在谷歌AWT的servlet讀取數據的發送由客戶端

Question

我想從桌面應用程序發送一些數據，以谷歌AWT小服務程序
我目前在我的系統（本地主機）嘗試這個，因爲我已經安裝了Eclipse插件
我發送數據這樣

URL url = new URL("http://localhost:8888/calendar"); 
URLConnection urlConnection = url.openConnection(); 
urlConnection.setDoOutput(true); 
PrintWriter out = new PrintWriter(urlConnection.getOutputStream()); 

String stringTosend = URLEncoder.encode(tf.getText(), "UTF-8"); 
out.write(stringTosend); 

和我的servlet是這樣

public class CalendarServlet extends HttpServlet { 
    public void doPost(HttpServletRequest req, HttpServletResponse resp) 
      throws IOException { 
     resp.setContentType("text/plain"); 
     String input = req.getReader().readLine(); 
     resp.getWriter().println(input); 
    } 
} 

但是我又回到爲NULL。
