Hi, Reinitialising all the listeners even when nothing is changed in the config can't be done I think. This even means the listeners are down for the time the reinit process takes. In my opinion we should be able to check whether the config has changed for a certain listener. Is yes we reinitialise this listener. If not we don't do anything. Regarding the threading. Every message coming to a listener results in spawning a new thread to be usedto execute the action. We should implement a thread pool using the concurrancy features in JDK 1.5(Executors). I think we should have a threadpool for each listener. If so we can tune the pool per listener. Listeners/actions taking lot of time to execute can get a bigger threadpool than others. I think this is not that much work. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3975610#...
