JBoss Messaging 2.0.0 became HornetQ 2.0 a while ago. One of the reason for re-naming is that the JBoss Messaging 2.0.0 is so much different from, and has so many more features than its predecessor JBoss Messaging 1.4.x.
If you're already using JBoss Messaging 2.0.0 beta 4, it should be easy to move to HornetQ. HornetQ inherites the code base from 2.0.0. Only the package has been renamed and more bug fixes.
Any questions you can put to the forum http://community.jboss.org/en/hornetq?view=discussions&start=0
Thank you very much.
Yes, We are using JBoss Messaging2.0.0.BETA4.
It seems that we have no choice but to use HornetQ.
Thank you for your reply.
