      @Context HttpServletRequest req,
      @Context HttpServletResponse res); @GET @Path("/{entityType}") @Produces({ MediaType.APPLICATION_JSON /* , MediaType.APPLICATION_XML */}) TimelineEntities getEntities(
      @Context HttpServletRequest req,
      @Context HttpServletResponse res,
      @PathParam("entityType") String entityType,
      @QueryParam("primaryFilter") String primaryFilter,
      @QueryParam("secondaryFilter") String secondaryFilter,
      @QueryParam("windowStart") String windowStart,
      @QueryParam("windowEnd") String windowEnd,
      @QueryParam("fromId") String fromId,
      @QueryParam("fromTs") String fromTs,
      @QueryParam("limit") String limit,

      @Context HttpServletRequest req,
      @Context HttpServletResponse res,
      TimelineEntities entities);  }### Answer:
@Test public void testAbout() throws Exception { WebResource r = resource(); ClientResponse response = r.path("ws").path("v1").path("timeline") .accept(MediaType.APPLICATION_JSON) .get(ClientResponse.class); assertEquals(MediaType.APPLICATION_JSON_TYPE, response.getType()); TimelineWebServices.AboutInfo about = response.getEntity(TimelineWebServices.AboutInfo.class); Assert.assertNotNull(about); Assert.assertEquals("Timeline API", about.getAbout()); }
