Hi Anders. Sorry for not responding to the original post. So wrt the ScheduledListeners, I think the way to make them clusterable is by making the underlying Quartz schedule jobs clusterable. I already created a JIRA for this... JBESB-1646. As far as the other transports are concerned... JMS Queues are clustered by nature if you configure the destinations and the JMS providers properly. HTTP endpoints... a load balancer FTP etc... then you might be into a shared cash type solution ala your JGroups suggestion View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4144161#...
