call executable jar from html/jsp

[Zahari]

hello friends,
i have a problem to call executable jar using html/jsp.

i use the same code in applet. but be nothing.

Can you post your code so we know what you really want to do in your JSP page.

[Zahari]

i have executable jar file example calculator.jar
i want to run it by called using jsp/html
i'm not using applet in my source code.

i try to use this code, but error occur "loaded applet failed"

<applet code=calculator.class
archive="calculator.jar"
width=640 height=480>
</applet>

actually in jsp/html, when the page has loaded, the executable jar must be run first.

[wsaryada]

So your calculator class is not a Java applet? That means you cannot use the applet tag to run your calculator class. Can you post your calculator class definition?

[Zahari]

class calculator
{
public static void main(String[]args)
{
new calculator();
}

public calculator()
{
//GUI code
}
}

then i convert into executable jar.(calculator.jar)
when manually doubleclick it run but
i want to call it from html/jsp.
thanks.

Well, I believe i cannot be done this way. You need to create an applet that you embed on your page or you can create a swing application and then use java webstart to distribute your application.

[Zahari]

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 : ");

myCalculator()

}


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.
