The @Parent annotation provides the ability to define a base template URI for the URI specified in a resources @Path annotation.
If a resource is annotated with the @Parent annotation, the Apache Wink runtime calculates the final resource template by first retrieving the value of the @Parent annotation, which holds the parent resource class, and then concatenates the resource path template definition to the path template definition of the parent resource.

Explanation
In the example, the user defined two resources: A ParentResource and ResourceA. ParentResource defines the @Path annotation to associate it with "services" URI. ResourceA defines the @Path annotation to associate it with "service1" URI and defines ParentResource to be its parent by specifying it in the @Parent annotation. In this case, the final URI path for ResourceA is "services/service1".
