I am currently working with JBoss 3.0.8. My application has a stateless session 
EJB that performs a DB update and sends a JMS message. I want the DB update and 
JMS message send to be managed in the same JTA transaction context. The EJB is 
using a container managed transaction.

The J2EE 1.3 spec isn't very clear about how this works with managed 
transactions, but according to the Sun tutorial at 
http://java.sun.com/products/jms/tutorial/1_3_1-fcs/doc/j2eeapp2.html, the 
container should manage the JMS transaction if the session is creating using 
this call:

session = connection.createQueueSession(true, 0);

The call to session.commit() should be unnecessary since the container manages 
the transaction.

However, when I try this from JBoss it appears the JMS transaction is never 
committed and therfore the message is never sent. If I instead use 
connection.createQueueSession(false, QueueSession.AUTO_ACKNOWLEDGE) then I run 
into the problem where the JMS message is immediately commited independent of 
the session EJB transaction. Depending on timing the message receiver may 
attempt to process the message before the session EJB's transaction has 
committed, which is a problem since the receiver needs that data.

Can anyone provide any hints on how to get JBoss to coordinate the JMS 
transaction as part of the session EJB transaction when sending a message from 
a session EJB?

Thanks,
