Java EE (Java Enterprise Edition) General Discussion

I am trying to implement a stand-alone client (without any IBM products installed) to Websphere MQ JMS, using SUN JRE. I tried to follow the instructions as specified in Portable Client Toolkit (from IBM) but run in to problems (see below). If i use the IBM JVM (which doesnt need the ORBs to be specified while invoking JVM) everything works fine. If anyone has implemented such a client, especially one that uses SUN JRE, may i know the steps used? As in, did you have to install a MQ Client on the Client machine, the classpath, properties used, what context factory was used, how the JNDI was setup on the server etc.

Thanks in advance.

Problem:
-----------
Code:
Context context = new InitialContext();
System.out.println("!!! Initial Context obtained:"+context.toString());
QueueConnectionFactory qcf = (QueueConnectionFactory)context.lookup("jms/qcf");
System.out.println("!!! QueueConnectionFactory obtained:"+qcf.toString());
QueueConnection qc = qcf.createQueueConnection();
QueueSession qs = qc.createQueueSession(false, Session.AUTO_ACKNOWLEDGE);
Queue q = (Queue)context.lookup("jms/q");
