The message, "User null is NOT authenticated," typically indicates a problem with your authentication datasource - either the authentication datasource (specified in <JBOSS_HOME>/server//conf/login-config.xml - application-policy "messaging") is different from JBM's datasource (specified in <JBOSS_HOME>/server//deploy/jboss-messaging.sar/*-persistence-service.xml) or the table JMS_USER doesn't exist or the row in the table whose USER_ID is "guest" doesn't exist. Can you check those things? I hope that makes sense :) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4183032#...
