DukesAgeResource is a JAX-RS resource class that responds to HTTP GET requests and returns a String representing the age of Duke at the time of the request.
To create DukesAgeResource, use the wizard provided by the JAX-RS plug-in for NetBeans 6.7 IDE to generate the resource class. This class is annotated with the javax.ws.rs.Path annotation, which specifies the URL suffix to which the resource will respond. DukesAgeResource has a single method, getText, annotated with the javax.ws.rs.GET and javax.ws.rs.Produces annotations. @GET marks the method as a responder to HTTP GET requests, and @Produces specifies the MIME-type of the response sent back from getText to clients. In this case, the MIME-type is text/plain.
