Java EE (Java Enterprise Edition) General Discussion

Hi,

I am using JAX WS to consume a .NET web service.
While trying to invoke the service, i get the following error :

javax.xml.ws.WebServiceException: org.apache.axis2.AxisFault: Transport error: 501 Error: Not Implemented

I suspect this to be an issue with the HTTP Protocol version. I know how to change the HTTP version in an Apache Axis generated stub. But how do i do in JAX WS?

Any help would be appreciated.

Thanks
