Make a java program run by clicking an icon

Question

Hi,
i've created a program in java, but how can i start such a program in windows like a normal program?
I only know how to start it from inside JCreator, but i heard you could use a .bat file to do this.
Does anyone knows more about this?
any help would really be appreciated!!

Answer 1

If the dos box disapears too fast, try
java Main
pauseYou can start applications whith doubleclick which have a window (they are started with javaw instead of java).
1. step:
Write a simple class in a package (e.g. "test"):
// HelloWindow.java
package test;
import javax.swing.*;
public class HelloWindow extends JFrame {
     public static void main(String[] args) {
          new HelloWindow();
     public HelloWindow() {
          super("Hello");
          setDefaultCloseOperation(EXIT_ON_CLOSE);
          JLabel lab = new JLabel("Hello");
          getContentPane().add(lab, "North");
          setVisible(true);
          pack();
}and compile this class.
2. step:
Write a text file HelloWindow.man:
Main-Class: test.HelloWindowThe line has to end with a NEWLINE (RETURN).
3. step:
Now you have following files:
anyDirectory
  |--- test
  |      |--- HelloWindow.java
  |      |--- HelloWindow.class
  |--- HelloWindow.manGo in the console into the directory "anyDirectory" and write
jar cfm Hello.jar HelloWindow.man testNow there should be a file "Hello.jar" in this directory.
You can start your application with doubleclick on this jar-file!
