Hi Paul
I had the same issue with JBoss 3.2.6, I remember there was a bug logged
for the issue (just can't recall where :) ) I will look further if you like.
Solution for us is to restart JBoss every time we deploy our Axis
application.
Cheers

Ok guys, I think I'm officially stumped. Here is the senario:
1. I have a web application running in JBoss 3.2.6 (Tomcat 5).
2. My web app calls a web service (using the Axis 1.2 client).
3. The call succeeds.
4. I redeploy the war.
5. The web service call fails with a NullPointerException in JBoss'
UnifiedClassLoader.
Please see the partial stack trace below. You will my classes are
prefixed by "santam.*". The last position in my code is on a statement
"service = new Service();".
Does anybody have any suggestions. I've spent the day searching on the
web, but to no avail.
Regards
Paul
