Cannot get image to display in Swing on OSX

I think I'm being a bit of an idiot, given that I haven't done Swing programming in a while, but I'm trying to draw a simple image to screen, and I'm not getting what I expected

public class ImageApp {

    public static void main(String[] args) throws MalformedURLException, IOException {
        final Image image = ImageIO.read(new File("/Library/WebServer/Documents/image.gif"));

        final JPanel component = new JPanel(){

            public void paint(final Graphics g) {
                System.out.println("Drawing image "+image.getWidth(null)+" "+image.getHeight(null));
                g.drawString("hello", 0,0);
                g.drawImage(image,this.getWidth()/2,this.getHeight()/2, 100, 100, Color.blue,this);
                super.paint(g)开发者_StackOverflow社区;
            }
        };

        final JFrame frame = new JFrame();

        frame.add(component);
        frame.setSize(100, 100);

        frame.pack();
        frame.setVisible(true);
    }

}

This renders a blank window which doesn't seem to be sized to 100,100. Is there some other step I need to perform to get the graphics to appear on screen, or the size to be respected?

I'm using JDK6 on OSX 10.6

In Swing, you should override paintComponent(), not paint().

Addendum: e.g., see below. In a comment, @eugener raises an excellent point about using a JLabel as an alternative image container.

import java.awt.Dimension;
import java.awt.EventQueue;
import java.awt.Graphics;
import java.awt.Image;
import java.io.File;
import java.io.IOException;
import javax.imageio.ImageIO;
import javax.swing.JFrame;
import javax.swing.JPanel;

public class ImageApp {

    public static void main(String[] args) throws IOException {
        final Image image = ImageIO.read(new File("image.jpg"));
        EventQueue.invokeLater(new Runnable() {

            @Override
            public void run() {
                final JPanel component = new JPanel() {

                    @Override
                    public void paintComponent(final Graphics g) {
                        g.drawImage(image, 0, 0, null);
                    }

                    @Override
                    public Dimension getPreferredSize() {
                        return new Dimension(
                            image.getWidth(this), image.getHeight(this));
                    }
                };

                final JFrame frame = new JFrame();
                frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
                frame.add(component);
                frame.pack();
                frame.setVisible(true);
            }
        });
    }
}

Try this:

public class ImageApp {

    public static void main(String[] args) throws MalformedURLException, IOException {
        final Image image = ImageIO.read(new File("/Library/WebServer/Documents/image.gif"));

        final JPanel component = new JPanel() {

            @Override
            public void paintComponent(final Graphics g) {
                super.paintComponent(g);
                System.out.println("Drawing image " + image.getWidth(null) + " " + image.getHeight(null));
                g.drawString("hello", 0,10);
                g.drawImage(image, this.getWidth() / 2, this.getHeight() / 2, 100, 100, Color.blue, this);
            }
        };

        final JFrame frame = new JFrame();

        frame.add(component);
        frame.setSize(100, 100);

        frame.setVisible(true);
    }
}
