java problem

Draupnir

Im trying to write a simple program to connect to a website using URL objects. However, im constantly getting this UnknownHostException. Anything Ive read regarding this so far seems to talk about proxys, but I dont use one!

Anyone know whats going on?

Heres my simple code:

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

class Tester
{
public static void main(String[] args)
{
try {
URL yahoo = new URL("http://www.yahoo.com");
URLConnection yc = yahoo.openConnection();

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


}catch (UnknownHostException e) { e.printStackTrace(); // new URL() failed

} catch (MalformedURLException e) { e.printStackTrace(); // new URL() failed

} catch (IOException e) { e.printStackTrace(); // openConnection() failed

}
System.out.println("Done");
}
}

I THINK you need "http://&quot; in front of it.

might be the problem described here
under the heading "A More Serious Issue"

Draupnir

yeah I was connected to the Internet and I also had http in front of it thanks Dan! Got the program running by using my laptop. I only get that eror on my desktop for whatever strange reason, even though im connecting both to the same router.
