I have a stateless session bean which has the methods with Collection as input and output parameters.

So I wrote a wrapper class on the top of this stateless session bean, which calls this stateless
session bean methods and converts the collection params to string[] data types(JAVA-RPC valid datatypes) and
returns to the client.

Now I converted this wrapper class into Webservice. I have used Weblogic application server.
I used:
servicegen ant task to convert java class to web service.

I deployed
1.stateless session bean
2.Wrapper web service class into Weblogic App server 8.1(sp3)

When I tried to access this wrapper WS, I am getting the following exception. This is because my wrapper class is not
able to find the stateless session bean.

javax.servlet.ServletException: Web Service init() failed: java.lang.NoClassDefFoundError: org/ieee/serviceadvisor/Servi

My question:

Since my wrapper webservice class uses stateless session bean, my "ServiceAdvisorWS.ear" webservice ear should include
stateless session bean jar "service_advisor.jar" while generating the webservice using "servicegen".

How do I include dependency jar files while generating webservice ear?

Also do anybody has any examples of wrapper classes for ejbs? or any good site on this topic?

Thank you very much!
