When I use "<wsdl art name="testPart" element="tns:ConcatS"></wsdl art>" It works fine. But based upon my study from an article : If RPC Style messaging is used then part element must have "type" attribute instead of element.
With the following I can not generate the Java code. "<wsdl art name="testPart" type="tns:ConcatS"></wsdl art>"
I’ve looked at a lot of different solutions, and in my humble opinion Aspose is the way to go. Here’s the link: http://aspose.com
