Summary: NPE thrown from openJms connectionFactory class

Initial Comment:
Hi All,

I am trying to subscribe to a topic from a web app 
running on Websphere App server (WAS) 4.0 server. The 
connectionFactory and Topic setup in WAS 4.0 jndi 
namespace point correctly to corresponding objects 
created in openJms. The lookup of factory and topic 
works fine, but when I try to get the connection from 
the factory I get a NPE thrown from opneJms classes.

When I directly access openJms jndi namespace, lookup 
the connectionFactory and call the 
createTopicConnection() method, I still get the NPE.

Can someone help please. This is very urgent.

Here is the code:

public TopicConnection connection = null;
  try {
         connection = 
connectionFactory.createTopicConnection();
…..
        }

Here is part of stack trace:
(JmsMultiTopicReceiverServlet is the servlet I am using 
to make the connection)

[7/1/04 22:15:39:593 EDT] 6b586b58 WebGroup      X

Thanks.
Any help is greatly appreciated.

What version of OpenJMS are you using? 
Looking at the source for 0.7.6.1 (see 
http://openjms.sourceforge.net/xref/org/exolab/jms/client/J
msConnectionFactory.html), its not clear how an NPE could 
be raised.
