Saving a JPanel as an image

Question

Hi peeps,
I've written the following code after reading many threads about how to save a JPanel as an image. On the whole, it works. But the JPanel itself contains many different bits such as Line2D objects and other shapes, as well as ImageIcons. So when the JPanel is saved, the shape objects save ok but the icons do not get saved. Does anyone know a better solution please?
By the way: "area" is the var name for a JPanel and "toSave" is a File object in the code below...
BufferedImage image = new BufferedImage(maxHorizontal, maxVertical, BufferedImage.TYPE_INT_RGB);
Graphics2D g = image.createGraphics();
g.setRenderingHint(RenderingHints.KEY_FRACTIONALMETRICS,RenderingHints.VALUE_FRACTIONALMETRICS_ON);
g.setRenderingHint(RenderingHints.KEY_TEXT_ANTIALIASING,RenderingHints.VALUE_TEXT_ANTIALIAS_ON);
area.paint(g);
g.dispose();
ImageIO.write(image, "jpeg", toSave);

A robot wouldn't do what the OP wanted: with antialiasing, etc...
I'm still not convinced that ImageIcons don't get saved. Why does this code work:
import java.awt.*;
import java.awt.event.*;
import java.awt.image.*;
import java.io.*;
import java.net.*;
import javax.imageio.*;
import javax.swing.*;
public class X {
    public static void main(String[] args) throws IOException {
        final JPanel p = new JPanel();
        p.add(new JLabel(new ImageIcon(new URL("http://today.java.net/jag/bio/JagHeadshot-small.jpg"))));
        p.add(new JLabel(new ImageIcon(new URL("http://java.sun.com/placeholders/duke_swinging.gif"))));
        p.add(new JLabel("etc"));
        JButton save = new JButton("save");
        save.addActionListener(new ActionListener(){
            public void actionPerformed(ActionEvent evt) {
                save(p, new File("junk.jpeg"));
        JFrame f = new JFrame("X");
        f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        Container cp = f.getContentPane();
        cp.add(p);
        cp.add(save, BorderLayout.SOUTH);
        f.pack();
        f.setLocationRelativeTo(null);
        f.setVisible(true);
    static void save(Component comp, File file) {
        try {
            BufferedImage image = new BufferedImage(comp.getWidth(), comp.getHeight(), BufferedImage.TYPE_INT_RGB);
            Graphics2D g = image.createGraphics();
            g.setRenderingHint(RenderingHints.KEY_FRACTIONALMETRICS,RenderingHints.VALUE_FRACTIONALMETRICS_ON);
            g.setRenderingHint(RenderingHints.KEY_TEXT_ANTIALIASING,RenderingHints.VALUE_TEXT_ANTIALIAS_ON);
            comp.paint(g);
            g.dispose();
            ImageIO.write(image, "jpeg", file);
            image.flush();
        } catch (IOException e) {
            e.printStackTrace();
}
