NullPointerException redeploying AxisServlet on JBoss 4.0.3R

[genman]

This is when reloading a servet inside of a .war file, inside a .ear file. The axis 1.2 jar files are in $JBOSS_DIST/server/default/lib. I'm not sure this is a problem with Axis or JBoss. (I don't have this problem on JBoss 3.2, but I'm using an older Axis dist. as well.)

Thanks.

If somebody can't help out, I guess I should probably file as a bug.

Thanks.

I had the same problem when I copied the axis jar -files to server/default/lib. The Axis classloader can't recover from redeployment, because it has static classloaders.

The problem can be avoided by copying the Axis jars to your deployment package instead of servers lib folder. Then the AS can take care of proper classloading during the (un-)deployment.

I have the same problem,
jboss 4.0.3SP1 with axis 1.3,
The other scenario (to copy the axis jars to the application) is not working because of another problem.
(my scenario is one ejb application and one web application, try to add axis to both ... and:
