Locate the WSDL file that defines the Web service that you want to implement. You can develop a WSDL file or obtain one from an existing Web service through e-mail, downloading or a Uniform Resource Locator (URL).
To develop Web services based on the JAX-WS programming model, you can use a bottom-up development approach starting from existing JavaBeans™ or enterprise beans or you can use a top-down development approach starting with an existing Web Services Description Language (WSDL) file. This task describes the steps when using the top-down development approach.
