Can different clients access one same stateful session bean? 2003-10-18 - By Le Quang Tu
Back
If a client-invoked business method is in progress on an instance when
another client-invoked call, from the same or different client, arrives at
the same instance of a tateful session bean class, the container may throw
the java.rmi.RemoteException  to the second client[4], if the client is a
remote client, or the javax.ejb.EJBException , if the client is a local
client. (from EJB spec )
And the message from Exception is: SessionBean is executing another request.
