[Shivantha Huruggamuwa]

Hi all,
I am using Axis 1.5 to create a client to Microsoft .net  web services ,it
has a notification operation.
Here is the simple WSDL I am using to try to codegen.


<wsdl:definitions xmlns:axis2="http://quickstart.samples/"; xmlns:soap12="

            </wsdl:output>
        </wsdl:operation>
