Generate a Java REST Client from a WADL

The Web Application Description Language (WADL) is an XML-based file format that describes your RESTful Web services application. By default, a basic WADL is generated at runtime and can be accessed from your RESTful Web service by issuing a GET on the /application.wadl resource at the base URI of your REST application. For example: GET http://<path_to_REST_app>/application.wadl.

You can also use the options method to return the WADL for particular resource, as shown in Example: WADL Describing a REST Web Service.
