how to call a url from a java action in struts?

i am trying to send sms through a url as follows

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();
  }

but while running this one showing following exceptions

in thread "main" java.net.SocketException: Network is unreachable: connect

It is better you look at apache http client library and make a get request using it.
