DaniWeb IT Discussion Community - Working with JLayeredPane and positioning of components.. HELP!

HELP.. I have a frame set to the screen size of my monitor, background color is yellow. I have a panel returned by midFrame() (outerPanel) supposed to be located at the center of my frame. i used the setBounds() to place my panel in the center but it doesn't do so.. and i have an inner panel with 2 more panels (a header and view panel) in it. the view panel is where i used the JLayeredPane so i could put components on top of each other-- a background image(using JLabel) and another panel(with buttons and more components). but i don't seem to add the components in the JLayeredPane correctly. what's wrong with my code? i hope you could help me.. parts of my code is included..

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

class Frame extends JFrame {

//variables
Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
Dimension frameSize = new Dimension(640,600);

//constructor
public Frame() {
JPanel mainPanel = new JPanel();
mainPanel.setBackground(new Color(255,255,158)); //pale yellow

mainPanel.add(midFrame());
getContentPane().add(mainPanel);

//frame attributes
setTitle("PicPuzz");
setSize(screenSize);
setUndecorated(true);
show();
}

//middle frame
public JPanel midFrame() {

JPanel outerPanel = new JPanel();
outerPanel.setBackground(new Color(129,220,254)); //pale blue

//centers middle frame
Point origin = new Point(0,0);

if (frameSize.height > screenSize.height)
frameSize.height = screenSize.height;
if (frameSize.width > screenSize.width)
frameSize.width = screenSize.width;

origin.x = (screenSize.width - frameSize.width) / 2;
origin.y = (screenSize.height - frameSize.height) / 2;
outerPanel.setBounds(origin.x, origin.y, 640,600);
//create inner panel
JPanel innerPanel = new JPanel(new BorderLayout());
JPanel headerPanel = new JPanel();
JLayeredPane viewPanel = new JLayeredPane();

JLabel headerlbl = new JLabel(new ImageIcon("../bg/header.png"));
JLabel viewlbl = new JLabel(new ImageIcon("../bg/bg_view.png"));

viewPanel.setOpaque(true);

headerPanel.setBackground(new Color(128,255,128)); //light green
viewPanel.setBackground(new Color(128,255,128));
headerPanel.add(headerlbl);
viewPanel.add(viewlbl, new Integer(0)); //this doen't seem to work
viewPanel.add(shapePanel(), new Intger(1));

innerPanel.add(headerPanel, BorderLayout.NORTH);
innerPanel.add(viewPanel, BorderLayout.CENTER);
innerPanel.setBounds((origin.x+20), (origin.y+20), 600,500);
outerPanel.add(innerPanel);
return outerPanel;
}

public static void main(String[] args) {
System.out.println("Frame.java");
new Frame();
}
