As i already said before, i'm not a soap expert, not at all. Nevertheless, i think generating wsdl files from existing java code is an easy way : wsdl syntax is not so friendly. I known such a comparison is not always welcome : with CORBA we all first write the services interface, using IDL, before code generation. But, from my point of view, IDL is quite more easy to write than wsdl ! I agree with you about interoperability. In this domain, i'd like to have actual feedback from real projects. I really think all these web services miracle appear a bit confusing, just as wsdl syntax ! Your suggestion about alternative methods and tools to mkae wsdl first are welcome... Regards.
