    StringBuffer result = new StringBuffer(); 
    String line = ""; 
    while ((line = rd.readLine()) != null) { 

     result.append(line); 
    } 
     // i tried to use this to view this so that it can appear in the browser 
     PrintWriter printwriter=response.getAllHeaders(); 
     printwriter.print(result.toString()); 

    System.out.println(result.toString()); 
      System.out.println("Done!");

您可以使用Fiddler做到這一點（谷歌搜索提琴手並在計算機上安裝）。它會顯示你所有的http請求和響應。不需要修改代碼。 –

System.out.println方法是打印到控制檯，所以你需要使用HttpServletResponse打印你的文本到瀏覽器

public void doPost(HttpServletRequest request, HttpServletResponse response) { 
// your code here 
response.setContentType("text/html"); 
response.getWriter().print(result); 
}
