Issues with java.net.Proxy class

**312c** · 07-02-2009, 07:50 PM

When I run the following code I expect it to display:

194.36.10.154
aaa.bbb.ccc.ddd

where aaa.bbb.ccc.ddd is my real IP. This does not happen, it instead displays:

194.36.10.154
194.36.10.154

when I uncomment the pause, the code performs as expected. Is there something going on behind the scenes causing this or is it a bug in java?

Code:

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.InetSocketAddress;
import java.net.Proxy;
import java.net.SocketAddress;
import java.net.URL;
import java.net.URLConnection;

public class ProxyTest {
	public static void test1() {
		String socks_server_proxy = "194.36.10.154";
		int socks_port = 3128;
		try {
			SocketAddress addr = new InetSocketAddress(socks_server_proxy,
					socks_port);
			Proxy proxy = new Proxy(Proxy.Type.HTTP, addr);

			URL url = new URL("http://312c.info/ip.php");
			URLConnection conn = url.openConnection(proxy);

			BufferedReader in = new BufferedReader(new InputStreamReader(conn
					.getInputStream()));
			String line;
			while ((line = in.readLine()) != null) {
				System.out.println(line);
			}
			in.close();
		} catch (Exception e) {
			e.printStackTrace();
		}
	}

	public static void test2() {
		try {
			URL url2 = new URL("http://312c.info/ip.php");
			URLConnection conn2 = url2.openConnection(Proxy.NO_PROXY);

			BufferedReader in2 = new BufferedReader(new InputStreamReader(conn2
					.getInputStream()));
			String line2;
			while ((line2 = in2.readLine()) != null) {
				System.out.println(line2);
			}
			in2.close();
		} catch (Exception e) {
			e.printStackTrace();
		}	

	public static void p(Object[] s) {
		for (int i = 0; i < s.length; i++)
			if (s[i] != null)
				System.out.println(s[i].toString());
			else
				System.out.println("null");
	}

	public static void main(String[] args)
	{
		test1();
//		try {
//			Thread.sleep(5000);
//		} catch (InterruptedException e) {
//			e.printStackTrace();
//		}
		test2();
	}
