Unable to get Connection to send a message on the testQueue

phansaaj Aug 31, 2007 11:15 AM

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 dummy.ticket_master (faultid, faulttype, faultdesc, faultpriority, faultlocation, deviceid, engineer, ticketpriority, ticketstatus, ticketresolution, approvalcomments, ticketid) values (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)
