Hi, I downloaded jboss-4.2.1.GA.zip as my JBoss AS, but it seems it doesn't have JMS provider, because when I tried to deploy my JBossESB to it, it complains "can't determine JMS provider". I thought there should be a default JMS provider in Jboss 4..2.1? If not, how could I add JMS provider to my Jboss AS? Is the default one Jboss MQ? If yes, I need to convert JBoss MQ to use JBoss Message? I am confused... Thanks a lot for clarification!!
