Hi
I’m working on a Connect 4 online game for my studies.
I’m trying to make an applet with jmonkey to integrate it in the game website.
The applet worked yersteday, but tonight it mysteriously does not want to start, whereas I didn’t make hudge changes in my code.
The webstart doesn’t work too but the .jar and windows .exe runs fine.
I’m a kind of newbie with jMonkey and I really don’t see where the problem is.
Could you help me ?
my whole jme project is here (dist and assets included) :
http://puissance4.olympe-network.com/Power4.zip
And here, just my 3 java classes.

You can see my french comments in my code
