This is the first Web Service I am providing as an example that you can play with, test against, and copy.  It is about as simple as a Web Service can get, but I think that is a good place to start.  It is modeled after several other examples that implement a calculator.  The trick is that, like all the other endpoints I have implemented so far on this site, it is built almost completely with XSL.  For more information on how, check out the Kafka pages.

The format below is what I will use to describe the Web Services that will be available.  Add provides just a single method, Add, that adds two doubles and returns the sum.  Check out the service definition in WSDL, sample clients written with the Microsoft SOAP Toolkit and PocketSOAP, and the source code for the service itself.

 Function Add( A as Double, B as Double ) as Double
