When I deploy the beans, I get one of the warning.

08:10:11,422 INFO [EJBDeployer]
Bean : TheTroubleTicket
Method : public abstract Person getSubmitter() throws RemoteException
Section: 9.2.7
Warning: The method return values in the remote interface must be of valid types for RMI/IIOP.

Here the Person is nothning but another bean.
If a bean has to implement Seralizable!!!! is that possible!! or do I have to change the design ?... which is not feasible in our porting project...
can any one clarify...
