Hi

1. I am using openJMS for publishing/subscribing
2. I am able to publish using openJMS example of SimplePublisher.java as independent java classes and through servlet in tomcat.

Problem:
The moment I use the same code in websphere 5.1 I am getting null connections when I call "createTopicConnection". I tried calling the jms related code directly and also through generic JMS provider but everytime the same problem.

The code is as below

TopicConnectionFactory factory = (TopicConnectionFactory)context.lookup("JmsTopicConnectionFactoryNew");
// I am able to get factory

TopicConnection connection = factory.createTopicConnection();
// this line throws exception
The exception is as below:

[5/23/05 18:14:12:350 EDT] 54205420 SystemErr R java.lang.NullPointerException

[5/23/05 18:14:12:380 EDT] 54205420 SystemErr R at java.lang.Throwable.<init>(Throwable.java:54)

[5/23/05 18:14:12:380 EDT] 54205420 SystemErr R at java.lang.Throwable.<init>(Throwable.java:68)

[5/23/05 18:14:12:380 EDT] 54205420 SystemErr R at org.exolab.jms.client.JmsTopicConnectionFactory.createTopicConnection(JmsTopicConnectionFactory.java:115)

[5/23/05 18:14:12:390 EDT] 54205420 SystemErr R at org.exolab.jms.client.JmsTopicConnectionFactory.createTopicConnection(JmsTopicConnectionFactory.java:103)

[5/23/05 18:14:12:390 EDT] 54205420 SystemErr R at openjms.examples.client.console.SimplePublisher.main(SimplePublisher.java)

In the debuger I found the follwing
TopicConnectionFactory factory = (TopicConnectionFactory)
context.lookup("JmsTopicConnectionFactoryNew");

factory is returned but the factory->_connections = null [as
seen in debugger]

Thanks
