Getting rid of the JMS specific fields doesn't preclude the above. It's quite possible that you could write a PersistenceManager implementation that stores headers (whether JMS or not) in a different table where they could be looked at by a human. This would probably be hideously slow, but someone may want it. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4011616#...
