Applet help

Troubleshooting General Help
1

Hello,

i dont have much time and i need to get Applet work. I actually have here Windows 8.

Usually i dont use applet, but now i need.

Maybe i just made something stupid, or just use bad java libs.

Can i ask what can be wrong?

just a simple app

[java]
import com.jme3.app.SimpleApplication;
import com.jme3.renderer.RenderManager;

/**
*

  • @author OxPlay
    */
    public class SimpleJMETest extends SimpleApplication {

    public static void main(String args) {
    SimpleJMETest app = new SimpleJMETest();
    app.start();
    }

    @Override
    public void simpleInitApp() {
    }

    @Override
    public void simpleUpdate(float tpf) {
    }

    @Override
    public void simpleRender(RenderManager rm) {
    //TODO: add render code
    }
    }
    [/java]

console log:

I think the problem is LWJGL. You could try to update it to the latest version (2.9.0. or 2.9.1 nightly).

The first stack trace says It’s expecting to open “code.jar” as a URL. It should start with “http:” or something like that. You’d have to check where that URL came from and correct that.

The LWJGL problems might be just a consequence of that, or an independent problem.
