ConnectionFactory lookup

[cfg123]

hi all,
When i want to lookup the QueueConnectionFactory in my program, no any exception shown. But the QueueConnectionFactory i get is in null value. Can anybody help me. Is there still any setting i need to do?

QueueConnectionFactory queueFactory =
(QueueConnectionFactory)context.lookup("ConnectionFactory");

not sure. What context are you using? Is this in jboss or an external client?

[cfg123]

sorry, this is the context used in my program....

System.setProperty("java.naming.factory.initial", "org.jnp.interfaces.NamingContextFactory");
System.setProperty("java.naming.provider.url", "192.90.1.19:1099");

Context context = new InitialContext();
QueueConnectionFactory queueFactory =(QueueConnectionFactory)context.lookup(factoryJNDI);

Sorry, the context i used here is just a normal context in jboss. The program is like this:

System.setProperty("java.naming.factory.initial", "org.jnp.interfaces.NamingContextFactory");
System.setProperty("java.naming.provider.url", "192.90.1.19:1099");

Context context = new InitialContext();
QueueConnectionFactory queueFactory =(QueueConnectionFactory)context.lookup("ConnectionFactory");

Hi!

I have the same problem under jboss 2.4.8 and above.
But under 2.4.4 external client works..

try this
props.put("java.naming.rmi.security.manager", "yes");
props.put(Context.URL_PKG_PREFIXES, "org.jboss.naming");

We had the exact same problem not so long ago on one of my programmer's pc. It was fix by removing some conflicting jars from our classpath. Internally it was producing a marchaling error and for some reason the generated stub didn't complain about it and simply returned null.

Hope this will fix your problem as it did for us!
