Hello, This could be a very basic question related to JMS, so I apologize for that in advance. I see that StartListener class is message listener on default incoming queue A. So if 100 concurrent requests come in, 100 listeners start running processes? Are these message listeners pooled? I have seen that kind of configuration on MDBs but not on message listeners. Thanks, Meghana View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4156788#... Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&a...
