I mean that I have filled the username and password in config-property element as you but I saw that the createConnection doesn't receive them. So it works only if I use QueueConnection queueConnection = queueFactory.createQueueConnection("scott","mypass"); In addition I am trying to use a MDB. Do you have an example of deployment descriptors for it ? View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4211591#...
