When you say Singleton I think you really mean "non clustered queue". Singleton is something quite different - it's when you have the queue on only one node of the cluster and is not currently supported by JBM. Regarding your brain storm - I don't think this is a good idea. The idea was to simplify, not make things more complex. KISS principle again. ;) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4170788#...
