I've made a game that works fine within Eclipse. But, it won't run when I double click the icon, and when I run it through cmd, I get the following:

Code:
C:\TakeFlight>java -jar TakeFlight.jar

Could not find the main class: george.game.takeflight.Game. Program will exit.


I'm not sure why it can't find StateBasedGame, as I've directed the path to the Slick folder and it's having no problems with the lwjgl jar ... Any ideas?

Thanks!

It seems it can't find your main class either "Could not find the main class: george.game.takeflight.Game"

What did you use to build it? JarSplice?

I used Eclipse to export the jar, I don't really understand why it can't find the main class... D:

if you open the jar with winzip or winrar, do you find back your class?

Google is my best friend :wink:

Ah, thankyou very much, that solved the problem with the main class! :D

Unfortunately the problem with StateBasedGame persists :/

This means you didn't set your class-path for the JAR, or that it can't find "slick.jar" within the set class-path.

You could also try putting the dependencies in the same folder. But you'll also need a "-Djava.sun.library" flag for the natives -- i.e. a batch script, or terminal shell file.

Better to just use JarSplace if you want a simple way to distribute a game...

THANKYOU SO MUCH!!!!!!!!!!!!1111eleven

I think you may have just saved my sanity. JarSplice was ridiculously easy to use too. Fan-freakin'-tastic.

:D
