I have a project where I have created web service proxy classes with wsdl.exe and then simply create an instance of that class (inherits System.Web.Services.Protocols.SoapHt
Its a free for personal use Java app. Among other things you can
set it up to run as a dummy test server. Just load up hte WSDL
and enter the dummy data.
In test server mode it will log your requests so you can see whats happening
inside the request message.
