ClassLoader error loading BIRT within Sybase EAServer 4.2 application server [message #101353]

I am trying to use the Report Engine from within a Java CORBA component in my application server. I continually get this error in
the appserver log when trying to hit the component from a client. The libraries are on the classpath but I still get this error.
If I remove the libraries I get a very short NoClassDefFoundError so I think it is seeing the libraries fine, just can't load them.

Any ideas or suggestions?

Problem solved. For any other EAServer users, all that was required was to add all of the BIRT related jars to the EAServer
java/classes folder and then
reference them in the Java Classes tab of the component properties. Here is the relevant info from the EAServer Programmer's guide:

Is it Jar files in WEB-INF--> Lib folder and class files in
WEB-INF-->Classes folder or do we need to copy all jars also into
web-inf-->Classes?

I was not trying to use BIRT from a web application within EAServer, just as a container for CORBA Java components. I put only the
Jar files in the java/classes folder. Looks like from the docs that EAServer will use them in web applications if they are in the
java/classes folder.
