Looks like you're missing proper video card drivers. Depending on your video card, you can download drivers here:

http://www.nvidia.com/

http://ati.amd.com/

http://downloadcenter.intel.com/

I don't think, games work fine… but i'm trying to update driver this night

Games probably work fine because they use DirectX, but an OpenGL implementation must be provided by the driver for OpenGL programs to work.

5

Do you have the 64-bit version of LWJGL.dll?

6

LWJGL2.1 supports 64 bit for all platforms. The latest SVN version of jME2 and jME3 use LWJGL2.1.

Solved !!



It was my drivers. I dowloaded drivers from nvidia web site and install it fix my problem.

Work like charm in 32 & 64 bits versions :slight_smile:



Thank !
