I can defined method with @Produces annotations, but how can I get
differenent result, eg, json and xml.

        @GET
        @Path("/registerUser")
        @Produces({ MediaType.APPLICATION_JSON,
MediaType.APPLICATION_XML })
        public String registerUser(@QueryParam("deviceId") String
deviceId){...}
