I found this post while doing a Yahoo search and tried this with no luck it tells me I cannot set a static reference to a non static method dispose()

maybe Im setting it up the wrong way but in someway I need to have an exit button for a form for a practice test and my teachers says that dispose should work. belows the code for the button. It is a default frame using Eclipse 3.2.2 through its visual editor and 1.6_5Update of java sdk(the newest one at the time)

Code:

private JButton getJButtonexit() {
		if (jButtonexit == null) {
			jButtonexit = new JButton();
			jButtonexit.setBounds(new Rectangle(267, 199, 106, 33));
			jButtonexit.setText("Exit Frame");
			jButtonexit.addActionListener(new java.awt.event.ActionListener() {
				public void actionPerformed(java.awt.event.ActionEvent e) {
					System.out.println("actionPerformed()"); // TODO Auto-generated Event stub actionPerformed()
				frame.dispose();
				}
			});
		}
		return jButtonexit;

Sounds like there may be trouble with a static modifier somewhere.
I would want to look at the exact exception wording.
If I mistakenly capitalized the "frame" reference, viz, Frame.dispose(); then I'd get this compile error:

Code:

C:\jexp>javac test.java
test.java:12: non-static method dispose() cannot be referenced from a static context
                Frame.dispose();
                     ^
1 error

Code:

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;

public class Test {
    JFrame frame;

    public Test() {
        JButton button = new JButton("exit");
        button.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent e) {
                frame.dispose();
            }
        });
        JPanel panel = new JPanel();
        panel.add(button);
        frame = new JFrame();
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.add(panel);
        frame.pack();
        frame.setLocation(200,200);
        frame.setVisible(true);
    }

    public static void main(String[] args) {
        new Test();        
    }
}

Hardwired I seem to have found my solution for whatever Eclipse won't allow me to do "frame." and I saw some other post that simply did "setVisible(false); and just plain dispose(); I have 1_6_05 so maybe they do it differently.
Its probably like the new stuff my teacher telling us about generic functions that are supposedly not in earlier versions of Java and supposed to do allot of stuff if you can understand them under your belt.
I thank you for your response "hardwired"
