It's not a stupid question. In fact, it's a frequently asked question, in
one form or another.

In the Web Services platform, a client never directly accesses the server.
All communications between them are in terms of XML, which is described by
an XML Schema (XSD), which is referred to by a WSDL that describes the
service. A proxy class mediates between the client program and all the XML
stuff that's going on in the middle, before the server is reached.

A proxy class is generated by some development tool that reads the WSDL and
associated schemas, and produces code in some programming language. The "Add
Web Reference" feature of Visual Studio is one such tool. WSDL.EXE, part of
the .NET SDK is another such tool. I believe that Java has tools like
"wsdl2j".

I hope that begins to answer your question. I should eventually put together
some reference materials to better answer these questions.

Welcome to the World of Web Services!

Hello Sajid,

Just to add to John's post I recommend to read this http://www.codeproject.com/dotnet/intro2websvc.asp

where is the presentation about how the proxy works
