Hi

I am using WebSphere Application Server 6 and configured the default message queue and tested the JNDI entries using dumpNameSpace.

While executing the following code.

Hashtable env=new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY,"com.ibm.websphere.naming.WsnInitialContextFactory");
env.put(Context.PROVIDER_URL,"iiop://localhost:2809");
InitialContext jndiContext = new InitialContext(env);
>>Object obj=jndiContext.lookup("jms/ConnectionFactory");
ConnectionFactory factory =(ConnectionFactory)PortableRemoteObject.narrow(obj,ConnectionFactory.class);

I am getting the following exception in the Connectionfactory lookup

javax.naming.NamingException: Failed to initialize the ORB [Root exception is java.lang.ClassCastException]
at com.ibm.ws.naming.util.Helpers.getOrb(Helpers.java:294)

Can anybody say what is the problem ?
