Can't you implement the Persistence for a specific message type (JMS, AMQP,etc) as a strategy in the Persistence Manager and then you can have a custom schema per message type implementation. So as you add support for different messaging systems you just add a persistence strategy for it. Just a thought, might be maintenance hell though. --Aaron View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4011749#...
