[java ee programming] Help in URL Connectin Class

[jitesh dundas]

Hi Friends,

I could use your help now:-

I have to hit this Google URL and get the resultset. The result is string
type.

URL -> "
http://www.google.com/transliterate/indic?tlqt=1&langpair=en|hi&text=amitabachan,blog&&tl_app=1
"
When you put this into the URL and press enter, it will give you the
modified string with the result(array).


I am tring to do the same thing using Java program, but it is printing the
entire HTML page of transliterate.

The code is as follows:-
-----------------------------------
import java.io.*;
import java.net.*;
import java.util.*;

public class URLExample
{
    public static void main(String[] args) throws Exception
    {

      try
      {
     Properties systemSettings = System.getProperties();
         systemSettings.put("http.proxyHost", "proxy.it.iitb.ac.in");
         systemSettings.put("http.proxyPort", "80");
     systemSettings.put("sun.net.client.defaultConnectTimeout", "10000");
     systemSettings.put("sun.net.client.defaultReadTimeout", "10000");

      System.out.println("Properties Set");
     Authenticator.setDefault(new Authenticator()
         {
                                protected PasswordAuthentication
getPasswordAuthentication()
                                {
                                        return new
PasswordAuthentication("aaqua", "aaqua123".toCharArray()); // specify ur
user name password of iitb login
                                }
                        });
    System.setProperties(systemSettings);
    System.out.println("After Authentication & Properties Settings");


    //the input to google api
    String str = "
http://www.google.com/transliterate/indic?tlqt=1&langpair=en|hi&text=amitabachan,blog&&tl_app=1
";
    String stringToReverse = URLEncoder.encode(str, "UTF-8");

    URL url = new URL(str);
    URLConnection connection = url.openConnection();
    connection.setDoOutput(true);

    OutputStreamWriter out = new OutputStreamWriter(
connection.getOutputStream());
    out.write("string url=" + str);
    out.close();

    BufferedReader in = new BufferedReader( new InputStreamReader(
connection.getInputStream()));

    String decodedString;

    while ((decodedString = in.readLine()) != null) {
        System.out.println(decodedString);
    }
    in.close();
      }
      catch(Exception ex)
      {
      System.out.println("Exception->"+ex);
      ex.printStackTrace();
      }

    }
}
----------------------------------


I modified the same page as a JSP page and it opens up the transliterate
page of Google. I need the result from the string entered, not the page.

     systemSettings.put("sun.net.client.defaultConnectTimeout", "10000");
     systemSettings.put("sun.net.client.defaultReadTimeout", "10000");

      out.println("Properties Set");
     Authenticator.setDefault(new Authenticator()
         {

                                {
                                        return new
PasswordAuthentication("aaqua", "aaqua123".toCharArray()); // specify ur
user name password of iitb login
                                }
         });
    System.setProperties(systemSettings);
    out.println("After Authentication & Properties Settings");


    //the input to google api

    OutputStreamWriter outwr = new OutputStreamWriter(

    String decodedString;

    while ((decodedString = in.readLine()) != null)
    {
        out.println(decodedString);
    }
    in.close();

}
catch(Exception ex)
{
  out.println("Exception->"+ex);
  PrintWriter pw = response.getWriter();
  ex.printStackTrace(pw);
}
