java - 如何从struts中的java Action 调用url？

Question

我正在尝试通过如下网址发送短信

public  void sendsms() throws IOException 
    {
  URL sms = new URL("http://india.timessms.com/http-       api/receiverall.asp?username=way2sijo&password=*******i&sender=Demo&cdmasender=9930065297&to=919930065297&message=Hello");
  BufferedReader in = new BufferedReader(
     new InputStreamReader(sms.openStream()));

  String inputLine;

  while ((inputLine = in.readLine()) != null)
      System.out.println(inputLine);

  in.close();
  }

但是在运行这个程序时显示以下异常

in thread "main" java.net.SocketException: Network is unreachable: connect
        at java.net.PlainSocketImpl.socketConnect(Native Method)
        at java.net.PlainSocketImpl.doConnect(Unknown Source)

        at sun.net.www.protocol.http.HttpURLConnection.getInputStream(Unknown Source)
        at java.net.URL.openStream(Unknown Source)

我该如何解决这个问题......提前致谢......

最好查看 apache http 客户端库并使用它发出 get 请求。
