Java EE (Java Enterprise Edition) General Discussion

Hi all,

I have the following problem:

I created and deployed a Session Bean but when I want to call the method the bean is offering I get the following exception:

java.rmi.ServerException: RemoteException occurred in server thread; nested exce

The bean is EventDBSelectionBean and offers the method

public int getEvents() throws RemoteException;

, the remote home interface is called

EventDBSelectionHome

and the remote interface is

EventDBSelectionIF

. Within the same application I implemented and deployed other session beans which wirk perfectly fine.

Has anyone an idea what could be wrong??

Best regards
