New to Java

Hey fellows, I have a few panels in one frame: jpAll, jpMain and jpBottom.

I'm trying to figure out how to click a button in jpBottom and update the content in jpMain?? So far the only way I've figured is to kill the current frame and open a new frame...I don't like that idea.

Currently, what I have tried for that button's event handler (jbtNext) is assigning jpMain to null and then trying whatever I thought would refresh the panel's content (repaint(), jpMain.validate, jpMain.setVisible()).

public void actionPerformed(ActionEvent e)
 {                
                if (e.getSource() == jbtNext)
                {
                    jpMain = null;
                    repaint();
                    jpMain.validate();
                    jpMain.doLayout();
                    jpMain.setVisible();

                }
}

Lastly, I tried overriding the paintComponent() method and copying some of the code above (such as jpMain.validate()), and I got the same results.

I'm having a hard time finding comprehensive work/books about GUIs. Feel free to suggest books thx.
