SocketException in WSAD

[Shannon Sims]

Hello,
I'm trying to run this simple code in WSAD 5.1.2, but keeps giving me a Socket Exception:

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;
 
public class TestURL
{
   public static void main(String[] args) throws Exception 
   {
URL yahoo = new URL("http://www.yahoo.com/");
HttpURLConnection httpConnection = (HttpURLConnection)
                                                yahoo.openConnection();

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

String inputLine;

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

in.close();
   }
}
 
Exception in thread "main" java.net.SocketException: Operation timed out: connect:could be due to invalid address

Internet proxy is enabled, host and port is set. Is there something else that would cause this error?

Thanks in advance for your help!
