I am lazy.

I always want to simplfy things, by making 10 functions out of 1000s.

Below is my simplifier adapter class:

            }

            @Override
            public void preExit() {
            }
        };
    }
}

and last one; Below is my exception list

The question is: Why are these exceptions happening?
I need desperate help.

TK_FileUtils...
Code:
    public static URL getURL(String string) {
        try {
            return getFileObject(string).toURI().toURL();
        } catch (Exception ex) {
            ex.printStackTrace();
            return null;
        }
    }
    public static File getFileObject(String fileOrDirectoryName) {
        try {
            return new File(fileOrDirectoryName);
        } catch (Exception e) {
        }
        return null;
    }

TK_GeneralUtils...
Code:
    public static int getScreenWidth() {
        return Toolkit.getDefaultToolkit().getScreenSize().width;
    }

    public static int getScreenHeigth() {
        return Toolkit.getDefaultToolkit().getScreenSize().height;
    }

First you need the hudthemes.jar in your classpath. And then you need OpenGL 1.3 support. I assume, your hardware is capable of that. So you should install recent drivers.

And please use a recent version of Xith3D. Please check it out from SVN. I have already ported your code to the current API. You will see, that it has become a lot simpler and shorter.
