There is no need to setup a $CLASSPATH for Tomcat.
Tomcat (and most other web containers) don't rely the classpath as set as
an environment variable or on the commandline. They use:
1/ the JARs in the webapp's WEB-INF/lib and bare class files in
WEB-INF/classes
2/ some container-specific hierarchy of classloaders, usually in a
chain-of-responsibility pattern. Tomcat uses
{Tomcat install}/common/lib
{Tomcat install}/common/classes
{Tomcat install}/shared/lib
{Tomcat install}/shared/classes
{Tomcat install}/server/lib
{Tomcat install}/server/classes
(though probably not in that order ;)
Long story short: if you use the container's (and the spec's) method of
making classes available, there should be no need to set a classpath.
The problem you've experience is because you've hacked the classpath
Tomcat searches. Start with a clean install, and follow the proper
procedure for making classes available.

1/ root directory and document root are terms that don't 100% apply
in the J2EE world. Use the term context path, because a webapp
(context) may exist in a directory or inside a WAR file.
So, the context path defaults to one of

{value of appBase}/{WAR file}
where the value of appBase defaults to {Tomcat install}/webapps.

2/ tell Apache to serve the static content and let Tomcat handle the
Java
A slight twist on #1, you could setup Apache with a separate document
root and copy all static content there. This has the added benefit that
Java code never touches the web server (should you separate the web/app
servers) but will require some fancy script work if the app is not
organized by content, i.e.
{context}
|
+- jsp/
|
+- images/
|
+- html/
... and so on.

Tomcat (and most other web containers) don't use the classpath as set as
an environment variable or on the commandline. They use
1/ the JARs in the webapp's WEB-INF/lib and bare class files in
WEB-INF/classes
2/ some container-specific hierarchy of classloaders, usually in a
chain-of-responsibility pattern. Tomcat uses
{Tomcat install}/common/lib
{Tomcat install}/common/classes
{Tomcat install}/shared/lib
{Tomcat install}/shared/classes
{Tomcat install}/server/lib
{Tomcat install}/server/classes
(though probably not in that order ;)
Long story short: if you use the container's (and the spec's) method of
making classes available, there should be no need to set a classpath.
Make your one other entry available in one of the places mentioned
above.

There's more to recognizing user info than just passwd and shadow; apps
these days make calls through system libraries rather than process those
files directly.
Start with {chroot}/etc/nsswitch.conf: what's in there? In turn, the
calls that load nsswitch.conf will likely involve a trip through the
resolver libraries (/lib/libnss_*)... You could start there and see what
else comes up.
I've found it invaluable to (temporarily) install strace under the
chroot area to see what files programs try to open behind the scenes.

You can't beat Tomcat's price. WL licensing is based on the number of CPUs in the machine. (Doesn't sound too bad until you have 40+ CPUs involved. ;) 2/ Spec compliance/upkeep: Tomcat 5.x implements servlet spec 2.4, while (IIRC) Weblogic 8.1 is still 2.3. Granted, BEA has several reasons to take the Corporate slow and steady Pace; but it's nice that I can use the servlet 2.4/JSP 2.0 features *now* instead of waiting. 3/ Clustering: Weblogic wins here, not so much because WL clustering is any better but because it's been tried and tested. I've been using WL clusters for more than 4 years now, since v5.1. By comparison, Tomcat clustering appeared in v5.0 (last year, was it?) so it hasn't experienced nearly as much road-testing. 4/ Webserver connectivity: I've never had a problem with mod_jk; but based on list posts, I'm the pathological case. (The ratio of jk flaws vs pilot error is beyond me.) Setting up the Weblogic Proxy Plugin was a complete no-brainer, vs mod_jk which was a partial no_brainer. 5/ All-In-One package: What are your long-term app dev goals? WL provides EJB and other features out of the box. As others have mentioned, doing that with Tomcat involves adding other products to the mix, which can slow down a pre-product RD effort. 6/ Hand-holding: for a fee, BEA can send a pro-serv team to your site and/or provide training. There is no official (Apache-based) Tomcat consulting/pro-serv, as far as I know. While unofficial services are certainly available, you'd have to shop around, check credentials, etc. That said, don't let the open source vs vended labels fool you. The support models aren't too different as long as you don't deviate too far from the norm with your app/setup, and you're conservative about upgrades. What you really have to worry about is in it for the long run vs fly-by-night; and neither Tomcat nor Weblogic show any signs of disappearing for the forseeable future. -QM -- software -- http://www.brandxdev.net tech news -- http://www.RoarNetworX.com - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Has anything changed there w/r/t ResourceBundles and I18N? Doubtful, but worth a look. I know my apps running under Tomcat 5.0.28 / JDK 1.4.x don't have this problem.

Don't quote me on this, but IIRC there is a separate classloader for compiled JSPs to help with GC due to the fact that a classloader can't be GC'd until all classes it owns have been GC'd. Remember, though, Tomcat (and other containers) stack certain classloaders for a Chain-of-Responsibility pattern effect. Really, I'm at a loss for why it wouldn't work for you, outside of the fact that you're using Tomcat 5.5 and JDK 1.5. As a quick test, what about loading *any* data out of the class?

Tracking down missing symbols can be a pain, especially if you didn't compile everything yourself from source. It could be as simple as a missing dir in LD_LIBRARY_PATH (especially since the Tomcat user's environment may not the same as the build-user's environment), or something as nasty as subtle linking problem. Run ldd on mod_jk2.so to see what libs it needs, then run nm on those libraries to see which one defines __divdi3. -QM -- software -- http://www.brandxdev.net tech news -- http://www.RoarNetworX.com - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: tomcat5 using jsvc in a chroot jail

The system's looking for a file named .hotspot_compiler in the current
dir. The java command may internally change dirs, though, so you'll
have to do some more work to figure out where current dir is.
If the process hangs, you can check its /proc/{pid} entry for that info
and more.
That, and dump strace's output to a file so you can grep for other
occurences of .hotspot_compiler... Maybe it's failing to create a file
somewhere.
How did you copy/install the JDK? You'd catch all of the hidden files
if you were to tar it up and ship it over.

Don't applaud; just throw money. ;)

Instead of WEB-INF, make that META-INF. -but that's if the context XML

I would say, doing any sort of thread work inside the container is asking for odd behavior. As for stopping the thread before invalidating a session, how will you control that? You could perform this action as part of the general logout page, but what about people who simply let the sessions time out? -QM -- software -- http://www.brandxdev.net tech news -- http://www.RoarNetworX.com - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
