Question

How to run a Java game (.jar file)?

Answer 1

I use NetBeans, similar to Eclipse. You have to designate the class that contains the main() and then Eclipse or NetBeans writes the ANT script that writes the Manifest file in the .jar. Something like:

jarname.MainFrame.main



You can use the .jar tool included in the JDK, but that is two files with 3 arguments using the command-line.

Answer 2

I think you haven't Set ENTRY POINT for jar (Main Class) Take a look:

Answer 3

You need a manifest file that is named

META-INF/MANIFEST.MF



This manifest must contain a line as follows

Main-Class: MyPackage.MyClass



Where MyPackage and MyClass are the packages and class that contain the main method.



Have fun.
