I have an entity bean named 'User' (associate with value object UserData)
and a session bean named 'UserCollection' that contains the function 'findById( int id )'.
Whenever I call this function with a valid id, i receive the following exception:
[test] java.rmi.ServerException: RemoteException occurred in server thread;
nested exception is:
[test] java.rmi.ServerException: Load failed; nested exception is:

BTW: in 'log/server.log', the error is not reported, every thing seems fine.
