Looking for good WSDL manual - plain C++ oriented

[mom_newbie]

Dear all,

Could someone suggest a good WSDL reading, oriented for manual Web services
implementation?

There are plenty working ATL and .NET examples in Internet, but I have
troubles making a plain C++ ISAPI Web service.

I took the WSDL from:

http://msdn.microsoft.com/archive/de...lexplained.asp

and created both client and server as .NET without a problem.

Then I replaced the Web service with my own, dumb C++ ISAPI extension,
which returns exactly the same data, and the .NET client failed with unknown
error.

My goal is to convert an existing Web application to a Web service - in
order to give a chance to everybody to write a frontend, by their favourite
means, or at least using .NET.

This Web app *cannot* be rewritten using .NET or ATL.

Thanks!

P.S. Here is the WSDL I tried and the server response I emulated:
