      hi all,
      I am using jboss 4.0.2(also tried 4.0.3sp1).I have a sesion bean with both home and remote interface.After lookingup the local interface , i try to call create on that local proxy object.

      As i call create, the stack trace that is thrown is as following,


      java.rmi.ServerException: EJBException:; nested exception is:
      javax.ejb.EJBException: Could not instantiate bean; CausedByException is:
