How to create a jar file - by Tanul Karkare:

create a file MANIFEST.MF having 2 lines:
Manifest-Version: 1.0
Main-Class: path of ur main class file..

create a folder META-INF in ur application dir.
put this MANIFEST.MF into that.

execute the command:
jar cvfm xyz.jar META-INF/MANIFEST.MF *.class

to create an executable jar file.

just that's it.


-----------


Take an example:
create a folder test(any name will do)
create a file TestJar.java in that:

import javax.swing.*;

class TestJar extends JFrame
{
public static void main(String[] args)
{
TestJar tj = new TestJar();
tj.setSize(200, 200);
tj.setVisible(true);
tj.show();
}
}

compile this file , test with java command.
it should show a window.

create a manifest file as above inside meta-inf folder (which is inside test folder) with content:-

Manifest-Version: 1.0
Created-By: Tanul
Main-Class: TestJar


execute the command inside test folder:(test.jar can be any name)
jar cvfm test.jar META-INF/MANIFEST.MF *.class

ur executable jar is ready.
double click on it and it will show u a window.

u can give this to anybody without letting him have ur source files.
