Summary: publishing from websphere 5.1

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

Problem:
The moment I use the same code in websphere 5.1 I am
getting null connections when "createTopicConnection"
is called. The exception is as below:

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

Wonder if its a bug?

The following shouldn't make any difference, but not having a
websphere installation, I can't verify.
1. Download and extract the 0.7.6.1 sources
2. Edit src/main/org/exolab/jms/client/JmsConnectionFactory.java
and remove all "transient" keywords.
3. Recompile.

build.bat jar

(Jars willl be created in the lib dir.
See docs/devguide/build.html in the binary distro
for more build instructions)

Looking at the code, I can't see that _connections ever gets set
to null. Are you using 0.7.6.1, or some other version.
The source for JmsConnectionFactory in 0.7.6.1 is here:
http://cvs.sourceforge.net/viewcvs.py/openjms/openjms/src/main/o
rg/exolab/jms/client/Attic/JmsConnectionFactory.java?
rev=1.19&only_with_tag=openjms_0_7_6_maint

To add on the above

Context context = ContextHelper.getContext(cmdline);
returns context, there is a difference in context data [as seen
in debugger]
java.naming.factory.url.pkgs=:com.ibm.ws.naming:com.ibm.w
s.naming:com.ibm.ws.naming} is also there in context-

myprops

This ..url.pkgs is not there at all when class is executed
independently. I removed this property but still the exception,
also dont know if this makes the problem

also when following is executed
TopicConnectionFactory factory = (TopicConnectionFactory)
context.lookup("JmsTopicConnectionFactoryNew");

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

I am not able to find any document which specify the different
usage in websphere.
