    Jboss MQ ConnectionFactory being returned null

    Prashant Sehgal Newbie

      Hi,

      My connection factory is setup in my Jboss 4.0.4 server like this:


      <tx-connection-factory>
      <jndi-name>jms/queue/ControlConnectionFactory</jndi-name>
      <use-java-context>false</use-java-context>
      <xa-transaction/>
      <rar-name>jms-ra.rar</rar-name>
      <connection-definition>org.jboss.resource.adapter.jms.JmsConnectionFactory</connection-definition>
      <config-property name="SessionDefaultType" type="java.lang.String">javax.jms.Topic</config-property>
      <config-property name="JmsProviderAdapterJNDI" type="java.lang.String">java:/DefaultJMSProvider</config-property>
      <max-pool-size>100</max-pool-size>
      </tx-connection-factory>
      



      I'm accessing this from outside of Jboss, using a stand alone client with from it's main method like so:


      public void initializeListener ()
      {
       String url = "lonrs03004:1099";
       Properties props = new Properties();
       props.setProperty("java.naming.factory.initial","org.jnp.interfaces.NamingContextFactory");
       props.setProperty("java.naming.factory.url.pkgs", "org.jboss.naming");
       props.setProperty("java.naming.provider.url", url);
      
       try {
       Context ctx = new InitialContext(props);
       QueueConnectionFactory qConFactory =
       (QueueConnectionFactory) ctx.lookup("jms/queue/ControlConnectionFactory");
      
       if(qConFactory == null) {
       System.out.println("qConFactory is null ");
       System.exit(0);
       }
      }
      



      The connection factory is being returned as null. I read somewhere that this might be because my connection factory is setup using jboss-ra and in such cases standalone clients cant access connection factories. One needs to access them from inside the server.

      a) Is this correct?
      b) If I want to retain my stand-alone client, how should I setup my connection factories?

      Thanks,
      Prashant.

          Also, if I try to retrieve the default ConnectionFactory from my standalone client, it throws the following exception:
