We fixed this. The web service and client are working now.
The .......Impl class on the client side is not needed, we found out.
Also, we had to make a few changes to some of the annotations in the
client generated code, I beleive the @WebMethod had a namespace and when
we removed it everything worked. If my memory serves me correctly and this
was
the actual change we made it looks like it might be related to what you saw
in the
SOAP messages.
Thanks for the help.

There's the problem. The WSDL says the "return" element should be
qualified. However, the response doesn't have it qualified. I'll be if
you
modify the WSDL to have elementFormDefault="unqualified" and regenerate the
client, it would work.

I've created my projects since my first post so come class and interface
names are different, but we are essentially talking about the some thing
here.
To respond to your comment, my client side code does have an
implementation
of the "port type" interface. See the code below (remember the name
changes):
I'm sure that the problem is on the client side since the Tomcat console
shows the
SOAP messages for the call to the server; the sayHello( ) called message
is
mine. See
the console message text below the source code.
I also just noticed a comment in the HelloWorldPortTypeImpl class. It
says
the
class is not complete. Can you provide some info on what I need to
complete it?
Thanks
