once the number of threads has grown to a certain number, it never goes down back down again. It has to be said that the above interpretation was mine, and the current documentation of the HTTP Connector never says explicitly that, on its own, it manages the number of threads dynamically. But it *does* mention a minSpareThreads parameter. On the other hand, when you use an Executor (http://tomcat.apache.org/tomcat-8.0-doc/config/executor.html), then the documentation states explicitly that the number of threads *is* dynamically managed, up and down. I found something else which seems to explain the riddle : http://tomcat.apache.org/migration-6.html#Connector_thread_pools That section explicitly says that since tomcat 6.0, for a Connector without an Executor, the number of threads always grows, and never decreases. And it also explicitly says that the Connector's "minSpareThreads" attribute will be ignored. So in fact the only thing wrong, is the online documentation for the Connectors : the minSpareThreads attribute should be removed (since it is anyway ignored). That seems to have been an oversight ever since tomcat 6.0. As far as I am concerned thus, the mystery is solved. One question which is a bit left open is : What - if any - is the real advantage/disadvantage of having perhaps maxThreads idle threads, as opposed to using an Executor to manage the number of threads dynamically ? But that is probably the kind of question to which the appropriate answer is : "it depends.."

Because it didn't do so in the past, before was introduced. I'm curious: if you are willing to have e.g. 200 threads available at any time during the life of the JVM, why does it matter if those threads are reduced during times of inactivity? I think of threads as a resource like memory, where if you are going to allocate X resources, you may as well allocate X resources and be done with it. Growing and shrinking pools of things just adds complexity and reduces performance. Idle threads are "free" other than using a little bit of memory.

RE: FW: tomcat 8080 thread not reduced
Hi, Chris We don't just care about free, we care about active too. We know how many free also means how many are active We are using HTTP Let's me take one example from manager status: (this is the manager output) Max threads: 200 Current thread count: 23 Current thread busy: 1 Keeped alive sockets count: 1 Current thread count: 23 I want to know if these 23 threads are free to use, or they are active, cannot accept new connection?

Why do you care how many are free? Isn't it more important to know how many are active? For example, I run my app servers with maxThreads="150" for the most part. Then, I have Nagios notify me if the "active count" goes above 135 (that's 90% of my maxThreads). Nagios, like many monitoring systems, won't scream the first time it sees something. Instead, it will check again a few times before complaining. That means that as long as I don't see any significant duration where the active thread count exceeds 135, I don't get any alarms going off. And I don't care how many "free" threads I have. I've decided that I want "150 and NO MORE". Nothing else matters except the active count. I don't happen to allow the thread pool to re-size downward (fewer threads), but if I did, I wouldn't have to change my monitoring at all. What? The active count is 10 and the total pool size is 20? I don't care. Wake me up when the active thread count stays high for a while, indicating to me that we are getting hammered. > How many are in keepAlivedStatus Use NIO and forget about it. Besides, you are using *AJP*. Every thread is *always* in a keepalive state. So keepalive == idle as far as Tomcat is concerned. If you were using HTTP, then keepalive would be an issue (and NIO would be the answer), but you aren't, so it's not. - -chris > -Original Message- From: Christopher Schultz > [mailto:ch...@christopherschultz.net] Sent: Thursday, January 19, > 2017 4:38 PM To: Tomcat Users List Subject: Re: FW: tomcat 8080 thread > not reduced > > Smith, > > On 1/18/17 8:25 PM, smith wrote: >> I don't care if the threads will be reduced, I just want to know why. > > Okay. > >> And we want to use the account to determine when the tomcat capacity >> is not enough that we need to add max configuration or add new tomcat >> servers. > > Set your initial and max threads to the same value (pool size = > constant) and then monitor the "active count" with a Nagios warning at > e.g. 80% usage. > >> Since not use the , the busy thread account also cannot >> tell us the correct active threads count. > > "busy" is the same as "active". > >> In another email thread, you said if use , it will tell us >> the right active thread count not just busy count, right? > > I would always use an for at least two different > reasons: > > 1.

Our production usage also has same phenomenon that my "currentThreadsBusy" always not high (3-5), but my "currentThreadCount" will go to 200-300 sometimes.

How to access server configuration from a servlet
I have a Tomcat 5.0 server running on a 1.4 JRE I was wondering if there was any way to access server configuration (in server.xml etc.) from a servlet? Is there a way to determine where the server is installed on the system etc.? I would like to basically determine the server's SSL keystore and password. Any help would be greatly appreciated. Thanks.
Re: How does Tomcat detect whether a browser accepts cookies
On first response, Tomcat both set's a cookie JSESSIONID and appends the same to the page links (when properly coded). If the cookie comes back on the next request, url rewriting is dropped in favor of the cookie. No magic, tomcat just covers all it's bases up front. See HttpServletResponse.encodeURL(String) in the servlet spec for more info. -- David Garey Mills wrote: David - Tomcat uses cookies to establish a session with the browser. If it can't use cookies, it uses URL rewriting. So whenever someone uses my app, Tomcat tries to set a cookie. If it was the case that Tomcat didn't know whether the browser accepted cookies until after it tried to set one at the first access, users of browsers that did not accept cookies would not have a session that recorded their first access. I don't think that would be considered acceptable, so I assume that Tomcat knows, before my app is reached, whether the browser accepts cookies. But is my assumption correct, I don't know. That is what I am asking. Garey Mills Library Systems Office UC Berkeley The brain is not where you think On Wed, 21 Jun 2006, David Kerber wrote: Why would it try until your app tells it to?

There are a number of different ways to detect it inside my application, but all of them seem to need a roundtrip to the browser. If, as I suspect, Tomcat can tell without the redirect, I would like to use Tomcat's knowledge.

RE: Out of Memory Error
I'd suggest that you try the following JVM options in your Tomcat JAVA_OPTS environment variable (before deploying these changes in production, test these options in an isolated environment with stress testing tools if at all possible): JAVA_OPTS= -Xms1024m -Xmx1024m -verbose:gc -server - By making -Xms and -Xmx the same, you will minimize CPU cycles spent on growing the block of memory allocated to the Tomcat JVM by the OS. If you have more memory available, use it for Tomcat, so long as you allow sufficient "headroom" for other services you may be running, as well as the OS itself. Test to determine how high you can safely go with these parms. - The -verbose:gc option will output statistics to the Tomcat console that will tell you the "before" and "after" memory stats behind JVM garbage collection operations. Use the "after" number to determine approximately how much RAM the Tomcat JVM is consuming at a given moment. Much of the time, the JVM does not use all the memory shown by the Windows Task Manager as being in use. - As I understand it, the -server option is generally recommended when using Tomcat in a server environment. That aside, buy enough (>=2G) RAM so that you can take advantage of a larger memory allocation. Win 2K permits a total of 4G per process; 2G of that is mapped to the OS kernel leaving 2G for your app. If you only have 1G or so installed, you're missing an opportunity for an inexpensive way to increase performance and decrease downtime and hair loss! Hope this helps.

Re: JDBC jar in WEB-INF/lib?
You can if you like. Just implement a ServletContextListener to setup a DBCP pool for your webapp and store the resulting DataSource in the ServletContext. Servlets and JSPs can pull it out of the ServletContext later for use. Then have both the DBCP jar and the MySQL jar in your WEB-INF/lib folder. The only catch is your DataSource won't be available via JNDI any more. The JNDI mechanism of tomcat requires your MySQL jar be in common/lib. --David wolverine my wrote: Hi! The Tomcat's MySQL DBCP example mentioned that we have to copy the JDBC Driver's jar $CATALINA_HOME/common/lib. Do we allowed to copy the jar to WEB-INF/lib?

RE: sort an array
Perhaps all the data items stored in the three arrays could be put into a single new class so that, by definition, all the data would be sorted together. At that point, you might not need three separate arrays. If you need to sort the data in different ways, you can avoid making copies of the List (to sort each one differently). Declare a static field in the class to indicate the sort method that you need at the moment, then read that static field in the compareTo() method. A user of that class that needs to sort a certain way would set the static field (say, through a sortMethodXXX() method you declare in the class) and call Collections.sort() as Sergio had previously suggested. If you might be calling the sort() method in a multithreaded environment, you'll have to take synchronization issues into account (to make certain that each thread uses the static field value needed to implement the sort method that thread needs). The suggestion above should work if you declare the sortMethodXXX() method as synchronized, but you'll need to test that carefully to make certain that one thread does not corrupt or delay the results expected within another thread. Hope this helps.

Yup. Gotta love Windows. You might also want to check with the domain admins to be sure some group policy hasn't been set that would interfere.

If Class.forName throws a null pointer exception, chances are it can't find the driver because you have a Tomcat configuration problem or other classpath-related problem relating to driver setup.

Re: tomcat startup problem
You may want to consider saving a copy of server.xml as server.orginal.xml (or something to that effect) and then stripping out all the comments in a production version of the server.xml. Makes reading the config s much easier. If you really need the docs, go back and take a look at the original as needed. At anyrate, I see your shutdown port in the port is the default. If you have another tomcat running (I thought I saw some reference to this in a previous post), this needs to be changed on one of them. Same for the SSL port at 8443. These errors should show in logs/catalina.out if there are real port conflicts though. --David IMRANKHAN wrote: May it be bcoz of firewall blocking this port. server.xml: factory org.apache.catalina.users.MemoryUserDatabaseFactory pathname conf/tomcat-users.xml debug="0" connectionTimeout="2" disableUploadTimeout="true" /> enableLookups="false" redirectPort="8443" debug="0" protocol="AJP/1.3" /> - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: Error while connecting to MySQL database
Ok.. 1. Don't mess with the CLASSPATH. In all modern version of tomcat, the class loading heirarchy should take care of all your needs. 2. File ownership - make sure all of tomcat's files are owned by the tomcat user. Sounds to me the db.properties file is not readable by the tomcat user account. That would account for the NullPointerException you note below if Class.forName() is receiving a null parameter as a class name. 3. This is totally unrelated to tomcat, but mysql's data files should be owned entirely by mysql. I would also recommend you take a look at the init script for mysql under /etc/init.d for details on how the path for it's datafiles are determined. I've seen distributions of mysql where /etc/my.cnf is not present and not consulted for settings. 4. I'm sure it's been noted, but org.gjt.mm.mysql.Driver is old and very out of date.

Re: Serving CSS files from a certain URL
In your Test.jsp, why don't you have something similar to:
location="${pageContext.request.contextPath}/css/Styles.css" />
I'm of course assuming tomcat 5.x.x and the web.xml file is declared for
servlet spec 2.4. This should work whether the running tomcat instance
is on your local machine or the production server.

Web designers don't run web servers or servlet containers on their machines. (I call their

different browsers. So, in my running example Test.jsp would have the following relative link
../../css/Styles.css in order for it to work in the "static" environment.
However, this relative link doesn't work when I deploy Test.jsp in Tomcat.
Suppose I deploy my web-app under /testapp context. In this case, Test.jsp
would have to link to the css file through one of the following links:
../testapp/css/Styles.css or
/css/Styles.css
Neither of which work in the "static" environment used by web designers.
I hope this elucidates the problem a little further. So, the question persists,
what is the right way to get links to CSS files to work in static as well as
deployed environment?
Thanks.

The goal of all this is to maintain only one source tree used by web designers
and Tomcat administrator and avoid changing paths in JSP files during
deployment.
I would appreciate any feedback on this.
OK, since you asked :-) -- this seems a really strange requirement;
are your "web designers" unable to run a Tomcat instance to work
in?
But in any case, using relative links to a css file works fine on a test
page I just did that mirrors your described files. So *exactly* how is
this not working for you?

Re: Tomcat intialization problem
I think you need to fix your networking issues before trying to setup tomcat. If the link you supplied is your support case, the lo network interface isn't working or properly configured. ifconfig on a console logged in as root should show the active network interfaces including at least eth0 and lo. lo should have a inet addr of 127.0.0.1. Tomcat binds it's shutdown port specifically to 127.0.0.1.

Re: Includes that Forward
Personally, I think it's bad design to have an include do a forward and then expect the forward content to replace the include. A forward, even from an include, should replace the entire content of the would be response. The behavior you are looking for could be done easily (and more cleanly) with a little jsp logic that essentially chooses to render or perform a third tier include. This is purely my opinion though. I'll take the way Tomcat handles the case over the way Resin and Jetty handle it. --David Tim Fennell wrote: Hi, I'm wondering what the expected behaviour is when a JSP that is included from another JSP then forwards to a third JSP? As an example: - start.jsp - some content on start.jsp - _include_ included.jsp - some content on included.jsp - _forward_ to forwarded.jsp - content on forwarded.jsp - some content (on included.jsp) after the forward - some content on start.jsp after the include Does the above example make sense? I was able to dig up this bug (which was closed INVALID) for Tomcat 4: http://issues.apache.org/bugzilla/show_bug.cgi?id=12578 I'm using Tomcat 5.5.17 and what happens is that *only* the content on the inner-most forwarded page is output to the response. Actually - in my case it's some code deep down in the framework causing exceptions to be thrown, but I believe it's the same problem as exhibited by the test case I've put together using three JSPs. Now, granted, the spec does say that on Forward the response buffer should be cleared, and after the forward it should be closed. So it's arguable that Tomcat is doing the right thing. However, I'll point out that Resin and Jetty 6 both do different things here - so clearly how a Forward is handled *inside* of an Include is open to a lot of interpretation. I think the problem is that the specification doesn't really address the case of a Forward happening nested inside an Include :/ Personally I feel like the only sensible option (from a user's perspective) is to treat each include in the manner of a nested transaction. So in the example above, I would expect the content from the outer (start.jsp) page to be rendered, along with the content from the inner most (forwarded.jsp), but that the content from included.jsp would be omitted in keeping with how the servlet specification defines the semantics of a Forward. Are you guys open to discussing how this is handled in Tomcat? Btw. if this is a dicussion more appropriate for the dev list, just let me know and I'll post there instead. -Tim Fennell http://stripes.mc4j.org/ Stripes: Because web development should just be easier - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Tomcat manager URL configuration for 2 tomcat instances, Apache + mod_jk

Re: Simple question, but can't figure out answer
Hi. I've been lurking on this thread for a while this morning. Here's a few things you might want to consider 1. Your perl script to serve up images is pulling from /images according to what was posted. Given that perl probably isn't chrooted to the directory your webapp is in, the image you are trying to access needs to be at /images/icc-logo.gif relative to the unix filesystem root, not tomcat's webapps/ROOT or any other webapps folder. 2. If you drop the HTML page test and just attempt to access the image directly via http://localhost/path/to/image.gif, what error do you get? 3. I take it you have the perl script for serving up images mapped to icc-logo.gif somehow in your config?

I also don't see even one reference to the admin webapp. This tells me something fishy is going on. Try this: First, I see you copied the admin webapp to server/webapps instead of moving it.

There has to be some messages about the admin webapp. The only way to not have any is if admin.xml is not stored in the correct place.

Re: Tomcat Not An App Server
Tomcat's not really an app server? Geee really, I feel so inadequate now. :-( Seriously, I think I've seen this religious war around here somewhere and it really depends on definition. No, it's not a full J2EE container, but it's definitely an app server in my opinion. Have you read the servlet spec and thought about the ServletContextListener for handling the start/shutdown of a component within your app? --David Mike Wannamaker wrote: I know that Tomcat is not really an App Server like JBoss etc... However, if I had a component that was not a web application and I wanted to start it inside tomcat how could I do that ? Is there some configuration file I would need to add something to in order to have a component started and would I need to implement some Tomcat interface to do it?

Re: JDBC Realm error
Is your Realm configured as follows:
You're orignal Realm won't work because you're mixing the Oracle schema
and the JDBC-ODBC bridge connection schema. If you use the JDBC-ODBC
bridge, you have to use a connection string for that driver. You could
(and this is MUCH better in my opinion) toss the JDBC-ODBC bridge
software and just use a true Oracle JDBC driver with a standard Oracle
connection string.

Re: Tomcat on a server
Yes, but Tomcat also pools threads and keeps them around between requests, recycling as necessary. The servlet's themselves should avoid class instance variables unless they are reset to some known state at the beggining or end of every request for this reason. --David Alan Meyer wrote: is it possible to have one tomcat running on a server and allow multiple clients to execute their programs on the tomcat running on the server without affecting other clients execution.How can we configure tomcat for this purpose? If I understand everything correctly, when Tomcat receives a request it creates a new thread and runs the servlet in that thread that matches the servlet or JSP requested. Multiple requests can be processed concurrently, whether they are requests for the same servlet or for different servlets. Each thread will normally get its own stack for automatically allocated variables and objects. Depending upon how your program is written however, it is possible for the threads to interfere with each other if they use any static variables - so you must use synchronization if it is required.

Re: [OT] Problems with file permissions
We answer all kinds of questions here. Just protocol to mark off topic posts as such. In the Unix environment, the ftp service (not to be confused with the ftp client) can depending on vendor be configured to set permissions as it receives files. I know in ProFTPd, it's set using the umask config setting. Try to find out what ftp service you have on the server and look at it's man pages for info on what config settings are available. Actually, it's not Apache that cares about file permissions, but the OS (unix in this case). Apache may start as root, but it's workers are all spawned as unprivileged users (the user 'apache' in my the case of my server) and the OS will deny access if the apache worker doesn't at minimum have read access. --David [EMAIL PROTECTED] wrote: Hi David, Thanks for that and sorry for my ignorance of Apache Tomcat but I have just moved from an old IIS server that didn't care about the file permissions.

Re: Tomcat 5.5/Axis 1.4 java.lang.reflect.InvocationTargetException
Q1) As long as I do not referece the classes, which I believe means the
classes are not loaded, then there is not problem. When they are accessed,
then it fails. The classes are in both common, shared and webapps, where
else I am supposed to place them?
First, read the classloader howto on the tomcat website
(http://tomcat.apache.org/tomcat-5.5-doc/class-loader-howto.html). Then
pick ONE and eliminate the others. If the classes are used only on one
webapp or access other classes within the webapp itself, place them in
WEB-INF/lib or WEB-INF/classes. Move up to shared or common only if the
classes are used by several webapps or the engine itself. Placing
pooled database connection drivers in common/lib is a perfect example of
classes accessed by the tomcat engine and the webapp.
Q2) How do I turn on Logging at the debug level in Tomcat, or any kind of
meaningful logging to figure out what is happening?
See the tomcat website for your version of tomcat.

and does it include setting a port for it?
I found the log that has the stdout, which was showing a couple of
exceptions, which I solved by placing the appropriate jar files in the
right
place. However, the problem didn't go away, there is something in the
Tomcat
servlet or axis (I don't know) that is handling an exception in the
server
side, because I have a try {} catch () {} where the problem ocurrs and I
don't catch anything, but the exception is returned to the client. Now
not
even an exception is thrown to the stdout or staderr files.
The problems comes when in the shared/classes files I access the
parameters
that use the classes generated by the WSDL2java tool. Those classes
are in
both
TOMCAT_HOME/shared/classes
and
TOMCAT_HOME/webapps/axis/WEB-INF/classes
I also dropped the axis jar files in
TOMCAT_HOME/shared/lib
TOMCAT_HOME/webapp/WEB-INF/lib
TOMCAT_HOME/webapp/axis/WEB-INF/lib
but I still have a problem. At this point it would be nice to at
leasts see
the DEBUG output from Tomcat, but I am not sure how to do that or if
it is
something related to axis. To make this more explicit, this example
works:
class CRLStub
...
public void getCompay(CompanyHolder company, StringHolder result)
throws java.rmi.RemoteException
{
company.value = new soap.xsd.CompanyInfo();
company.value.setCompany("Something");
result.value = "ok";
}
Now, if I try to do the following, there is no error, but obviously, the
result is not the same
class CRLStub
...
public void getCompay(CompanyInfoHolder company, StringHolder result)
throws java.rmi.RemoteException
{
jnInSharedContext.getCompany(company, result);
}
class JNIcrlInSharedContext
...
public void getCompany(CompanyInfoHolder company, StringHolder result)
{
/// No problem as long as I don't access neither company or result
}
But if I do this, then I receive the
java.lang.reflect.InvocationTargetException at the client side, even if I
try to catch the exception with a try {} catch () {} pair.
public void getCompany(CompanyInfoHolder company, StringHolder result)
{
company.value = new soap.xsd.CompanyInfo();
}
I would appreciate any kind of hint,

Re: log rotation
catalina.out is the redirected output of tomcat -- not a product of
log4j or commons-logging. As such you're best bet is to have a cron job
stop tomcat, rename the file and then restart it at say 6:00am when the
internet hits the lowest ebb of demand. That method should be safe for
all OS's.
Unix/Linux seem to handle the sudden disappearance of a file well (or at
least better than Windows) and simply create a new one. Just renaming
the file without stop/start may be an option for you on *nix systems.

Re: Tomcat fails to refresh connections when mySQL server on linux is shutdown and restarted
Best practice is to store the DataSource, not the connections in your
singelton class. Then get a connection, perform your queries, and close
the connection immediately. The pool will take care of managing the
connections including creating new ones when existing connections die
which happens when the database server is restarted.

Hi Chris, thanks for the comments. I thought since we have singleton class and creating a connection object there, we will be reusing the same connection object for all database operations.

database query/update opeartions? Yes, I will make sure I close the stmt and connection objects.

private static DataSource ds = null;
private DBManager() throws Exception

And then, for example, in a method to do query,
myCon = ds.getConnection();
stmt = myCon.createStatement();
And then close the stmt and mycon.

What would be the effect of calling 'ds.getConnection()' for every database

Subject: Re: Tomcat fails to refresh connections when mySQL server on

Seetha,
To answer Tim's question, we are not explicitly closing connection
and statement objects as the context xml has these resource parameters.
removeAbandoned="true"
removeAbandonedTimeout="60"
logAbandoned="true"
This probably means that you are leaking every single connection. :(
Shouldn't DBCP take care of creating new connection if the connection
object is stale?
You will be creating new Connection objects all the time -- basically
you'll never re-use a database connection, making the pool completely
irrelevant; you may as well call DriverManager.getConnection each time
you need to make a SQL query.
Even if DBCP /does/ clean up after you, you /really/ need to call
"close" on your statement, resultset, and connection objects in finally
blocks in your code. If you don't, your code will probably not work
if/when you switch to another connection pool, another app server,
another database, etc.
Most databases allocate lots of memory for each database connection on
the server side, which means that every useless connection you have
waiting around to be cleaned up by DBCP will be taking up memory on your
database server that could be used to serve actual requests.
Whether this solves your original problem or not, you definitely need to
modify your code to close all of those objects.

Re: Can't figure out directory structure (again:-(
According to the configurations you posted, the full path of your login servlet is /smsinfo/smsinfo/login. I doubt that was what you were really after. The URL mapping in web.xml is relative to the webapp, not the root. Also, if this is tomcat 5.x, you should put your definition in it's own xml file in conf/Catalina/localhost.

Re: Links to relative URL's from a JSP

What does the URL in your browser look like when you are access the JSP
pages? The browser constructs the full path to the image from the URL
used to request the page (JSP or HTML -- the browser doesn't know the
difference).
> My assumption is that JSP files are "rooted" in the WEB-INF directory

Nope. They are "rooted" right where they are although internal
forwarding can make the request URL different from the actual location
of the JSP. In the past, I've done stuff like src="${pageContext.request.contextPath}/WebContent/image.jpg"> to get
around these issues with an absolute path to the image. My example
assumes a servlet spec 2.4 webapp and container.

My directory structure in Tomcat goes something like this:

My assumption is that JSP files are "rooted" in the WEB-INF directory
and so must use the previous directory notation back up a directory to
access the images contained the WebContent folder where everything
else is.
Thus, I have two questions:
1) Why does this occur, and how can I modify my xml configuration
files so that JSP's reference links exactly as an html file in the
same directory would?
2) How can I change the root folder of tomcat to the
webapps/inprogress/WebContent directory, which xml files, and how
exactly should I modify them?

Ok. Confirmed. Per the servlet spec, all jars in the WEB-INF/lib folder are included in the webapp's classloader. Now, here are some questions that might help narrow down what's happening: 1. Is the jar a valid jar file? Does it's internal folder structure mirror the package structure? 2. Are there any permission problems that might prevent tomcat from reading the jar file? 3. After placing this jar file in WEB-INF/lib, did you restart the webapp from the manager or tomcat itself? 4. Is there any indication in the logs that tomcat is having an issue loading your 'foo.jar' file? 5. Is foo.jar really in WEB-INF/lib or did you do some symlink/shortcut scheme that tomcat might not follow? --David Darren Hall wrote: I wanted to confirm that jar files in the WEB-INF/lib directory were included in the classpath for my application.

There must be something very strange with your code if a css file is

I'm beginning to see my problem is a bit more complex than I had
mentioned.
Here is the situtation: I have two JSP's, login.jsp and
catalogue.jsp. Login JSP calls a servlet to do some processing. If it
is successful, the servlet forwards the request and response objects
to "/catalogue.jsp".
Whenever I access "catalogue.jsp" by entering in its absolute URL,
everything works fine. I can still have my relative img links to the
images contained in the same folder, e.g.,
However, if "catalogue.jsp" is accessed by the servlet forwarding the
request and response objects to "catalogue.jsp" then none of the usual
relative URL's work. In fact, the servlet will not even compile

This is only remedied if I use relative links to the images beginning
with ".." For example, if the image links are constructed like src="../image.jpg">. Then the forwarding, runtime compilation of the
servlet, and the image URL's in the document work fine.
To illustrate how this works, say I have 3 images, one of them with a
"correct" relative URL location, and the other two using "../" before
the image filename. If I access the JSP using an absolute URL, one of
the images will work, if I use dispatcher forwarding, 2 of them will
work.

What does the URL in your browser look like when you are access the
JSP pages? The browser constructs the full path to the image from
the URL used to request the page (JSP or HTML -- the browser doesn't
know the difference).

Nope. They are "rooted" right where they are although internal
forwarding can make the request URL different from the actual
location of the JSP. In the past, I've done stuff like src="${pageContext.request.contextPath}/WebContent/image.jpg"> to get
around these issues with an absolute path to the image. My example
assumes a servlet spec 2.4 webapp and container.

My directory structure in Tomcat goes something like this:

(Accessed through Tomcat as such:
http://127.0.0.1:8080/inprogres/WebContent

1) HTML files can use the correct local pathname, e.g., src="imagname.jpg">

My assumption is that JSP files are "rooted" in the WEB-INF

directory to access the images contained the WebContent folder where
everything else is.
Thus, I have two questions:
1) Why does this occur, and how can I modify my xml configuration
files so that JSP's reference links exactly as an html file in the
same directory would?
2) How can I change the root folder of tomcat to the

Re: ResponseWrapper and sendRedirect not working
I'm not seeing the complete sequence in your filter code, or even a
redirect. Should be something like:
doFilter(){
MyRequestWrapper reqWrapper = new MyRequestWrapper(servletRequest);
MyResponseWrapper respWrapper = new
MyResponseWrapper(servletResponse);
MyUserObj clientUser = MyUserObj.getValidUser( servletRequest ) ;
if ( ( clientUser == null ) || ( clientUser.invalid() ) )
servletResponse.sendRedirect( "myLoginPage.jsp" ) ;
else {
chain.doFilter(reqWrapper, respWrapper);
respWrapper.addCookie(NAME, encrypt(myobj));
}
}
Obviously I'm not familiar with the exact API of your code, but you get
the idea. If the cookie isn't present or invalid, send a redirect to
the login page. Otherwise chain on to the next step in the request process.

Chris,
This is the complete sequence
1)User goes to a URL (say www.some-partner-site.com)
2)He selects our app link from there which redirects him to our site
(www.paybytouch.com)
3)Filter is applied on all url's
4)The filter has a wrapper class for both request and response.
5)The doFilter calls a servlet which checks if the user is authenticated
6)If the user is not authenticated, he is redirected to a login page
(say www.paybytouch.com/login)
7)Once the user is authenticated, the servlet returns to the filter
which then creates a cookie and the reponse is sent back to the users's
browser.
What happens is that the login page is never displayed. I have validated
the flow (using debugger) and it seems to be correct.
So I was wondering if a response wrapper needs to do anything special in
order to do a redirect.
My filter code does the following...
doFilter(){
MyRequestWrapper reqWrapper = new MyRequestWrapper(servletRequest);
MyResponseWrapper respWrapper = new
MyResponseWrapper(servletResponse);
//get cookie from request and decrypt it.
chain.doFilter(reqWrapper, respWrapper);
//create a cookie and encrypt it
respWrapper.addCookie(NAME, encrypt(myobj));
}
Any suggestions ?

RE: Response time banding
Depending on your application server topology, you might see the larger response times as a result of bandwidth limiting or network configuration. The issue could also be due to database access (e.g. table locking issues that are shown during the longer response times).

But while the bulk of response times are below about 0.25 seconds (in most cases considerably below), there is a banding effect where we get a cluster of response times around 2 seconds, and another cluster around 5 seconds, with little or no values in between.

Re: Back to 404 problem: The requested resource (/Sisc/servlet/servle ts/PesquisaTabPeriferica) is not available

Dear All,
I implemented the suggestions from the list but the 404 problem still
persists.
I have an application called Sisc
Under Sisc there are package1 package2 package3... and a new package called
servlets with all my servlets (note that the name has a S at the end).
I included 'package servlets;' as first line of all servlets

Am I missing something
The weird thing I noticed is that sometimes the servlet
'PesquisaTabPeriferica' works fine, sometimes it does not and I get 404
message (specially when I clean browser history, delete files and off line
files). When the servlet 'PesquisaTabPeriferica' works the other one
'RegistraMarcaPropriedade' does not.
I have no clue of what is going on. This never happened to me before. I am
losing confidence regarding TOMCAT and don't know what to do.
Can someone help me please. I do appreciate your feed back.
These are my calls from the application:

Re: Tomcat 5.5.17 can connect to any webserver without mod_jk ?is this true?
In that context, yes. Basically you are setting up a reverse proxy from your Apache/IIS front-end to tomcat. In that event, each connector in tomcat dedicated to a specific Apache/IIS front-end will need the proxyName and proxyPort attributes so it can correctly generate URL links. As for the howto, it looks like you already found one. There are other docs on the web. Word of Warning: Be careful with the proxy setup in your Apache or IIS service that it doesn't become an open proxy. --David Raju Balugu wrote: Hi Mark ,I have a doubt on this again ,I got one more link stataing we can use this feature by acting as the proxy.. http://tomcat.apache.org/tomcat-5.5-doc/proxy-howto.html just have a look and let me know ur idea.

Re: Tomcat Upgrade
For what it's worth, I don't think the changes between 4.0.x and 4.1.x are all that significant -- same servlet spec, same deployment as I remember.

Re: Initializing Parameter
ServletContextListener is a new feature of servlet spec 2.4 (tomcat
5.0.x, 5.5.x). The essential parts are:
1. write a class implementing the javax.servlet.ServletContextListener
interface. The interface itself requires two methods --
contextInitialized() [see below] and contextDestroyed().
2. Add the listener to your web.xml in a attribute.
3. Deploy your app and the contextInitialized() method below will be
executed once each time the webapp is started.
The servlet spec itself and the servlet api javadocs have complete
information on implementing this.
--David
Ryan O'Hara wrote:
You're looking for . You can add these parameters to any
filter or servlet, or at the top-level for the entire webapp, and get
them when the filter or servlet runs (or any time you can get an
instance of the ServletContext which represents the webapp).
The usual way of doing this is to create a ServletContextListener which
implements the init() method, grabs the values from the
parameters, and stuffs them into the "application" scope. Although this
is typically called the "application", you get it like this:
public void contextInitialized(ServletContextEvent sce)
{
ServletContext application = sce.getServletContext();
String myParam = application.getInitParameter("my-param");
application.setAttribute("myParam", new Integer(myParam));
}
You can pretty much do anything you'd like at this point.
Hope that helps,

Hey Chris,
Awesome, I do in fact use param-name and param-value (init-param).
So, I understand I have to make an addition to web.xml like:
variableName
variableValue
However, I'm not exactly sure what I'm supposed to do after this. I
see that your code accounts for non-String variables by binding an
object to the param-name (via setсttribute()), but I'm not sure of a
couple of things. Where would this code go that gets and sets the
value, so that it would only run once collectively for all users (not
once per user)? More specifically, would this be executed during a
restart of Tomcat? If so, how (by what class/method)?
Thanks for your quick response. Your help is greatly appreciated.

Well this is supposed to be an "SQL Server 2000" database server.
Use it's client tool to connect to the database. If successful, your
server is running. I'm not familiar with the product, but if you can
find it in the preferences, make sure you connect via TCP just like
tomcat would.

Re: Tomcat 5.5.17 can connect to any webserver without mod_jk ?is this true?
mod_proxy is the old proxy that Apache has had since 1.3 or earlier. Basic idea is to pass on the incoming request to another server. mod_proxy_ajp was introduced in Apache 2.2 to extend the mod_proxy module with the ability to pass client HTTP requests back to a tomcat instance via the AJP/1.3 protocol. Think if it as incorporating the functions of mod_jk into mod_proxy. --David Raju Balugu wrote: Thanks to David Smith and Mark Thomas .

Re: org.apache.tomcat.dbcp.dbcp.SQLNestedException: Cannot create JDBC driver of class '' for connect URL 'null'
And you are sure your test with the client software was via TCP, not
some other piped/ODBC connection scheme? I'm guessing this is a Windows
system. Have you checked your firewall for allowing the connections?
Also try using TCPMon from sysinternals.org to see what's happening with
connections to the database. It's good at showing net connection on a
Windows box in real time.

Well this is supposed to be an "SQL Server 2000" database server.
Use it's client tool to connect to the database. If successful, your
server is running. I'm not familiar with the product, but if you can
find it in the preferences, make sure you connect via TCP just like
tomcat would.

Hmmm connection refused. Is your server listening for connections
at jdbc:sqlserver://localhost:1433 ? Can you verify it independently?

Re: org.apache.tomcat.dbcp.dbcp.SQLNestedException: Cannot create JDBC driver of class '' for connect URL 'null'
I think you have your answer. The SQL Server is not setup to listen on
1433 or not running. Address this and things should start working.

Thanks David, Raju and Johnny for your time and valuable suggestions.
To David's question: I checked Client Network Utility service for SQL server
2000 and saw that TCP/IP is enabled on port 1433. I do check the firewall, yes
it was on. It has the option of adding exceptions to allow programs/service to
connect to the machine. So I added SQL server 2000 on port 1433. I did netstat
-an on command prompt to see active connection... but port 1433 is not listed.
I also used sysinternals.org as suggested and SQL Server is not listed. This
might mean SQL Server is not using TCP/IP on port 1433???
To Raju's question... I have tried to read and re-read tomcat manual... I will check if there is anything I missed. I am also trying to see how I can apply the solution suggested on the link provided.
Jonny - SQL Server is installed as default instance... TCP/IP was enabled on
port 1433.
Any further help is higly appreciated.
Thanks a lot.

David,
I do not know if the 3rd party app has hard-coded paths. I grepped for
tomcat in the app directory and below and I see a couple of places where
it is doing a System.GetProperty("tomcat.home"), but that's about it.
