    JMS in AS7

    Glen Miller Newbie

      This used to work in AS6  -- I have tried to modify things to work in AS7, but can't quite get it working.  I am not getting any exceptions, but the messages are not being sent or maybe they are and not being delivered to the message bean.

      Any Ideas of what to try next?

       

      I am using AS7 running:

      ./standalone.sh --server-config=standalone-preview.xml

       

       

      standalone-preview.xml  -- parts

       

                  <jms-destinations>

                      <jms-queue name="stock_market_service_tick_queue">

                          <entry name="queue/stock_market_service_tick_queue"/>

                      </jms-queue>

                  </jms-destinations>

          As I know message driven beans with JMS do not yet work with JBoss 7, it will be supported in JBoss 7.1. So you should wait for a nightly build that supports MDB with JMS or build a workaround with a singleton stateful bean as message listener.

            Hello Glen,

             

            you may also consider to take a look at the Seam 3 Framework. The JMS module provides a nice way to bridge between JMS-Messages and CDI-Events. But keep in mind, that currently not all is finished (Currently its 3.0.0.CR1), e.g. ... :

             

            "The default location of ConnectionFactory URL or JNDI name Seam JMS uses; it is hardcoded asConnectionFactory. That being said, if you're testing with Glassfish V3 you should define aConnectionFactory by that name as follows. Thanks Dan Allen for this tip:"

             

            You can spend some hours on this if you have to find it out the hard way ;-)
