SOAP Server with WSDL?

Java and .NET based tools can auto-generate WSDL from code. Python does
not have such because function definitions do not contain the type
information required for such a tool. However , you can grab a free
Java (Netbeans with Enterprise pack) or .NET (Visual Studio Express)
IDE (or just the respective SDK if you don't mind reading through the
docs), create a stub function, mark it as a WebMethod, let it generate
the WSDL and pass it to wsdl2py that comes with ZSI. This is a twisted
approach.

But you state that you don't need to publish an interface. If that is
the case, it can be as simple as this.

      import SOAPpy
      def hello():
	  return "Hello World"

      server = SOAP.SOAPServer(("localhost", 8080))
      server.registerFunction(hello)
      server.serve_forever()

I posted a few days ago a simple guide to choosing a remoting
framework.

For *complex* objects, you need a stateful remoting mechanism. The
choice is Pyro if both the server and all the clients are written in
Python. Else, use CORBA or ICE with DMI. All of these are simple to use
for simple remote object invocations although distributed computing in
general does have a learning curve.
