Hi,
JBoss Messageing 1.4.5.GA still doesn't support strict ordering on Topic. And JBM is in maintenance mode only. HornetQ is the better solution for you. As far as I know, HornetQ support strict ordering on Queue, not sure about topic. You can go to the HornetQ forum to discuss your request. The HornetQ forum is very active and you will sure get response from core developers.
