Custom event mask

Question

I have defined a custom new event:
private class MyEvent extends AWTEvent {
          public MyEvent(Object source, String msg) {
               super(source, 2000);
               this.msg = msg;               
          public String getMsg() {
               return msg;
          private String msg;
     }as you can see the id is 2000 which is bigger than AWTEvent.RESERVED_ID_MAX
Now in the constructor of my JFrame: CustomEventListener
I've added the following code:
Toolkit.getDefaultToolkit().addAWTEventListener(
                    this, 2000);I want to be able that when I call "disptachEvent" with my event the method
"eventDispatched" will be called in my code, but I don't understand
what value should I set the mask in the addAWTEventListener method.
And in general I don't understand how the correlation between masks
to events work, is there some formula that if the event's id is x then
the mask should be some multiple of x or something like that?
Here is my full application:
import java.awt.AWTEvent;
import java.awt.EventQueue;
import java.awt.FlowLayout;
import java.awt.Toolkit;
import java.awt.event.AWTEventListener;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.*;
public class CustomEventListener extends JFrame implements
AWTEventListener, ActionListener {
      * @param args
     public static void main(String[] args) {
          JFrame myFrame = new CustomEventListener();
          myFrame.setVisible(true);
          myFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
     public CustomEventListener() {
          setLayout(new FlowLayout());
          btn = new JButton("Click me");
          add(btn);
          textField = new JTextField(10);
          add(textField);
          pack();
                // what value should I use for the mask
          Toolkit.getDefaultToolkit().addAWTEventListener(
                    this, 2000);
     public void eventDispatched(AWTEvent event) {
          System.out.println("boga boga");                    
     public void actionPerformed(ActionEvent e) {
          if (e.getSource() == btn) {
               dispatchEvent(new MyEvent(this, "the button has been clicked"));
     private JButton btn;
     private JTextField textField;
     private class MyEvent extends AWTEvent {
          public MyEvent(Object source, String msg) {
               super(source, 2000);
               this.msg = msg;               
          public String getMsg() {
               return msg;
          private String msg;
}I know that I can use listeners in this example, but I don't
want to use a listener for the dispatching of my event for reasons
which are a bit hard to explain.
Thanks in advance

Hi,
First say ur Jdev Version................
U can validate in ADF in both Model and ViewLayer itself... In ViewLayer u can have Validators as regular Expression Validators
Have a look into these first....
