I can't see any reason why a session bean cannot do b). The way I understand it
a session bean could easily do the following:
1. Get X nr of JMS queues/topics
2. Send messages to the queues/topics
3. Do receive() on each of the X queues/topics
4. Compute result and return once all receive()'s have completed
Why do you say this is not possible?
