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.
