[java ee programming] Fwd: Code

[jitesh dundas]

Hi Friends,

I need your help in this problem of URL Connection class.

I have to make a hit to the google spellcheck functionality(link mentioned
in the code), and get the resultset.

However, the code compiles fine but gives me run-time exeption: Connection
time out.

I just want to hit to an external website and get the result back. I am not
able to do the same for any website:-

Can you tell what is going wrong here:-

Code:-
----------

import java.net.*;
import java.io.*;
import java.util.*;

public class TestAuth
{
  public static void main (String args[])
  {

    String targetURL = "https://www.google.com/tbproxy/spell?lang=en";;
    try
    {

      System.setProperty("http.proxyHost", "*****.**.****.**.**");
      System.setProperty("http.proxyPort", "**");

      BufferedReader in = new BufferedReader(new
InputStreamReader(openURLForInput(new URL(targetURL),"*****","********")));
      String line;
      while ((line = in.readLine()) != null)
      {
          System.out.println(line);
      }
    }
    catch (IOException e)
    {
      e.printStackTrace();
    }
  }


  public static InputStream openURLForInput(URL url, String uname, String
pword) throws IOException
  {
    URLConnection conn = url.openConnection();
    conn.setDoInput (true);
    conn.setRequestProperty
("Authorization",userNamePasswordBase64(uname,pword));
    conn.connect ();
    return conn.getInputStream();
  }

  public static String userNamePasswordBase64
       (String username, String password)
  {
    return "Basic " + base64Encode (username + ":" + password);
  }

  private final static char base64Array [] =
  {
      'A', 'B', 'C', 'D', 'E', 'F', 'G', 'H',
      'I', 'J', 'K', 'L', 'M', 'N', 'O', 'P',
      'Q', 'R', 'S', 'T', 'U', 'V', 'W', 'X',
      'Y', 'Z', 'a', 'b', 'c', 'd', 'e', 'f',
      'g', 'h', 'i', 'j', 'k', 'l', 'm', 'n',
      'o', 'p', 'q', 'r', 's', 't', 'u', 'v',
      'w', 'x', 'y', 'z', '0', '1', '2', '3',
      '4', '5', '6', '7', '8', '9', '+', '/'
  };



  private static String base64Encode (String string)
  {
    String encodedString = "";
    byte bytes [] = string.getBytes ();
    int i = 0;
    int pad = 0;
    while (i < bytes.length) {
      byte b1 = bytes [i++];
      byte b2;
      byte b3;
      if (i >= bytes.length) {
         b2 = 0;
         b3 = 0;
         pad = 2;
         }
      else {
         b2 = bytes [i++];
         if (i >= bytes.length) {
            b3 = 0;
            pad = 1;
            }
         else
            b3 = bytes [i++];
         }
      byte c1 = (byte)(b1 >> 2);
      byte c2 = (byte)(((b1 & 0x3) << 4) | (b2 >> 4));
      byte c3 = (byte)(((b2 & 0xf) << 2) | (b3 >> 6));
      byte c4 = (byte)(b3 & 0x3f);
      encodedString += base64Array [c1];
      encodedString += base64Array [c2];
      switch (pad) {
       case 0:
         encodedString += base64Array [c3];
         encodedString += base64Array [c4];
         break;
       case 1:
         encodedString += base64Array [c3];
         encodedString += "=";
         break;
       case 2:
         encodedString += "==";
         break;
       }
      }
      return encodedString;
  }
}

Thanks in advance.
