As communications protocols and message formats are standardized, it becomes increasingly important to describe these communications in some structured way. The Web Services Description Language (WSDL) addresses this need by defining an XML grammar for describing Web services as collections of communication endpoints capable of exchanging messages. WSDL service definitions provide documentation for distributed systems and for automating the details involved in communication between applications.
When you define a Web service in EAServer, the WSDL file can be automatically generated from the information you provide.
The WSDL document describes a component that you want to make available as a Web service, as well as its location. You can also publish the location of a WSDL document to a UDDI registry on the Web.
The Web services GUI allows you to select a UDDI public host site and login. After you log in, you can add business and service data to the UDDI registry. Once you have published information to the registry, each time you log in, the information is retrieved and available for you to review, modify, or delete.
A business partner can invoke a Web service without knowing how to write SOAP messages by using Web services generated client-side files and artifacts (the collection of files on the client-side that handles communication between a client and a Web service. They include the stub class, service definition interface and additional classes), and the WSDL document that describes your Web service.
See the WSDL information pages for more information.
