Why is my JNDI lookup for a QueueConnectionFactory returning null?

Question

I am trying to look up a QueueConnectionFactory and Queue via Geronimo's JNDI. The Queue gets returned fine, but the QueueConnectionFactory lookup always returns null. It doesn't throw a NamingException, which is what I'd expect if the JNDI name was incorrect.

Can anyone see what I'm doing wrong? The test code below outputs:

true
false

import javax.jms.Queue;
import javax.jms.QueueConnectionFactory;
import javax.naming.InitialContext;
import javax.naming.NamingException;

public class JndiTest
{
    private final static String QUEUE_NAME = "jca:/org.apache.geronimo.configs/activemq-ra/JCAAdminObject/SendReceiveQueue";
    private final static String FACTORY_NAME = "jca:/org.apache.geronimo.configs/activemq-ra/JCAManagedConnectionFactory/DefaultActiveMQConnectionFactory";

    public static void main(String[] args) throws NamingException
    {
     InitialContext ctx = new InitialContext();
     QueueConnectionFactory factory = (QueueConnectionFactory) ctx.lookup(FACTORY_NAME);
     Queue queue = (Queue)ctx.lookup(QUEUE_NAME);
     System.out.println(factory == null);
     System.out.println(queue == null);  
    }

}

In case it makes a difference: I've added openejb-client-3.0.1.jar, geronimo-ejb_3.0_spec-1.0.1.jar and activemq-core-4.1.2-G20090207.jar to my class path, and my jndi.properties file has the properties:

java.naming.factory.initial = org.apache.openejb.client.RemoteInitialContextFactory
java.naming.provider.url = ejbd://127.0.0.1:4201

Answer 1

There's two participants here, you're looking in JNDI for something. Somebody else had to put it there. I don't know the specifics of your environment but my approach to such problems is

• explore the namespace - what's there? Do you have any JNDI browing tools?
• look carfeully in the logs for the service that is supposed to be registering with JNDI, does it report any errors?
