WebLogic Workshop provides a way to get a WSDL from a public or private UDDI registry and bring it in as a Web Service control in your JWS file.
To Take a WSDL from a UDDI Registry and Add it as a Control
A JCX file is created in the same directory as the web service to which it was being added, and a reference to that control will be added to your web service. This control can now be used to access the web service represented by the WSDL.
