Daniel Taylor commented on JBAS-6268:
-------------------------------------
the server starts fine, but when I attempt to load the site and the default welcome page
is loaded the NPE is thrown.
Here is the full web.xml file, let me know if you need more information or if it can't
be reproduced.

while not crucial to the development of jboss, I speak from experience when I say that it
can take a long time to find the configuration error based upon the exception thrown...
