Application doesn't find the library

Hello Together,

i have a problem with the JBoss Server.

I get the following exception:
2009-04-03 12:30:06,102 INFO [STDOUT] 12:30:06,101 ERROR [http-0.0.0.0-50520-3] org.apache.catalina.core.ContainerBase.[jboss.web].[localhost].[/DmMethods].[Do
Method] - Servlet.
service() for servlet DoMethod threw exception
javax.servlet.ServletException: java.lang.Exception: java.lang.NoClassDefFoundError: org.apache.fop.apps.FopFactory

at com.documentum.mthdservlet.DoMethod.doPost(Unknown Source)
at javax.servlet.http.HttpServlet.service(HttpServlet.java:710)
at javax.servlet.http.HttpServlet.service(HttpServlet.java:803)

But the fop_95.jar (with FopFactory.class) is there. See here my StartServer Log von JBoss:

2009-04-02 18:34:22,113 INFO [org.jboss.deployment.EARDeployer]

What can be a reason for the exception?

Can anyone help me?

Thanks in advance.

How is your application packaged? Where is the fop_95.jar file located within that package?

It's a WAR web-application within a EAR folder. It's a "embedded" JBoss Server within the Enterprise Content Management System EMC Documentum.

Now i moved the fop_95.jar to the WEB-INF/lib folder of the web-application. Now it works.

But now i recieve the error message:

java.lang.VerifyError: javax/mail/Part.setDataHandler(Ljavax/activation/DataHandler;)V

Can i trace the classloading in JBoss?

Thanks for your help.

Hmm, should I repeat myself? Why not:

Add the -verbose:class JVM option to the command line. This option causes the JVM to print the JAR file for each class loaded.
