Hi!
I post code of a splash screen I'm using. I expect it helps you:
import java.awt.*;
public class SplashWindow extends Window implements Runnable {
     private Thread runner;   
     private Image splashIm;   
     private StringBuffer Message;   
     private Image Buffer;   
     private Graphics gBuffer;   
     private int animationStep;
     private int width;
     private int height;
     public SplashWindow(Frame parent, Image splashIm) {       
          this(parent, 400, 222, splashIm);
     public SplashWindow(Frame parent, int width, int height, Image splashIm) {       
          super(parent);
          this.width = width;
          this.height = height;
          this.splashIm = splashIm;       
          setSize(width,height);
          animationStep = 0;       
          /* Center the window */       
          Dimension screenDim = Toolkit.getDefaultToolkit().getScreenSize();       
          Rectangle winDim = getBounds();       
          setLocation((screenDim.width - winDim.width) / 2, (screenDim.height - winDim.height) / 2);
          setVisible(true);       
          toFront();       
          start();   
     //Used for flicker-free offscreen drawing   
     public void addNotify() {       
          super.addNotify();       
          Buffer = createImage(width, height);
          gBuffer = Buffer.getGraphics();   
     public void buildBuffer() {     
          if (splashIm != null) {       
               gBuffer.setColor(Color.white);       
               gBuffer.fillRect(0, 0, width, height);
               gBuffer.drawImage(splashIm,0,0,this);       
               drawAnimation();               
               //Overlay a cute animation       
               gBuffer.setColor(Color.white);       
               gBuffer.drawString(Message.toString(), (width/20), (height-8));
     public void drawAnimation() {     
          if (gBuffer == null)       
               return;     
          if (animationStep < 0)       
               animationStep = 399;     
          for (int i=0; i<400; i++) {       
               int thisColor = (int)(((float)(animationStep + i))/(float)400 * (float)256);       
               while (thisColor > 255) {         
                    thisColor = thisColor-256;       
               while (thisColor < 0) {         
                    thisColor = thisColor+256;       
               gBuffer.setColor(new Color(0, 0, thisColor) );
               gBuffer.drawLine(i, (width/2), i, height);
     public void paint(Graphics g) {     
          if (Buffer != null)       
               if (g != null)         
                    g.drawImage(Buffer, 0, 0, this);   
     // Use this to change the status message. Note that the redraw   
     // is done elsewhere (FYI, inside the animation thread below)   
     public void setMessage(String message) {     
          Message = new StringBuffer(message);   
     public void start() {
          runner = new Thread(this);     
          runner.start();   
     public void stop() {
          runner.interrupt();     
          runner = null;   
     public void run() {
          try { 
               while (!Thread.interrupted()) {           
                    buildBuffer();                 
                    //Build the offscreen buffer           
                    this.paint(this.getGraphics());
                    //Draw the offscreen buffer           
                    animationStep-=8;           
                    Thread.sleep(40);        
          catch(InterruptedException e) {}   
     protected void finalize() {     
          stop();     
          this.splashIm.flush();     
          this.splashIm = null;     
          Buffer.flush();     
          Buffer = null;   
}I use this splashscreen through this class:
import java.awt.*;
public class SplashScreen extends javax.swing.JFrame {
     private SplashWindow sw = null;
     public SplashScreen(String titulo, String imagen, int w, int h) {
          super(titulo);
          setSize(w,h);
          Dimension screenDim = Toolkit.getDefaultToolkit().getScreenSize();
          Rectangle frameDim = this.getBounds();
          setLocation((screenDim.width-frameDim.width)/2,(screenDim.height-frameDim.height)/2);
          MediaTracker mt = new MediaTracker(this);
          Image splashIm = Toolkit.getDefaultToolkit().getImage(this.getClass().getResource(imagen));
          mt.addImage(splashIm,0);          
          try { 
               mt.waitForID(0);
          catch(InterruptedException ie) {}
          sw = new SplashWindow(this, w, h, splashIm);
     public void setMensaje(String mensaje) {
          if (sw != null)
               sw.setMessage(mensaje);
     public void cerrar() {
          sw.dispose();
          this.setVisible(false);
          this.dispose();
}Maybe some code are in spanish, but you can easily translate to english.
Regards.
