Hi!
It is possible to obtain the HttpServletRequest object of a web service request in a JAX-WS web service handler.
Using the getRequestURL method
you should be able to retrieve the URL the client used to perform the request.
In the handler, you can then insert the data you need in the web service into the
SOAP message context.
The message context can later be obtained in the web service, via the WebServiceContext.
Best wishes!
