prolem while calling javascript method from applet in Netscape6.2

I am trying to call javascript method in java(in my applet)
here i wrote the jsp page and i used
<jsp

lugin> tag for applet. This is working fine with IE6.0 and Netscape4.6. but with the latest version of Netscape(6.2) i am getting the following exception
netscape.javascript.JSException: JSObject.getWindow() requires mayscript attribute on this Applet at java.lang.reflect.Constructor.newInstance(Native Method) at sun.plugin.liveconnect.PrivilegedConstructObjectAction.run(Unknown Source)
at java.security.AccessController.doPrivileged(Native Method)at sun.plugin.liveconnect.SecureInvocation.ConstructObject(Unknown Source)
I am adding my applet code and jsp code.
In my applet there is button, by clicking the button it will calls the javascript method and closes the browser window.
Applet class:
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
import netscape.javascript.JSObject;
import netscape.javascript.*;
import javax.swing.colorchooser.AbstractColorChooserPanel;

public class JSoTest extends JApplet implements ActionListener
{
JButton btn;
JPanel p1;
Color clr;
public JSoTest()
{
init();
}
public void init()
{
btn=new JButton("Close");
btn.addActionListener(this);
clr=Color.green;
p1=new JPanel();
this.getContentPane().setLayout(new BorderLayout());
getContentPane().add(p1,"Center");
getContentPane().add(btn,"South");
p1.setBackground(clr);
}
public void actionPerformed(ActionEvent e)
{
try{
JSObject obj=JSObject.getWindow(this);
obj.call("close",null);
}
catch(Exception ex)
{
ex.printStackTrace();
}
}
}

jsp page:

<html>
<head>
</head>
<body >
<jsp

lugin type="applet" code="JSoTest.class" codebase="/examples/jsp/plugin/applet/"
jreversion="1.3"

<p>Unable to load java plugin</p>
</jsp:fallback>

If i write the html file and with embed tag it is working fine.

A Google search on "+java +applet +mayscript +javascript" gave me this as the first match:
http://java.sun.com/products/plugin/1.3/docs/jsobject.html
Just search the page for 'mayscript'.
