and what is the type for the @Produces annotation ? (if required at all)

        @GET
        @Produces( { MediaType.TEXT_HTML, MediaType.TEXT_PLAIN })
        @Path("{competition}/graph")
        public Response graph(@PathParam("competition") String login) {
                return Response
                                .noContent()
                                .header(
                                                "Location",
                                                "http://chart.apis.google.com/chart?cht=p3&chd=t:60,40&chs=250x100&chl=Hello|World")
                                .build();
        }
