We have deployed Seam applications on JBoss AS 5. In fact, being able to run the booking app is (was?) one of the JBoss 5 tests. However, that being said, JBoss 5 is still very beta. I would not recommend using it as a primary development platform yet. I think it should be ok for dev in a month or two.
What is the problem you are seeing with JBoss 5?
Thanks for the reply. Since the problem I found so far is related to library, I shall put it under the same topic I created before http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3993243.
Thanks in advance
