Tomcat 9 returning 404 for audio files
I just upgraded a legacy application from Tomcat 7 to Tomcat 9. It's deployed as a war file. I'm facing a weird issue with audio files playback. When loading a page that contains an audio file. First time Tomcat returns 404 error but if reloading the page, audio file is loaded properly and no error from Tomcat. I'm using html 5 audio control to display the file. All other static resources(images, css and js files) are working without any issues. Only audio files are having this issue. I enabled the logs for DefaultServlet in Tomcat. Follwong is the log entry when I try to open the audio file first time. I can see 404 being returned from server in Chrome dev tools. *09-Mar-2024 20:12:50.747 INFO DefaultServlet.serveResource: Serving resource '/wav/2B916004DFE94FA40446429E1671C893_0001053.mp3' headers and data* Following is the log for 2nd attempt. This time audio is available and playable in browser. *09-Mar-2024 20:13:00.371 INFO DefaultServlet.serveResource: Serving resource '/wav/2B916004DFE94FA40446429E1671C893_0001053.mp3' headers and data * *09-Mar-2024 20:13:01.372 INFO DefaultServlet.serveFile: contentType='audio/mpeg'* Here is the audio control code: I've tried relative path and full path but result is the same in both cases. I've spent days trying to solve this but no luck :( I would really appreciate any guidance to solve this issue. Thanks!
Re: Tomcat 9 returning 404 for audio files
Thanks for replying!! Yes audio files are generated dynamically from DB.in a Servlet. I've verified that audio file exists on file system before returning the html code that contains audo control.

Re: Tomcat 9 returning 404 for audio files
On the server side, I'm checking that file exists before returning the file path to the browser. We are also dynamically creating pdf files this way and no issues with accessing them. I found something interesting: https://tomcat.apache.org/tomcat-9.0-doc/config/resources.html From this link: *Resources are cached by default.* I'll try with *Cache-Control* request header and see if it helps! Thank you!

Service is running on Windows, I've verified no access issues! Issue occurs only the first time, Subsequently audio loads properly. Thank you!

Re: Tomcat 9 returning 404 for audio files
Hi Chris, I'm creating the audio file dynamically from DB and I check if the file exists using File.exists() method. Before returning the html code with audio tag, I'm verifying that file exists on File System. Thanks!

Putting it under WEB-INF/lib isn't doing anything for you (if using loadLibrary). You could use System.load and get the exact loacation of the file using the servlet methods to get the full path and then call that to load the file directly without leaving it up to path loading and name matching. I do this when I want definite version control over the version of a library I'm using. Now, for the UnsatisfiedLinkError, have you debugged this? One, debug the java code (you can run the debugger in tomcat just like other java applications). Step to the line or set a break point and see what other setup maybe isn't getting initialized when this happens. Next, but probably what I would actually do first, debug your C library. Setup a breakpoint in the entry point (DllMain) and see if it is loading or starting to load and maybe bombing out there..it may be bombing out in some static section of your DLL before you even get to your entry point.

Configuring Tomcat Service Wrapper for remote debugging.
I am having trouble finding info on how to configure the Tomcat Wrapper Service (Tomcat 5.0.x) for remote debugging. The Tomcat "How TO" page lists the following: "If you run Tomcat using service wrapper, check the documentation for the service to determine how to set the required JVM options." I cannot find this documentation. Sam Ganzman Channel Logistics LLC (856) 428 9201 X 111

Re: Tomcat JConsole
Hi, I m using Eclipse 3.4 (in Vista) and Tomcat 5.5 (in linux) as J2EE development environment. I want to build a online order form to interact with backend database in linux. I know I can use dreamweaver to create web page (html template), but I don't know how to use it and dont' have the time to learn it. Is there any standard jsp package or library I can use from Eclipse or Tomcat to build an online order form? How about Struts or Springs library? Your suggestion is highly appreciated.

establsh remote db connection
Hi, I triedto follow the tutorial shown in the link below http://java.sys-con.com/node/152270 but I amstuck with the mysql location. I haveinstalled mysql database engine in a linux server. Thetutorial I am following on is started in windows Vista with Eclipse 3.4, it assumed we installed mysql in the local system (windows ). I havedownloaded its tutorial files in a zip file and saved them in windows vista. The list1 file is also shown below: xml version='1.0' encoding='utf-8'?> factory org.apache.commons.dbcp.BasicDataSourceFactory url jdbc:mysql://localhost/test?autoReconnect=true password maxActive 100 maxWait 5000 driverClassName com.mysql.jdbc.Driver username ODBC maxIdle 2 where should I make change in this file in order to make this project look for db connection in my linux box?

java version in windows and tomcat server
Hi, when I create a web project in windows Eclipse (3.4), I use jre6. But in my tomcat server (linux), it s using jre5. Do I have to make the jre version to be the same for both platforms? Because if I package it in a war file in windows, the lib jar files are all in jre6 version. Then when I deploy this war file to the tomcat server, will it still work? Thanks >

how to reference a class to the current src directory.
Hi there,
I have created a Web project using Eclipse 3.4. However, it can't resolve
the class reference to the current directory.
Here is the project layout and description of the problem:
>DBTest
>src
> command
CommandExecutor.java
...
...
DatabaseCommand.java
...
Double-clicks on the file CommandExecutor.java, it display the following
content:
package command;
import java.sql.Connection;
import java.sql.SQLException;
import javax.sql.DataSource;
import javax.naming.InitialContext;
import javax.naming.Context;
import javax.naming.NamingException;
/**
* Gets and caches data sources, gets connections
* Implements Singleton pattern
*/
public class CommandExecutor {
private static CommandExecutor myOnlyInstance = null;
private DataSource ds = null;
// accessor method for the singleton
public static CommandExecutor getInstance() throws NamingException {
if (myOnlyInstance == null) {
myOnlyInstance = new CommandExecutor();
}
return myOnlyInstance;
}
// Constructor for the singleton
private CommandExecutor() throws NamingException {
getDataSource();
}
// get the data source from initial context
public DataSource getDataSource() throws NamingException {
if (ds == null) {
InitialContext ctx = new InitialContext();
Context envCtx = (Context)
ctx.lookup("java:comp/env");
ds = (DataSource) envCtx.lookup("jdbc/TestDB");
}
return ds;
}
// get the SQL connection from the database
public Connection getConnection() throws NamingException,
SQLException {
return getDataSource().getConnection();
}
// execute particular database command
public Object executeDatabaseCommand(DatabaseCommand c) throws
Exception {
Connection conn = null;
try {
conn = getConnection();
Object o = c.executeDatabaseOperation(conn);
return o;
} catch (SQLException e) {
throw e;
} catch (NamingException ne) {
throw ne;
} finally {
if (conn != null) conn.close();
}
}
}
The DatabaseCommand has error. Move the cursor onto the name of
DatabaseCommand, an error message popup:
DatabaseCommand cannot be resolved as a type
3 quick fixes available:
. Add type parameter "DatabaseCommand" to "CommandExecutor"
. Add type parameter "DatabaseCommand" to
"executeDatabaseCommand(DatabaseCommand)"
. Fix Project Setup...
I think I need to choose the third option "Fix Project Setup".
Now, from Java Build Path, under the Source menu tab, it has the the
following layout:
DBTest/src
Included: (All)
Excluded: (None)
Native librarylocation (None)
Look back the very beginning of this post, you can see the class file
DatabaseCommand.java file is already defined in the same directory as as
CommandExecutor.java defined.
How to tell Eclipse compiler that the DatabaseCommand class is in the same
directory as the CommandExecutor.java?
Thanks
Sam
Re: RE: how to reference a class to the current src directory.
Hi,
Thanks for the help.
Can you tell me how to compile these .java files into classes in
Eclipse(3.4)?
All these java files are under "command" package.
Thanks

Re: RE: how to reference a class to the current src directory.
I just found out I have a class missing in the src (command) directory.
I need to create a Customer and Order class and .java file.
The Cusotmer and Order class is related to the database tables Customer and
Order.
I am wondering how to create a getters and setters of Customer and Order
class in Eclipse?
thanks

how to create domain.Order class
Hi,
I have a java class file CreateOrder.java with the following coding:
package command;
import java.sql.Connection;
import java.sql.SQLException;
import java.sql.PreparedStatement;
import domain.Order;
/**
* Create Order in the database
*/
public class CreateOrder implements DatabaseCommand {
private Order order;
public CreateOrder(Order o) {
this.order = o;
}
public Object executeDatabaseOperation(Connection conn) throws
SQLException {
// Create order
PreparedStatement sta = conn.prepareStatement("INSERT INTO
ORDERS (ID, CUST_ID, DATE_PLACED, AMOUNT) VALUES (?, ?, ?, ?)");
sta.setInt(1, order.getId());
sta.setInt(2, order.getCustId());
sta.setDate(3, order.getDatePlaced());
sta.setInt(4, order.getOrderAmount());
int rows_inserted = sta.executeUpdate();
sta.close();
return rows_inserted;
}
}
Can anyone tell me how to create domain.Order class?
I am using Eclipse 3.4, the project name is DBTest with the following
structure:
> DBTest
Deployment Descriptor: DBTest
Java Resourse: src
+command
...
CreateOrder.java
...
Libraries
Build
WebContent
JavaScript Support
I am wondering where to create a domain.Order class/java file. Do I have
to create a directory domain under src/ directory and then create
Order.java file inside theh domain folder?
Thanks
Sam
Can't generate class file from Interface
Hi,
In Eclipse 3.4 (not sure about the previous version), I have a project, in
the src, there is a interface file called "DatabaseCommand.java". This file
is an interface file.
It s content is shown below:
package command;
import java.sql.Connection;
import java.sql.SQLException;
public interface DatabaseCommand {
public Object executeDatabaseOperation(Connection conn) throws
SQLException ;
}
Another file CreateOrder.java *implements* this interface.
Its content shown as below:
Package command;
import java.sql.Connection;
import java.sql.SQLException;
import java.sql.Statement;
import java.sql.ResultSet;
import java.util.ArrayList;
import domain.Customer;
/**
* List existing customers in the database
*/
public class ListCustomers implements DatabaseCommand {
public Object executeDatabaseOperation(Connection conn) throws
SQLException {
// List customers in the database
ArrayList list = new ArrayList();
Statement sta = conn.createStatement();
ResultSet rs = sta.executeQuery("SELECT ID, FIRST_NAME,
LAST_NAME, ADDRESS FROM CUSTOMER");
while(rs.next()) {
Customer cust = new Customer();
cust.setId(rs.getInt(1));
cust.setFirstName(rs.getString(2));
cust.setLastName(rs.getString(3));
cust.setAddress(rs.getString(4));
list.add(cust);
}
rs.close();
sta.close();
return list;
}
}
When I press Clt-B to build the project(All), DatabaseCommand.java does not
get compiled, no DatabaseCommand.class generated in the
build\classes\command\ directory. The syntax highlithed in the
CreateOrder.java file indicated that DatabaseCommand is an unknown type,
that meant no class found.
How can I get around this issue? may be I should ask how to generate an
interface dot class file (eg. DatabaseCommand.class in this instance)?
Thanks
Sam
Can't execute servlet project
HI tere,
I have completed a servlet project in Eclipse (3.4).
I also made a war.file by seleting the project name (DBTest in this case)
and the export command from the Eclipse menu, and export it to the Tomcat
5.5.26 server in linux using manager.
However when I click on the project name (/DBTest) in the manager webpage,
it shown the following error:
=
HTTP Status 404 - /DBTest/
type Status report
message /DBTest/
description The requested resource (/DBTest/) is not available.

Here is the jsp file in the tomcat server:
linux:~/tomcat/apache-tomcat-5.5.26/webapps/DBTest # ls
. .. META-INF WEB-INF customers.jsp
its content is shown as below:

it shows different errors:

I haven't create any *bean*, but servlet only.
How to get fix problem?
Your help is much appreciated.
Thanks
Sam
Re: Re: Can't execute servlet project
Hi, thanks for trying to help.
I dont' have a clue on this *bean*.
The entire tutorial doesn't mention about how to setup a bean...
The tutorial I;ve followed is shown as below:

HI there,
It sounds logical, but there is no LIstCustomers in the DBTest folder.

I found there are some xml file in the conf/ directory:
linux:~/tomcat/apache-tomcat-5.5.26/conf # ls
. Catalina catalina.policy logging.properties
server.xml web.xml
.. DBTest.xml catalina.properties server-minimal.xml
tomcat-users.xml

do I need to remove DBTest.xml and web.xml here?

Re: Re: Can't execute servlet project - it works now
After this final changed (renamed the context.xml file to DBTest.xml), it
works fine now.
Thank you very much for the help along the way.
Without your patient and effort, I wouldn't be able to get this going.
Thanks

Good JSP editor
Hi there, I know it is better for me to ask this quetion in a jsp forum, but I couldn't find one for mailing list . And you guys are very helpful too in terms of this experience. If you are using a good jsp editor, can you tell me where its download link? My current development enviornment is Eclipse 3.4 and Tomcat 5.5.26 Thanks

Exception Thrown in a JSP
I am trying to figure out how to debug the following exception that's thrown in
one of my jsps. The line number from the exception trace is 259. If this is a
line number from the underlying jsp then the line is: <%@ include
file="inc/footer.jsp" %> this is also the last line in the jsp. If, on the,
other hand the line is from the resulting servlet code the line is:
out.write("channel =\"460022903\";\n"); This also makes no sense. Here's the
complete stack trace:

APR Library with JBoss/Tomcat
I notice my new version of JBoss (4.2.1GA) gives the following message in the server logs: 2007-08-05 15:41:32,650 INFO [org.apache.catalina.core.AprLifecycleListener] The Apache Tomcat Native library which allows optimal performance in production environments was not found on the java.library.path: ../lib I wen't to the Apche APR site (a more cryptic site is hard to imagine. :):)) And downloaded the source code for Windows. I build the apr library using Visual C++ now my question is where does the static library go? Does Tomcat have to be built using this library or can it be dropped in the Java library path has the message above says. The APR site is silent about how to actually deploy this library.

I saw all that but again it doesn't say where those dlls get deployed...?

grant codeBase not working for my jar
Hello all,
I have a Servlet running on tomcat-5.5.20, Ubuntu Feisty Fawn, which
is accessing some hardware through a shell script. The following
provides adequate permissions for everything to work
grant {
permission java.io.FilePermission "/bin/sh", "execute";
permission java.io.FilePermission "/tmp/thinktank-scanner.bmp",
"read,delete";
};
However, you may notice that the "grant" provides this level of
access to *all* Servlets and JSPs. I'd like to restrict the
permissions to just my Servlet.
My application is mounted on /scanner and the servlet is mounted on /
scanner/scanner, the only jar file in the application is located at
/var/lib/tomcat5.5/webapps/scanner/WEB-INF/lib/scanner.jar
As far as I understand it, if I change my permissions to
grant codeBase "jar:file:${catalina.home}/webapps/scanner/WEB-INF/lib/
scanner.jar!/-" {
permission java.io.FilePermission "/bin/sh", "execute";
permission java.io.FilePermission "/tmp/thinktank-scanner.bmp",
"read,delete";
};
then everything should work... but it doesn't. Instead I don't get
any permissions in my Servlet to do what I need to do.
Does anyone have any ideas?

Hmm, where should I expect to see the extra debugging output. It isn't in any of the log files. The permissions are perfectly fine... it is in the assignation of the permissions to the correct jar file/servlet that things are getting messed up. Will the debugging output really point to that?

Aah! That's why I wasn't seeing it. There is a pretty bad bug in
Ubuntu which puts the output into a pipe which is never read. The
standard workaround to allow tomcat to start up is to pipe it into /
dev/null (unbelievable! and it's been like this since the year
began)... report is here https://bugs.launchpad.net/ubuntu/+source/
tomcat5.5/+bug/97096
Anyway that's not all that important. I was able to redirect it to a
file and have obtained the output. Again, it's quite clear that the
permissions are not being set for my jar file
access: domain that failed ProtectionDomain (file:/var/lib/tomcat5.5/
webapps/scanner/WEB-INF/lib/scanner.jar )
despite the fact that the security policy is
grant codeBase "jar:file:${catalina.home}/webapps/scanner/WEB-INF/lib/
scanner.jar!/-" {
permission java.io.FilePermission "/bin/sh", "execute";
permission java.io.FilePermission "/tmp/thinktank-scanner.bmp",
"read,delete";
};
I've even tried it with "file:${catalina.home}/webapps/scanner/WEB-
INF/lib/scanner.jar" and with the explicit path "file:/var/lib/
tomcat5.5/webapps/scanner/WEB-INF/lib/scanner.jar", but no success..
(remember, these permissions are correct... it works when I remove
the explicit codeBase piece). I'd be greatly obliged if somebody
could please see if my syntax for specifying a jar file is correct.
log output follows:

Tomcat upgrade and JSTL XML library
Hello,
I have a web application that uses JSP 2.0 tag files and the Jakarta
standard implementation of the JSTL. Essentially, I have JSP files that use
custom tag files, both of which use the JSTL XML tag libraries for XML
manipulation. Under Tomcat 5.5.17 and earlier, in my tag file, I was able to
do something like:
<%@ taglib prefix="x" uri="http://java.sun.com/jsp/jstl/xml"; %>
This is some content
''
And this would correctly display "'This is some content'" in the generated
HTML. Once I tried to deploy the above in any Tomcat version 5.5.20 or
above, this failed to work, and would only display the single brackets, not
the content ("''"). What does work is changing the line above to:
''
Basically removing the foo part of the xpath. I am using the same version of
the jstl jars in both cases, the only difference is Tomcat. Obviously, I
could go through and change every place where the is used, but would
rather not have the code be specific to the servlet container. I am unable
to find any description of a change that could possibly cause this, and am
wondering if there is anyone who has encountered this same problem. Am I
missing some setting in my web.xml that would control this? Any help is
greatly appreciated.
thanks!

very slow class loading on initial JSP/servlet request after restart
I've been struggling with a very severe problem on one of my three Tomcat servers since late December. I'm completely stumped. I'm running 6.0.18 on all three servers, which are all running Fedora Core 9, all currently running Sun's JDK 1.6.0_12. The only difference is hardware. The server that's being a problem is a Dell PowerEdge 1950, quad dual core. All three servers are configured exactly the same, with Apache HTTPD and using mod_proxy_ajp to pass requests on to Tomcat's AJP connector. All Tomcat instances are running the tomcat-native APR v1.1.14 that comes bundled with Tomcat. However, this problem persists on the problematic server if I don't run tomcat-native APR. The problem, which spontaneously appeared a few days before Christmas on this one server, is that the initial request of a JSP or servlet takes AGES to respond, usually exceeding several minutes. I've found that compilation of a JSP to a class file is nearly instant, but response from the resulting compiled class takes forever. Further, I found that this only happens when the offending JSP (or servlet) imports classes that I wrote, located in a JAR in Tomcat's /lib directory or inside the web app's WEB-INF/lib directory, or expanded out under WEB-INF/classes. For example, the following simple JSP, <%@ page import="java.util.*, java.io.*, net.ims.jcms.*" %> <% java.util.Date endDate = new java.util.Date(); out.println(endDate.toString()); %> takes AGES to respond, the first time it is requested after a Tomcat restart (even if the compiled class is present under the /work tree), while another JSP with the same executable lines: <%@ page import="java.util.*, java.io.* %> <% java.util.Date endDate = new java.util.Date(); out.println(endDate.toString()); %> responds immediately. The net.ims.jcms package is something I wrote. After the first time a JSP has been requested, subsequent requests respond immediately. So, the server still functions, but there is a horribly long delay before pages respond after a Tomcat restart. Again, this is not a compilation issue; I've monitored the /work directory and can see that the class files appear very quickly. In addition, this problem recurs after a Tomcat restart when the compiled class files already exist under /work. I've run the JVM with the -verbose:class option, and, sure enough, the long delay corresponds to a long delay before the page's class is loaded by the JVM. As soon as the JVM spits out the line saying it loaded the class, the response is sent. So, my conclusion is that the class loader simply takes a very long time, on the first request, if the class imports the package that I wrote. After the class is loaded into memory by that first request, subsequent requests respond normally. I cannot divine any problem with my JAR file or classes within it that would result in this problem; furthermore, it only occurs on one of three servers running the exact same everything. I have run MEMTEST86 on the offending server and memory seems to be fine. It is fine for all other services, processes, etc. The problem is robust on this specific server - it has transcended versions of Tomcat, the JVM, the kernel version, etc. I would greatly appreciate any suggestions for further diagnostics, things to try, offending things I may have done in my Java package, etc. Thanks! - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

The JAR just contains class files for a couple of packages.

And, once the class is loaded (as indicated by the output line from the -verbose:class JVM option) execution is quick.

Re: very slow class loading on initial JSP/servlet request after restart
I'd like to correct an error I made in my earlier report of this problem. It turns out that the response delay in my simple test JSP IS during compilation! I ran stat on the files in question, as well as looked at the time shown on the response page (which is all the test JSP does). (I think I got confused by the output of the -verbose:class JVM option earlier.)

Re: very slow class loading on initial JSP/servlet request after restart
Chuck's comment about JSP to Java translation done by Jasper reminded me that I should have included the time on the Java source file created during JSP compilation. It shows that the Java source file was created immediately, but accessed again six seconds later (!), presumably by the compiler.

Re: very slow class loading on initial JSP/servlet request afterrestart
Actually, /usr/local/tomcat is a symlink to /usr/local/apache-tomcat-6.0.18. But that's a pretty important symlink for me, to make it easy to change Tomcat versions. But I'll investigate that. That's the only symlink involved that I can think of.

Make sure to try both in and outside of Tomcat's work directory and the webapp's directory underneath it. Might be something odd going on with that specific path.

Re: very slow class loading on initial JSP/servlet request after restart
An update. I've written a simple standalone Java routine that calls File.exists(). It never hangs. In fact, I ran it against the class file that Tomcat creates from a test JSP; it doesn't hang, returns false for the (long) time it takes Tomcat to create the class file on the slow system, then returns true after the class file is created (and the HTTP response is sent). I ran my routine as the tomcat user. Since compilation seems to be the issue, I tried replacing Jasper JDT (by removing jasper-jdt.jar from /lib) with Ant (by placing ant.jar in /lib) and restarting Tomcat. This did not improve my problem. JSPs still compile slowly with Ant instead of JDT on the slow machine (and fast on the other machines). I've reverted back to JDT. - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
Re: very slow class loading on initial JSP/servlet request after restart
Thanks, Chris. I ran e2fsck with the -c option, which runs badblocks, when I tested it earlier. And I just ran badblocks again - 0 bad blocks found. I wish I could fix this by simply as swapping out a bad disk (notwithstanding Andre's desire for intellectual pursuits), but I really think it's software, either in some service mucking up the JVM or the JVM itself. But it only manifests itself under Tomcat, and then only when this particular package is imported.

I've seen disks that scan fine contain a growing number of blocks causing read errors and continuous retries. Yeah, you gotta run badblocks on it. fsck just checks the filesystem integrity, not the physical disk. - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

I ran stat on the files in question, as well as looked at the time shown on the response page (which is all the test JSP does). (I think I got confused by the output of the -verbose:class JVM option earlier.) Restarting from the point above.. Leaving the current test jsp page in place, but taking a copy of it under another name, does the symptom then also show up on the copy ? Yes, always. That's how I reproduce it without having to restart the server. I just copy from test1.jsp to test2.jsp, and then test2.jsp takes a long time to compile. It's a very robust problem, with no specific source or compiled files involved. It just requires a JSP that hasn't yet been compiled. The same with the whole webapp, copied under another name. Any web app. There are four running now, I used to have about 8 running on this server, and I've put new web apps on (like yesterday), always reproducing the problem. But all of these web apps import my Java package at the top of the JSPs. Separate question : does this Tomcat, contrary to the others, have the SecurityManager on ? or vice-versa ? No it doesn't. SecurityManager is not on any of the servers. I have not changed catalina.policy, and I do not invoke Tomcat with the -security option. - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

But it only manifests itself under Tomcat, and then only when this particular package is imported. Do you see the same issue if you pre-compile that JSP? Surprisingly, yes. So it's not only a compilation issue. After some individual tests, I compiled the JSPs from the four sites I have running on this server and restarted Tomcat, and the LONG delay before Tomcat begins serving page requests continues. I looked at my individual test JSP, now precompiled, and, sure enough, it takes a long time to respond to the first request after a Tomcat restart. In fact, it wasn't any better than when Tomcat compiles them on the fly. So I'm back to thinking the classloader is involved in this delay as well. I did check, just to be sure, and Tomcat did not write any class files under Catalina/work. And if I deleted a compiled class file on a site, a request throws an error logged in catalina.out. So, Tomcat is definitely using the compiled classes. - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

Juha Laiho wrote: One tool that I haven't yet seen suggested is 'strace', the Linux system call tracer. This will show all the calls your application makes to the operating system. As you say the application is mostly idle during the delay, it is, in one way or another, waiting for some OS service to complete. 'strace' should provide you with timestamped information on what OS services were called, with which arguments, and how long did it take for them to return with results. 'strace' will leave you with a huge file (or a set of huge files, depending on the options you use), and going through them will take some time - but you'll most likely also find what causes the delay. Thanks, Juha. Actually Pieter suggested it a little while ago, and I've been trying to get some information out of strace. The best I can do is to put strace in front of the java command that's inside catalina.sh. That's the command that shows with ps -ef when Tomcat is running. BUT, I get nothing out of strace when I make page requests on a site, it just shows output during Tomcat startup. So, I've not figured out how to get strace to say what the JVM is during the delay. jstack has led us to a stalled File.exists() in one case, but we don't know what file it's looking for. And I'm not convinced that File.exists() is the only method that's stalling. Since this problem exists only on a production server, a server on which I must still serve at least two customer sites (due to DNS issues) in addition to our own and any others I put on there, I'm a bit restricted in terms of how much I can muck with it (not that I haven't brought those live sites down for awkward periods of time with the diagnosis I've attempted so far). I wish I had a test environment on another server that replicates this issue, but my other two servers run Tomcat perfectly fast, and since I don't understand what's causing the problem, I cannot make one of my other servers reproduce it. Another diagnostic problem is that undeploying a context with the Tomcat /manager app, and then starting it again, does NOT reset this problem - the response to a JSP request is immediate (provided it had been requested since the last Tomcat startup). This problem is only reset on a given JSP if I restart Tomcat entirely; I can reproduce it by creating fresh JSPs with new names and requesting them. But, clearly, the key diagnostic issue is finding out WHAT is going on during the delay that a JSP incurs when it is first requested of a given Tomcat instance. I've not been able to find out from strace. I'll give truss -f and truss -ff a try. - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
