my servlet do post method which I am invoking looks like this

    protected void doPost(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {
        int incrementAndGet = counter.incrementAndGet();
        int count = counter.get();
        CometEngine engine = CometEngine.getEngine();
        CometContext<?> context = engine.getCometContext(contextPath);
        context.notify(null);
        response.setContentType("application/json; charset=UTF-8");
        JSONObject json = new JSONObject();
        json.put("count", count);
        PrintWriter writer = response.getWriter();
        writer.print(json);     
//        request.getRequestDispatcher("index.jsp").forward(request, response);
        return;
    }

why am i getting this error while i have all the imports correct and added the json-rpc-1.0.jar into the project?
