Have you tried writing a simple java class to run just to make sure
headless works outside of pljava?
This class will do the check:
import javax.swing.*;
public class HTest {
public static void main(String[] args) {
JButton b = new JButton("Testing Headless");
}
}
If headless is not working, you'll get an exception. I actually found
that on my CentOS linux box, java.awt.headless was by default set to
true, and therefore I only got the link exception when running with
-Djava.awt.headless=false.
