Simulate multiple trees on a JTree

Question

Hi all,
is there a way to remove the line that binds the nodes of a tree?
I want to have something like msn friend's list, where there is a tree with multiple nodes "root nodes", and they have 0 or more children and no node is connected to any other by a line.
thanks in advance

Here's a util to display those look and feel defaults:
import java.awt.*;
import java.util.*;
import javax.swing.*;
public class UIManagerExample {
    public static void main(String[] args) {
        java.util.List < String > keys = new ArrayList < String > ();
        UIDefaults defs = UIManager.getLookAndFeelDefaults();
        for (Object key : defs.keySet()) {
            String keyString = key.toString();
            if (keyString.startsWith("Tree."))
                keys.add(keyString);
        Collections.sort(keys);
        for(String key : keys) {
            Object value = defs.get(key);
            System.out.format("%-32s:%s%n", key, value.toString());
}
