Within the onMessage() of the MDB there are 2 stateless session beans which are called. These session beans are never removed from the memory even after the onMessage() has finished execution.

Here is the scenario: I have 2 beans StatefulCounter and StatelessCounter, they have the exact same code except for the name.

37. [EJB3] Stateless Session Bean & Inheritance

Hi, you can safely remove the Stateless annotation in the abstract class. Inheritance will provide you with the functionality of the parent class but it doesn't need to be an EJB.
