Hi, I am newbie on JBossMQ, sorry if my questions seem trivial. First I am looking for MDB code samples who creates dynamically a new topic and place a text message inside. After that, do you know how many topics can a medium size JBoss AS supports? Finally what method a consummer should invoke in order to definitly empty a topic? Thanks for all answers.

Then set the "DestinationManager" on it, and call "start" on it. This can be done remotely as well. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4127441#...
