Java SE (Java Platform, Standard Edition)

Hi,
I am using JDateChooser in an Applet. The applet loads well and display the date chooser and pop up date picker calendar well but when I click on the Pop-up Calendar the date is not selected.

It works well in the applet viewer but not in IE.

I am using JDateChooser from JCalendar packate http://www.toedter.com/en/jcalendar/

This is a simplified code that has the same behavior as my original.

import java.applet.Applet;
import java.awt.*;
import java.awt.event.MouseEvent;

import javax.swing.*;
import com.toedter.calendar.JDateChooser;

public class JCalendarApplet extends Applet {

	JDateChooser chooser = new JDateChooser();
	
	JPanel panel = new JPanel();
	JLabel label = new JLabel();
	JButton button = new JButton();
	
	public JCalendarApplet()
	{		
	}
	
	public void init()
	{
		try {
			label.setText("Hello there");
			button.setText("Update");
			button.addMouseListener(new Button_Update_mouseAdapter(this));
			panel.setSize(800,800);
			panel.add(label);
			panel.add(chooser);
			panel.add(button);	
			add(panel);
			
			
		}catch(Exception e)
		{
			e.printStackTrace();
		}
	}
	public void updateLabel(MouseEvent e)
	{
		label.setText(chooser.getDate().toString());		
	}
}

class Button_Update_mouseAdapter extends java.awt.event.MouseAdapter {
	  JCalendarApplet adaptee;

	  Button_Update_mouseAdapter(JCalendarApplet adaptee) {
	    this.adaptee = adaptee;
	  }
	  public void mouseClicked(MouseEvent e) {
	    adaptee.updateLabel(e);
	  }
}

Expected behaviour is:
1) When click on date chooser, date picker pops up
2) When click on date picker calendar to select a date date is selected
3) When click on button date is displayed from JDateChooser

Current behaviour is:
1) When click on date chooser, date picker pops up
2) When click on date picker calendar to select a date, date picker pop up screen closes and new date is not selected.
3) When click on button, previous date is displayed.

Environment:
jar files are setup and I am running it on a web-sphere server.

I would really appreciate any help. I've search the forums but could not find any clues.

Regards,
DT
