what is java webstart? i use java swing application to write the program.
if i used java applet how can i convert it to executable jar file?

myCalculator.java

import javax.swing.*;
import java.awt.*;
import java.awt.event.*;

public class myCalculator extends JFrame implements ActionListener
{
JLabel jlbNo1 = new JLabel("Nombor Pertama : ");
JLabel jlbNo2 = new JLabel("Nombor Kedua : ");
JLabel jlbResult = new JLabel("Keputusan : ");

JTextField jtfNo1 = new JTextField(20);
JTextField jtfNo2= new JTextField(20);
JTextField jtfResult = new JTextField(20);

JButton jbtTambah = new JButton();
JButton jbtTolak = new JButton();
JButton jbtDarab = new JButton();
JButton jbtBahagi = new JButton();

JMenu jmnFail = new JMenu("Fail");
JMenu jmnOps = new JMenu("Operasi");

JMenuItem jmiKeluar = new JMenuItem("Keluar");
JMenuItem jmiTambah = new JMenuItem("Tambah");
JMenuItem jmiTolak = new JMenuItem("Tolak");
JMenuItem jmiDarab = new JMenuItem("Darab");
JMenuItem jmiBahagi = new JMenuItem("Bahagi");


myCalculator()
{
Container bekas = getContentPane();
bekas.setLayout(new BorderLayout(5,10));
bekas.setBackground(Color.blue);

JMenuBar jmb = new JMenuBar();
setJMenuBar(jmb);

jmb.add(jmnFail);
jmb.add(jmnOps);

jmnFail.add(jmiKeluar);
jmnOps.add(jmiTambah);
jmnOps.add(jmiTolak);
jmnOps.addSeparator();
jmnOps.add(jmiDarab);
jmnOps.add(jmiBahagi);
jmiKeluar.setIcon(new ImageIcon("C:/gambar/keluar.gif"));

jmnFail.setMnemonic('F');
jmnOps.setMnemonic('O');
jmiKeluar.setMnemonic('K');
jmiTambah.setMnemonic('M');
jmiTolak.setMnemonic('T');
jmiDarab.setMnemonic('D');
jmiBahagi.setMnemonic('B');

jbtTambah.setToolTipText("Adding Number");
jbtTolak.setToolTipText("Substracting Number");
jbtDarab.setToolTipText("Multiplying Number");
jbtBahagi.setToolTipText("Dividing Number");

JPanel jplInput = new JPanel();
jplInput.setLayout(new GridLayout(2,2));
jplInput.add(jlbNo1);
jplInput.add(jtfNo1);
jplInput.add(jlbNo2);

JPanel jplButang = new JPanel();
jplButang.setLayout(new GridLayout(1,4,20,20));
jplButang.add(jbtTambah);

//jplResult.add(jtaOutput,BorderLayout.SOUTH);

bekas.add(jplInput, BorderLayout.NORTH);
bekas.add(jplButang, BorderLayout.CENTER);
bekas.add(jplResult, BorderLayout.SOUTH);


//Register
jtfNo1.addActionListener(this);
jtfNo2.addActionListener(this);
jtfResult.addActionListener(this);

jbtTambah.addActionListener(this);
jbtTolak.addActionListener(this);
jbtDarab.addActionListener(this);
jbtBahagi.addActionListener(this);

jmiKeluar.addActionListener(this);
jmiTambah.addActionListener(this);

jmiBahagi.addActionListener(this);
}

public void actionPerformed(ActionEvent e)
{
int n1,n2,hasil=0;

if(e.getSource()==jbtTambah || e.getSource()==jmiTambah)
{
n1=Integer.parseInt(jtfNo1.getText().trim());
n2=Integer.parseInt(jtfNo2.getText().trim());
hasil=n1+n2;
jtfResult.setText(new Integer(hasil).toString());
}

if(e.getSource()==jbtTolak || e.getSource()==jmiTolak)
{

n2=Integer.parseInt(jtfNo2.getText().trim());
hasil=n1-n2;
jtfResult.setText(new Integer(hasil).toString());
}

if(e.getSource()==jbtDarab || e.getSource()==jmiDarab)
{
n1=Integer.parseInt(jtfNo1.getText().trim());
n2=Integer.parseInt(jtfNo2.getText().trim());
hasil=n1*n2;
jtfResult.setText(new Integer(hasil).toString());
}

if(e.getSource()==jbtBahagi || e.getSource()==jmiBahagi)

hasil=n1/n2;
jtfResult.setText(new Integer(hasil).toString());
}

if(e.getSource()==jmiKeluar)
System.exit(0);

}


public static void main(String args[])
{
myCalculator bingkai = new myCalculator();
bingkai.setTitle("KALKULATOR SAYA");
bingkai.setSize(500,400);
bingkai.setVisible(true);
bingkai.setDefaultCloseOperation(bingkai.EXIT_ON_C LOSE);

}
}

then i change it to executable jar. i want to run it by calling from html/jsp.
