If you write a Servlet as shown below that could work fine for both POST as well as GET Http Requests.

public class CommonServlet extends HttpServlet {
        protected void doGet(HttpServletRequest req, HttpServletResponse resp)
                        throws ServletException, IOException {
                doProcess(req, resp);
        }

        protected void doPost(HttpServletRequest req, HttpServletResponse resp)
                        throws ServletException, IOException {
                doProcess(req, resp);
        }

        private void doProcess(HttpServletRequest req, HttpServletResponse resp) {
        //write your code
        }
}
