2 paintcomponents in 2 Jpanels

Question

Hello all,
i am working via the model view controller method...
My situation is that i want swimmers to swim in a swimming pool.
I have a class SwimmingpoolView and a class Swimmerview they are both JPanels
now am i using in both classes
*public void paintComponent  { }*
The swimmers must move in the swimming pool i do that by decresing the Y as. But when i decrese the Y as the swimmer multiply.
To solve that i went to the swimmerview class and added by the paintComponent "super.paintComponent(g)" .
Well it seems to work :) there are no multiple swimmers. But now my swimming pool is gone what happend????
I will post my files ..
SwimmingPool.java
{code}package zwembad;
import java.awt.*;
import javax.swing.*;
import java.awt.event.*;
public class ZwemmerView extends JPanel {
private Zwemmer zwemmer;
/** Creates a new instance of ZwemmerView */
public ZwemmerView (Zwemmer zwemmer) {
this.zwemmer = zwemmer;
public void paintComponent (Graphics g)
zwemmer.tekenZwemmer(g);
{code}
*Swimmer.java*
{code}package zwembad;
import javax.swing.*;
import java.awt.*;
public class ZwembaanView extends JPanel{
private Zwembaan zwembaan1;
/** Creates a new instance of ZwembaanView */
public ZwembaanView (Zwembaan zwembaan1)
this.zwembaan1 = zwembaan1;
if(zwembaan1.getAantalBanen() == 7)
JOptionPane.showMessageDialog(ZwembaanView.this,"Niet meer dan 7 zwemmers zijn toegestaan in het Zwembad","Foutmelding",JOptionPane.ERROR_MESSAGE);
public void paintComponent (Graphics g)
super.paintComponent (g);
// teken het zwembaden
          zwembaan1.tekenZwembad(g);
}{code}
What happend?
Thank you

I already have that. this portion works.
what I want is when I call the main number on CME1 ex: 123 456 7890 and autoattendant takes over, when I try to reach a 41xxx extension it tells me INVALID NUMBER.
so: hello welcome to xyz if you know your parties ext dial it now.
if I do 2xx extension it works but if I do 41xxx it says invalid number.
