If you check out the serialize-dom-scheme branch, you get a really nice WSDL code generator for Python (much, much better than SOAPpy or normal ZSI). Then, go get pyGridWare. It adds a Twisted service container that can house ZSI-based web services.

WSDL code generation completely defies the purpose of having WSDL in the first place, refer: http://webservices.xml.com/pub/a/ws/2003/07/22/wsdlfirst.html http://webservices.xml.com/pub/a/ws/2003/07/22/wsdlfirst.html

You misunderstood me. Perhaps if I call it a "python code generator from WSDL descriptions", you would have understood more clearly. Even though I fall into the camp of "write your wsdl, generate language specific bindings, implement service and client using specific langauges", I am not vehemently opposed to features like those in WSRF.NET. In that toolkit, users use C#-specific language features to mark up their C#-written classes. Those markups are used to guide the generation of WSDL. From what we can tell (as implementers of Python-based grid services that have been tested to interoperate with C# WSRF grid services) there are no problems with this approach. In fact, the process is so natural we have considered using decorators in Python to do the same thing. This sort of feature really only exists to provide developers who prefer to work in a native language rather than specifying the messages they want to exchange. I read the article you cited. It is only an opinion piece, and provides no coherent, logical argument for their viewpoint. Further, the article is obviously dated due to its focus on RPC encoding, which is not a viable approach for writing web services these days. Dave
