Interface MessageDrivenBean

All Superinterfaces:

public interface MessageDrivenBean
extends EnterpriseBean

The MessageDrivenBean interface defines methods that the EJB container uses to notify a message driven bean instance of the instance's life cycle events.

As of EJB 3.0 it is no longer required that a message driven bean class implement this interface.

Since:

EJB 2.0
