I have this java program that does NS lookups

import java.net.*;

public class nlookup {
    public static void main(String args[]) {
        try {
            System.out.println(InetAddress.getByName(args[0]));
        }
        catch(Exception e) {
            e.printStackTrace();
        }
    }
}

Now, if I take the linux j2sdk (I'm using 1.4.0) and compile and run it on
my linux box, I get output like this:

[mrami@s199 mrami]$ java nlookup ftp.freebsd.org
ftp.freebsd.org/62.243.72.50
[mrami@s199 mrami]$

On my FreeBSD system (FreeBSD 4.5-RC1), when I do the same thing,

mrami@gateway:~/src/test$ java -cp . nlookup ftp.freebsd.org
java.net.UnknownHostException: ftp.freebsd.org
        at java.net.InetAddress.getAllByName0(InetAddress.java:920)
        at java.net.InetAddress.getAllByName0(InetAddress.java:890)
        at java.net.InetAddress.getAllByName(InetAddress.java:884)
        at java.net.InetAddress.getByName(InetAddress.java:814)
        at nlookup.main(nlookup.java:6)
mrami@gateway:~/src/test$

(Yes, same nameserver)

Is this nature's way of telling me I need to use the native SDK? Or am I
doing something stupid?

Marc.
