[jboss-user] [Messaging, JMS & JBossMQ] - Unable to get Connection to send a message on the testQueue

Hi, I am using JBOSS AS 4.2 GA and JBoss Messaging 1.3 GA.I have created an CRUD application with Seam and database is MySQL.From the entity bean created I am trying to send a message to testQueue on the server.The code from the Stateless session bean messaging example is moved to a utility java class. So I am getting teh following exception when i try to send te message to teh queue looks like its able to create a connection but fails on connection.start :08,042 INFO [STDOUT] Hibernate: insert into
