Network Access inside Chroot environment

Hey, We are trying to integrate selenium with domjudge. Could you please help in figuring out the ways we can provide network access in chroot environment. We are trying to run the code below via domjudge. And domjudge is returning the following exception: java.net.UnknownHostException: www.google.com. Could you let us known if there is a work around.

code:

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

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

URL str = new URL("http://www.google.com/"); BufferedReader in = new BufferedReader( new InputStreamReader(str.openStream()));

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