Hi, We have several listeners (each with a different selector) for the same Topic. The order of the messages per each listener (we need FIFO) is very important for us. We understand that after connection failure, the "failure recovery" mechanism does not guarantee ordering of messages. So we would like to identify "out of order" messages by tracking non-sequantial Message Ids. However this only makes sense if each listener (different selectors remember?) has it's own messageId. Is it possible to get a MessageId per listener? thanks Assaf View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4115322#...
