Hello there! I'm running JBoss 4.2.1 and I have this class inheritance:

public abstract class AbstractMDB implements MessageListener{
 @EJB
 private bizRef;

 public abstract void operateMessage(Element message);

 public void onMessage(Message message){
 bizRef.someMethod();
 //create the element
 operateMessage(element);
 }

}
@MessageDriven( activationConfig={
 @ActivationConfigProperty(propertyName="destinationType",propertyValue="javax.jms.Queue"),
 @ActivationConfigProperty(propertyName="destination", propertyValue="queue/QueueA"),
 @ActivationConfigProperty(propertyName="messagingType", propertyValue="javax.jms.MessageListener")

 })
public class ConcreteMDB1 extends AbstractMDB{
 public void operateMessage(Element message){

 }
}

Problem is that this code does not deploy :(

It throws a "unable to determine messagingType interface for MDB"

Is there a way to have an MDB that does not directly implements the MessageListener Interface? Could it be done according to the spec?

Regards
