Pinned topic ClassCastException for incompatible EJB stub.

‏2009-09-17T10:00:32Z |
Hi,
Im getting ClassCastException while invoking the EJB of its own module. This Exception is occuring only in the following case.

1) Application A has EJB E, invoking E from application A works perfectly.
2) Another Application B invokes EJB E of Application A, which is also works perfectly.
3) After performing the above case(Case 2) once again im trying to perform the case 1, which provides the ClassCastException for me.

Please help me to identify what may be the possible cause for this problem.

Note: There is no duplicate copy of Home class(which causes ClassCastException) in both Application A and B.

    Can you post details about the ClassCastException? i.e. the class name + stacktrace?

        Can you upload a simple application that can reproduce your problem?
