How to make a JFrame really fullscreen?

Question

In my Java application I try to make a JFrame really fullscreen by using this code:

public class MainFrame extends JFrame {

    private static final long serialVersionUID = 1L;

    public MainFrame() {
        super();
        this.setTitle();
        this.setUndecorated(true);

        this.setExtendedState(JFrame.MAXIMIZED_BOTH);

        this.setVisible(true);
        //this.pack();
    }
}

But on my Mac I can still see the Dock and the top toolbar of the OSX. So how can I create a JFrame that really consumes my whole screen?

EDIT I have to add that I want to call that JFrame from a eclipse plugin.

I haven't tried it yet, but Java has fullscreen API, which should meet your needs:
