I couldn't replicate your issue. However I had to add the acceptors and connectors at the config. I have used this configuration here instead (which just have the netty and in-vm acceptors and connectors: http://anonsvn.jboss.org/repos/messaging/trunk/examples/javaee/mdb/server... Also.. you don't need to narrow anything on the lookup. And since you are on the application server, you don't need also to use properties. You could do just: jndiContext = new InitialContext(); | | logger.debug("Looking up ConnectionFactory..."); | connectionFactory = (ConnectionFactory) | jndiContext.lookup(CONNECTION_FACTORY); | | logger.debug("Looking up test queue..."); | testQueue = (Queue) | jndiContext.lookup(TEST_QUEUE); | (But I had tested without these changes also, and I couldn't replicate). Also.. you should probably use the JCA connection factory inside the application server. you are currently using /ConnectionFactory. And all this ran really fast. I will close as can't replicate for now.. if you provide more data on replicating we can reopen it. View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4242272#...
