Sorry my bad...the JMSRouter cannot be used in such a situation. The way we are currently doing this is using the jms-jca-provider to have a global transaction for an action pipeline. So the message acknowledgement is handled by the commit of the transaction. If we rollback the transaction the message will be redelivered. But this only handles the incoming message. Not the part of sending out. /Daniel View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4139367#...
