here's some simple code that might help you:

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

/*
<APPLET
        code=RolloverImage.class
        width=300
        height=300>
</applet>
*/

public class RolloverImage extends java.applet.Applet implements MouseListener, ImageObserver {
   

     private Image curImage;
     private Image image1;
     private Image image2;
     
     public void init()
     {
     
          setBackground(Color.green);
          addMouseListener(this);
         
          image1 = getImage(getCodeBase(), "pic1.jpg");
          image2 = getImage(getCodeBase(), "pic2.jpg");
         
          curImage = image1;
          setSize(300, 300);
     }

     public void paint(Graphics g) {
          g.setColor(Color.black);
          g.drawImage(curImage, 0, 0, 300, 300, this);
   }    

     public void mouseClicked(MouseEvent evt) {}
     
     public void mouseEntered(MouseEvent evt) {
          curImage = image2;    
          repaint();
     }
     public void mouseExited(MouseEvent e) {
          curImage = image1;    
          repaint();
     }
     
     public void mousePressed(MouseEvent e) {}
     public void mouseReleased(MouseEvent e) {}
           
}

If your using Swing then just use setRolloverIcon() method on your button to specify the rollover image.
