My experiences with all Java (Axis2), .NET and Delphi webservices has been that pointing at the supplied url using Internet Explorer (not with other browsers) I’ve been able to view the available wsdl’s from the serviceinterfaces provided. Pasting the final url, indeed ending in ?wsdl, into the WebService discovery tool, either MyEclipse, Visual Studio, or SoapUI (and probably should work in Delphi as well), I successfully generated the required stubs for using/testing the service.
Hope This Helps,
