HttpURLConnection problem?????

[Hemant KS Sengar]

Hi All!!
I was trying to get response code and response message from the server by writing this very small code... but I dont know where I'm making mistake because it is giving UnknownHostException.
Though for all other methods it is working fine except
getResponseCode() and getResponseMessage() methods.
Code goes here:
-------------------
import java.net.*;
import java.io.*;
import javax.swing.*;
import java.awt.*;
public class SourceViewer {
public static void main(String[] args){

try{
URL u = new URL("http://www.amnesty.org/");
HttpURLConnection uc = (HttpURLConnection) u.openConnection();
int code = uc.getResponseCode();
System.out.println("HTTP 1.x"+code);
}
catch(IOException e){
e.printStackTrace();
System.err.println(e);
}
}
}
-------------
Thanks in advance.........

Worked fine for me. I got this:
HTTP 1.x 200
If you are getting an UnknownHostException, it seems like it is a DNS problem.

Hi Matt!
Thanks for your prompt reply. Actually I access Internet through Dial-up connection to my college server ...is this the reason(DHCP). Is there any way to get it solved....
Thanks

Hi Hemant..
Try these things...
1. try giving the IP address instead of the url...
2. check whether u r behind a proxy server..if u r then change the system property of Httpproxyhost and Httpproxyport (am not sure of the exact spelling) to ur proxy server's ip and port and then run the code.
