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.
