Hi Clebert, Yes, I agree, this is not a good (neither portable) design, but it's one of the options we are considering for now, mainly for 2 reasons (given our whole context): it might be the easiest to implement and the one with best performance. Other options would be to check the domain before the message is sent (so if the throughput to that domain is too high we could return the JMS message to the queue) or to do this kind of sorting before adding the message to the queue. Anyway, do you think that's possible? -- Felipe View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3989815#...
