Hi,

As per the document.

Root resource classes are POJOs (Plain Old Java Objects) that are either annotated with@Path or have at least one method annotated with @Path or a request method designator such as @GET, @PUT, @POST, or @DELETE. Resource methods are methods of a resource class annotated with a request method designator. This section describes how to use Jersey to annotate Java objects to create RESTful web services.
