executable jar

[chilster]

Hello
I am trying to create an executable jar file. I create it successfully however when I double click on it,the 'open with' dialog opens up instead. Any ideas?
Cheers
code:

manifest-
Main-Class: MyClass
Classpath: .\MyJar.jar


command line
jar cvfm MyJar.jar manifest.mf MyClass.class



source:

import java.awt.*;
import java.awt.event.*;

public class MyClass {
public static void main(String[] args) {
Frame f = new Frame();

f.add(new Label("hi there&quot);
f.setSize(200,200);
f.setVisible(true);
}
}

I'm not quite sure what you mean here... A jar won't simply execute on a double-click. You need to call it from another java program (that imports the jar), call it from the command-line or build yourself a .bat/.cmd script that does the calling for you(through a command line). There's got to be builders that turn your jar into an .exe, but I've never done that (anyone out here?). To simply browse jar files, I use WinRAR.

if you are running windows, associate files with the .jar extension with the javaw executable. This should cause jar files with a main class specified to automagically execute when you double click on them.

If you really want to create an exe file check out this thread: Thread269-276852

However, I would have to agree with daniel and say that what you really want to do is have a bat file or a shell script, depending on what os you're running on, and launch the java app from there
