Image on Button..

Try something like this:
URL url = getClass().getResource(iconPath);
ImageIcon image = new ImageIcon(url);
JButton button= new JButton(image);

EK

In java 1.1.x, you can create a class which extends the Button's class and use the method paint() in it to display your image's file.
Here is an example :

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

public class BoutonImage extends Button implements ActionListener
{
Image i;

public BoutonImage()
{
i = Toolkit.getDefaultToolkit().getImage("Hlpcd.gif");
this.addActionListener(this);
this.validate();
}

public void paint(Graphics g)
{
g.drawImage(i, 5, 5, this.getSize().width+5, this.getSize().height+5, this);
this.setSize(60, 30);
}


public void actionPerformed(ActionEvent e)
{
System.exit(0);
}
}

This code is not perfect because you need to refresh manually the frame to see the button behind the image, but it works !!

So long,
