[jboss-user] [JBoss Messaging Users] - enableOrderingGroup() not available inside ejb3 Bean an JmsX

[mclu]

Hi!

Any hint on this?

I testest OrderingGroup on 1.4.5 (build 7766) with a client like this:

  | Connection connection = getConnection();
  |         Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
  |         JBossMessageProducer sender = (JBossMessageProducer) session.createProducer(queue);
  |         sender.enableOrderingGroup("Group1");
  | 

The Connection Factory is fetched using
  
  | Hashtable<String, String> env = new Hashtable<String, String>();
  |         env.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
  |         env.put(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces");
  |         env.put(Context.PROVIDER_URL, "localhost:22099");
  | 
  |         InitialContext ic = new InitialContext(env);
  |         cf = (ConnectionFactory) ic.lookup("ConnectionFactory");
  |         queue = (Queue) ic.lookup("/queue/testQueue");
  |         ic.close();
  | 

It works perfect.
Now I want to migrate this to my ejb3 beans which sends messages but uses transactions.
I am using:

  | @Resource(mappedName="java:/JmsXA")
  | private ConnectionFactory cf;
  | 
  | ...
  | 
  | Connection connection = cf.createConnection();
  | connection.start();
  | 
  | Session session = connection.createSession(true, Session.SESSION_TRANSACTED);
  |         JBossMessageProducer sender = (JBossMessageProducer) session.createProducer(queue);
  |         sender.enableOrderingGroup("Group1");
  | 
  | 

This gives a class cast exception because createProducer returns
org.jboss.resource.adapter.jms.JmsMessageProducer and not JBossMessageProducer. The JBossMessageProducer is part of JmsMessageProducer but I can not get it.
I want to use more than one ordering group so it would be nice to be able to set it via the producer.

Any hint how I can handle it with transaction support?
At pdf Userguide page 21 it says regarding JmsXA
"JMS XA Resource adapter, use this to get transacted JMS in beans"
