embedded tomcat classpath setting

[sbv_chris]

Hi, i'm working on a project involving oracle portals and want to use JBoss/Tomcat as a portlet provider. To do this i need to place a few portal jar files in its classpath. I tried updating the startup batch file, place the jar file in jboss_home/lib and also in the WEB-INF/lib folder in the war file. But the embedded tomcat server is unable to locate these jar files and i get a tomcat error complaining the servlet was not found. Is there a way for the embedded tomcat to find these jar files? I'm using JBoss version 3.2RC3

cheers,
sunil.

Put them in server/default/lib
or in jbossweb-tomcat41.sar/

I had put them in server/default/lib directory too. It didn't pick it from there and when i tried to add it in jbossweb-tomcat41.sar, tomcat would not startup any more along with JBoss. Any other way to do this?

[adrian.brock]

Post the details of your problem. What isn't working?
NOT "it does not work".

sorry bout that,

I get the following Tomcat exception (HTTP Status 500)

java.lang.ClassNotFoundException: oracle.webdb.provider.v2.adapter.SOAPServlet

The above class is in the jar file (pdkjava.jar) which is what should be pulled from server/default/lib

[adrian.brock]

And what do you have in the classpath? Don't add anything
there.

Also, please post the full stacktrace if you have it.

Are all the referenced classes in server/default/lib?
If that servlet needs a class from the war it won't work
unless the servlet uses the Thread's context classloader
to load the class.

Regards,
Adrian

All the referenced classes are in server/default/lib(in jar files). I also placed the jar files in the war file's WEB-INF/lib and added a Manifest classpath entry pointing to the jar in the war:
Class-Path: WEB-INF/lib/pdkjava.jar
The above jar has the SOAPServlet class in the right packaging.

The error listing i get:

javax.servlet.ServletException: Wrapper cannot find servlet class oracle.webdb.provider.v2.adapter.SOAPServlet or a class it depends on

I have removed all entries from run.bat so there isn't any more application jar files in jboss' classpath.

[adrian.brock]

Neither of those messages are very informative.
I still think you have a class that is unreachable.

The MANIFEST.MF is irrelevent and wrong.
What is WEB-INF/lib/pdkjava.jar? Classes in
server/default/lib cannot see this.

You've totally confused me now, I have no idea
where you are deploying your classes.

Try setting TRACE on org.jboss.mx.loading
in conf/log4j.xml (you will find examples for other
categories).
Then post the snippet from log/server.log where it
tries to load the class.
This will give me some idea where it is looking
for the class.

Adrian
