It's not urban legend, you missed an important detail..NET can handle arrays of complex types, but you run into interoperability problems when the complex types consist of things other than XSD primitives. Don't take my word for it, here's Microsoft's tech note on the subject:
http://support.microsoft.com/default.aspx?scid=kb;en-us;326791 Maybe WSE has fixed some of this, but you don't always have the luxury of talking to someone who runs the latest software in the real world. This is why I said you need to keep WSDL's simple to maximize interoperability, if you have the ability to do so. Go to a Microsoft seminar on J2EE/.NET compatibility and they'll tell you the exact same thing. -- Andy >>> [EMAIL PROTECTED] 12/16/04 11:51AM >>> I don't know where the urban ledgend that .NET can't handle arrays of complex types that contain complex types comes from, but its not true. I have a service that returns arrays of complex types containing arrays of complex types and it works fine with a .NET client.
