There's a third problem with your code: You start the subscriber thread, then immediately start the publisher thread(s) before waiting for the subcriber thread to finish. This means there's a strong possibility you'll start sending messages before the durable subscription is created, so messages will be "lost". Much as I would like to debug your code all day, I have to get back to work now ;) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4168656#...
