URL Parts in REST Service

http://localhost:8080/restful/resources/helloworld... it’s good to take a look how the URL is composed because when we start creating the service, you will see how the various parts of the URL—namely, the context root restful, the mapping of the RESTful resource container resources, and the name of the service itself—all manifest themselves in either the code or the XML configuration files.
