New to Java

I'm having a tough time trying to figure out how to get my JFrame to launch another JFrame that will contain a JFileChooser.

Here is my method that I thought would do it:

 private void generateChooserFrame() {
        JFileChooser chooser = new JFileChooser();
        
        chooserFrame = new JFrame("Choose a file to convert into an icon");
       
        JPanel p = new JPanel(true);
        p.add(chooser);
        chooserFrame.add(p);
        
        chooser.showDialog(p, "Attach");
        
        
        chooserFrame.pack();
        chooserFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        chooserFrame.setVisible(true);
        
        setChooserFrame(chooserFrame);
    }

But when I try this I get

cannot find symbol
symbol: method showDialog(javax.swing.JPanel, java.lang.String)
location: class JFileChooser

I based this on tutorial info I read in the Java API and at http://java.sun.com/docs/books/tutorial/uiswing/components/filechooser.html to no avail.

What am I doing wrong this time, or am I just too stupid to ever know what I did wrong?
