[jboss-dev-forums] [JBoss Remoting Development] - Isolated EJB2 Access from a Client - Jboss 4.3 EAP

Rodel Talampas [https://community.jboss.org/people/limacon] created the discussion "Isolated EJB2 Access from a Client - Jboss 4.3 EAP" To view the discussion, visit: https://community.jboss.org/message/823582#823582 -------------------------------------------------------------- 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.
