Hi Tim, I'm a collegue of Egomet (my name is Mirco) and I'm working on the same task of Egomet. In the next weeks I will study how to patch JBoss/HornetQ to obtain the ordered redelivery using a special configuration to avoid multithreading problems. If you are interested to our solution I will send the patch (using the right procedure) for the commit. We found a solution using JBoss 4.0.2 but now we want to upgrade the AS so I would like to insert it in the head line of the sources. Thanks for your time.
