    Isolated EJB2 Access from a Client - Jboss 4.3 EAP

      Hi..

       

      I have a task to Isolate Class libraries between 2 Enterprise Application A.ear and B.ear.  B EJB requires to Access A's Remote EJB, but it is throwing exception. But calling A's client to call A's ejb does not have a problem.What am I missing? The failure is very very odd because it is saying ClassNotfound for an object in B while B is accessing EJB in A. The class is in B's lib directory. Stacktrace below:
