We are calling the stopDelivery method on the EJB3 MDB MBean - I believe this one is the container registered when deploying the MDB. The stopDelivery functionality was only re-introduced recently (I believe maybe 1.1.2/1.1.3?) and we have been keen to make use of it. Thanks for the reply and the continuing help :) Cheers P View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4234506#...
