Hiding the Frame Border

Question

Hi group,
You know when you start up Mozilla you get a little picture which flashes up breathing fire? I wanna make a frame do that! I've got it so it flashes up a picture for 3 seconds and disposes of itself. From the main application it is run as a thread. I run it by calling
new showflash().
Here is the code ...
import java.awt.*;
import javax.swing.*;
import java.awt.geom.*;
public class Flashpan extends JPanel {
private ImageIcon m_icon;
public Flashpan () {
JFrame frame = new JFrame("Border Title Bar");
frame.setSize(669, 525);
Container content = frame.getContentPane();
content.add(this);
m_icon = new ImageIcon("image.jpg");
/*flash the window*/
frame.setVisible(true);
/* 3 second delay */
try {
Thread.sleep(3000);
} catch (InterruptedException e) {
/*kill the window*/
frame.setVisible(false);
frame.dispose();
public void paintComponent(Graphics g) {
super.paintComponent(g);
Graphics2D g2d = (Graphics2D) g;
m_icon.paintIcon(this, g2d, 10, 10);
public static void showflash() {
new Flashpan();
Now the question is How do I make the window borders disappear. I have only one object contained in the frame, the picture. I want everything to disappear without killing it except this picture object? How do I do it? Im sure many people must have done this!! Maybe my code sucks.. pls forgive me :P
Ive been looking at Inset() BorderLayout() etc.. etc.. but cant seem to work it out or find an example. I thought maybe it was frame.Inset(0,0,0,0) but I was wrong.

Bingo, Ta for that....
Complete code is as follows (screen centers now)
import java.awt.*;
import javax.swing.*;
import java.awt.geom.*;
public class Flashpan extends JPanel {
private ImageIcon m_icon;
public Flashpan () {
JWindow frame = new JWindow();
frame.setSize(640, 480);
/* Get the size of the screen */
Dimension dim = Toolkit.getDefaultToolkit().getScreenSize();
/* Determine the new location of the window */
int w = frame.getSize().width;
int h = frame.getSize().height;
int x = (dim.width - w) / 2;
int y = (dim.height - h) / 2;
/* Move the window */
frame.setLocation(x, y);
Container content = frame.getContentPane();
content.add(this);
m_icon = new ImageIcon("image.jpg");
/*flash the window*/
frame.setVisible(true);
/* 3 second delay */
try {
Thread.sleep(3000);
} catch (InterruptedException e) {
/*kill the window*/
frame.setVisible(false);
frame.dispose();
public void paintComponent(Graphics g) {
super.paintComponent(g);
Graphics2D g2d = (Graphics2D) g;
m_icon.paintIcon(this, g2d, 0, 0);
public static void showflash() {
new Flashpan();
