Layering Objects (That extend JComponet) on JApplet

Question

I currently have a JApplet within which I add two objects that both extend JComponet. Object A is basically a large square and object B is a small square, I need Object B to always be in front of Object A, however I cant work out how to set layering within the JApplet to do this. Current I am using the follow code, which adds both the items and displays them how I want however sometimes Object A is front of Object B.

public void init() {
    add(myapplet, BorderLayout.CENTER);
    resize(200, 400);
    B = new Block(Color.green, 10, 10);
    myapplet.add(B);
    A = new Block(Color.red, 100, 100);
    myapplet.add(A);
    myapplet.addMouseListener(this);
    startTimer();
}

You might look at JLayeredPane, seen here, or OverlayLayout, seen here. Either should work in an applet, but this hybrid approach may offer additional flexibility.

JLayeredPane

OverlayLayout

Giving a JLayeredPane a try, the applet will run but does not display anything, my init now looks like: http://pastebin.com/Bct9dVsb – Zac Powell Dec 09 '12 at 19:19
Too much missing; please edit your question to include an [sscce](http://sscce.org/) that shows your current approach. – trashgod Dec 09 '12 at 22:31

You may want to look at this method: Container.setComponentZOrder(Component comp, int index)

I added `myapplet.setComponentZOrder(B, 0); myapplet.setComponentZOrder(A, 1);` however I get `java.lang.IllegalArgumentException: component and container should be in the same top-level window` – Zac Powell Dec 07 '12 at 14:51
