[new_2_java]

Here's what you need to do:

1. You should have a Manifest.mf file, which will contain the following lines.

I am using HelloWorld.java as example.

Code:

Main-Class: your.package.HelloWorld

NOTE: Make sure you hit ENTER at the end of the line (Manifest.mf file).

2. Next create your jar file, as follow:

Code:

>jar cmf Manifest.mf hello.jar *.*

That's it. You can run it by double clicking on it and or as follow:

Code:

>java -jar hello.jar
