Tony,
I don't see anything wrong with your sample other than the fact that your
XML output doesn't
have a new line after the xml header: <?xml version="1.0">
My only suggestion at this point it to debug the WSPG and find out what URL
it is trying to access.
It should exlpain why your servlet is never reached.
Your pipeline seems good.
It must be a very simple misconfiguration problem, because your example is
pretty simple and
the WSPG demo works against much more complicated sites.
I am sorry I cannot offer a better solution.
Please let me know what you find,
Ivelin
