title: Appengine (Java) webservice needs refresh?
body: <p>I have created an Application using Appengine(Java) and GWT. Now I'm communicating to an android device with my Application using WebServices. But after some hours it failed to connect. Means my webservice stops working and to overcome this I had to refresh my application. </p>
  
  <p>How can I handle this situation? Are there any ways my webservice stay active 24*7 in AppEngine?</p>
  
  <p>My webservice body is :</p>
  
  <pre><code>    class webservice extends HttpServlet{
      @Override
      protected void doGet(HttpServletRequest req, HttpServletResponse resp)
              throws ServletException, IOException {
  
          doPost(req, resp);
      }
  
      @Override
      protected void doPost(HttpServletRequest req, HttpServletResponse resp)
              throws ServletException, IOException {
          // TODO Auto-generated method stub
           //What i want to do
         }
  }
  </code></pre>
