Let me clarify further,
When you’re developing Web services, ordinarily you can either start with a WSDL file and generate your service from it (called Top Down) or start with the POJOs that make up your Web service and get a WSDL based on the POJO for your potential clients to use (called Bottom Up).
Your question applies to the Bottom Up scenario. Once you actually generate the service using our wizards and then deploy it, you can get the WSDL for your service by navigating to this page: http://<server>:<port>/ServiceApp/services – here you’ll see a list of Services in your application and a link to a WSDL resource which you can distribute.
Hope this helps.
