often we have two cases: - do something for the depends on a timestamp from data (e.g. warning of a meeting in calendar) - start some checks for administrativ issues (cleaning or statistics ...) In the first case the entity manage the timer (it's easy) In the second case an administrator manage it. I create the Timer with a client (WEB or rich) with an administration console. But I think you can do it whit an mbean for JBoss as well. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3960345#...
