Add other components to JFrame with background

Question

I want to add a background image to my JFrame but when I do it using the code below, I'm unable to add other elements like JLabel or JTextField.

ImageIcon icon = new ImageIcon("src/images/back.jpg");
backImage = icon.getImage();
BackgroundImagePanel contentPane = new BackgroundImagePanel();
contentPane.setBackgroundImage(backImage);
this.setContentPane(contentPane);

Can you tell me please if there is another way to add JTabbedPane to a JFrame with a background ?

Thank you.

Addendum: "Normally you would invoke super.paintComponent(g) first, but since the image will cover the entire background there is no need to do this."—camickr

Addendum: See also the opacity property.

    private static class ImagePanel extends JPanel {

        BufferedImage img;

        ImagePanel(String name) {
            this.setToolTipText(name);
            this.add(new JLabel(name));
            try {
                img = ImageIO.read(new File(name));
                this.setPreferredSize(new Dimension(
                    img.getWidth(), img.getHeight()));
            } catch (FileNotFoundException e) {

            } catch (IOException e) {
                e.printStackTrace();

        @Override
        protected void paintComponent(Graphics g) {
            // super.paintComponent(g);
            g.drawImage(img, 0, 0, this.getWidth(), this.getHeight(), null);
        }
    }
}

nitpicking Monday again :-) a) super(true) is redundant, panel is double-buffering by default b) even when covering everything, it might have transparent areas - so not calling super is complying to super's contract only if opaque == false. which it isn't by default and can be changed by client code at any time. So it's not really safe, and letting your IDE type one additional line is ... :-) — kleopatra, Dec 05 '11 at 10:43

Try adding this:

//4. Size the frame.
this.pack();

//5. Show it.
this.setVisible(true);
