WLS adding m: namespace to webservice response

Question

I have created the most simple webservice possible to recreate the problem, the HelloWorld webservice. It takes a name parameter as string to the getGreeting operation and returns a string response. As you will see in the examples enclosed below, the response has a namespace generated as xmlns:m="http://www.mywebsite.com". The true namespace, as defined in the WSDL (also enclosed below), is xmlns:hwns="http://www.mywebsite.com".
This is really a problem for me in working with responses in Aqualogic and XPath to parse the response. I expect a namespace of 'hwns' and instead get the mystery namespace of 'm' which I cannot depend upon appearing consistently. All help in resolving this would be greatly appreciated.

Answer 1

The only way I found for doing this was create a transformation on the final response in the very beginning of my bpel process and add the xsi namespace explcitily.
