that's an out of scope question.. it's not even a HornetQ question...
And this will be pretty much debug your application's deployment. I don't think you would get much help on any public user's forum. That's more a conslting gig.
The reason for the post is, this was working absolutely fine in jboss 4.3.GA. But after creating Hornet Queue configuration and deployed ejb-jar.xml & jboss-ejb3.xml configurations, this problem surfaced up.
Anyway will dig this out. Thanks for ur reply though
