Get null topic connectionfatory from jboss jndi

[wallace]

I am following the instruction on
http://devzone.logicblaze.com/site/integrating-apache-activemq-with-jboss.html
to integrate jboss4.0.5/activemq4.0.

I have a problem with looking up connection factory with remote jboss jndi
access.
I have this in –ds.xml

   <tx-connection-factory> 
      <jndi-name>testing/TopicConnectionFactory</jndi-name> 
      <use-java-context>false</use-java-context>   
      <xa-transaction/> 
      <track-connection-by-tx/> 
      <rar-name>activemq-ra.rar</rar-name> 
     
<connection-definition>javax.jms.TopicConnectionFactory</connection-definition> 
      <ServerUrl>vm://localhost</ServerUrl> 
      <min-pool-size>1</min-pool-size> 
      <max-pool-size>200</max-pool-size> 
      <blocking-timeout-millis>30000</blocking-timeout-millis> 
      <idle-timeout-minutes>3</idle-timeout-minutes> 
   </tx-connection-factory>

I tried to look up the connection factory with code.
        try { 
           Properties env2 = new Properties();
         
           env2.put(Context.INITIAL_CONTEXT_FACTORY,
"org.jnp.interfaces.NamingContextFactory");
           env2.put(Context.PROVIDER_URL, "jnp://localhost:1099");
           InitialContext jndiContext = new InitialContext(env2);       

            // print the binding info
            NamingEnumeration<NameClassPair> namingEnum =
jndiContext.list("testing"); 
             while (namingEnum.hasMore()) { 
              NameClassPair nameClassPair = namingEnum.next(); 
              System.out.println("Name: " + nameClassPair.getName() + " ,
Class: " + nameClassPair.getClassName() ); 
            }
            ref = jndiContext.lookup("testing/TopicConnectionFactory"); 
            System.out.println("ref is null:" + (ref==null)); 
            TopicConnectionFactory tFactory = (TopicConnectionFactory)
PortableRemoteObject 
                    .narrow(ref, TopicConnectionFactory.class); 
        } catch (NameNotFoundException e) { 
            e.printStackTrace(); 
        }


I got the following print out:

Name: JVTEventTopic , Class: org.apache.activemq.command.ActiveMQTopic 
Name: QueueConnectionFactory , Class:
org.apache.activemq.ra.ActiveMQConnectionFactory 
Name: TopicConnectionFactory , Class:
org.apache.activemq.ra.ActiveMQConnectionFactory 
Name: MessageQueue , Class: org.apache.activemq.command.ActiveMQQueue 
Name: XVTEventTopic , Class: org.apache.activemq.command.ActiveMQTopic

ref is null

 
Note that I did NOT get any NameNotFoundException and the print out actually
shows that the binding is correct. So why would I get null when I tried to
lookup "testing/TopicConnectionFactory"?
I have the activemq-ra-4.0.2.jar file in the <jboss>/server/default/lib
directory.

And I want to configure the topic connection factory with ra.xml, so I
cannot use activemq jndi.

Thanks,
-Wallace
