How to display an application logo screen (a rectangular graphic) in Java? From what I know every Java application must start with a frame but I need to start it with some kind of container with no buttons or titlebars but with an image inside.

I found this at http://www.tactika.com/realhome/realhome.html

import java.awt.*;
 import java.awt.event.*;

 public class Splash extends Window {
   private Image splashImage;
   private int imgWidth, imgHeight;
   private String imgName;
   private static final int BORDERSIZE = 5;
   private static final Color BORDERCOLOR = Color.blue;
   Toolkit tk;
 
   public Splash(Frame f, String imgName) {
     super(f);
     this.imgName = imgName;
     tk = Toolkit.getDefaultToolkit();
     splashImage = loadSplashImage();
     showSplashScreen();
     f.addWindowListener(new WindowListener());
     }
   public Image loadSplashImage() {
     MediaTracker tracker = new MediaTracker(this);
     Image result;
     result = tk.getImage(imgName);
     tracker.addImage(result, 0);
     try {
       tracker.waitForAll();
       }
     catch (Exception e) {
       e.printStackTrace();
       }
     imgWidth = result.getWidth(this);
     imgHeight = result.getHeight(this);
     return (result);
     }

   public void showSplashScreen() {
     Dimension screenSize = tk.getScreenSize();
     setBackground(BORDERCOLOR);
     int w = imgWidth + (BORDERSIZE * 2);
     int h = imgHeight + (BORDERSIZE * 2);
     int x = (screenSize.width - w) /2;
     int y = (screenSize.height - h) /2;
     setBounds(x, y, w, h);
     setVisible(true);
     }

   public void paint(Graphics g) {
     g.drawImage(splashImage, BORDERSIZE, BORDERSIZE,
       imgWidth, imgHeight, this);
     }

   class WindowListener extends WindowAdapter {
     public void windowActivated(WindowEvent we) {
       setVisible(false);
       dispose();
       }
     }
   }


The following example use this image  (jht.gif) as the splash image.

 import java.awt.*;
 import java.awt.event.*;

 public class TestSplash {
   MyFrame theFrame;
   
   
   public static void main (String args[]){
     TestSplash t = new TestSplash();
     t.createMainFrame();
     }
     
   private void createMainFrame() {
     theFrame = new MyFrame("A Dummy Frame");  
     theFrame.setVisible(true);
     }

 }

 class MyFrame extends Frame {
   Splash mySplash;
   public MyFrame(String title){
     super(title);
     addWindowListener
       (new WindowAdapter() {
         public void windowClosing(WindowEvent e) {
           System.exit(0);
           }
         }
        );
     mySplash = new Splash(this, "jht.gif");
     
     // dummy delay so we can see the Splash!
     for(int i = 0; i < 3000; i++) {
       System.out.println(i) ;
       }
     setSize(200,200);
     }      
   }
