displaying an image from a file chooser

Question

I am having problems displaying an image I obtain from a file chooser I created. Could you give me suggestions? The image is created as a buffered image.

Here is my code:

public void actionPerformed(ActionEvent e)
{
    if (e.getSource().getClass().getName().contains("JMenuItem")) 
    {
        if (e.paramString().contains("Load")) {
            JFileChooser fc = new JFileChooser();
            fc.setCurrentDirectory(new File("."));
            int retVal = fc.showOpenDialog(null);
            if (retVal == 0) 
            {
                File file = fc.getSelectedFile();
                try {
                image = ImageIO.read(file);
            } catch (IOException e1) {
                // TODO Auto-generated catch block
            e1.printStackTrace();
        }
    }
}

Here is the code for display:

public void paint(Graphics g){  
    super.paintComponents(g);
    g.drawImage(getIconImage(), 0, 0, control);
    g.drawImage( image, 0, 0,null);
    repaint();
}

what errors do you get? why are you calling drawImage twice? could you post the whole code or an SSCCE or at least the stacktrace reporting the error? — Heisenbug, Sep 10 '11 at 15:17
the think is the image does not show on my gui. I want to display the image i obtain from the file chooser to my gui. Do you want to see the code for my gui? — user938295, Sep 10 '11 at 15:19

the display code doesn't look like Swing ... in case you are mixing awt and swing - dont! — kleopatra, Sep 10 '11 at 16:07
repaint() in a paint method? Just don't do it! Myself, I like mKorbel's solution (+1) — Hovercraft Full Of Eels, Sep 10 '11 at 17:01

Why bothering with 2D Graphics for display picture(s), put Image/ImageIcon to the JLabel, example about JFileChooser + Image + paintCompoent(),

public void paint(Graphics g){// paintComponent not paint 
   super.paintComponents(g);  // paintComponent not paintComponents
.....

Could be for Swing JComponents

public void paintComponent(Graphics g){  
   super.paintComponent(g);
......
