Varun,
The WS-Addressing and other WS-Security assertions require the service to a SOAP Published service. You can use any WSDL and just change a few options to make it a REST based service. On the WSDL tab make the SOAP Version Unspecified and check the bottom box.
On the HTTP tab, ensure that you pick the HTTP Methods you want to support:
Sincerely,
Stephen Hughes
