Reading the specs I tend to agree. They are so limited. No things like: - number of retries - retry interval What other specs are those in? I am starting to hate the ws-hell (no offence to you guys) and long back to the x.400 or the best, ebXML-MS specs... those were 'clean'. If these other parts come in, it becomes a REAL messaging system. JMS implementations lack a lot of functionality to on this part, regarding retries sequences etc... but for the basic ws-rm (rx) it might be sufficient IF all other AS' support the same subset as JBossMQ/Messaging To be continued View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4026316#...
