What you are doign is - you have local jms server (along with the MDB Container) having components accessing remote JMS Server which is quite alright if you put up with co-existing JMS server. As far as I know, you would do scoping if you wish to have no co-existing JMS Server within you EJBContainer (that is, application server). /Madhu View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3974480#...
