Erro com JNativeHook

Programação Java
#1

estou executando o codigo abaixo no eclipse juno com java 1.6.37 e windows 7 ultimate


import org.jnativehook.GlobalScreen;
import org.jnativehook.NativeHookException;
import org.jnativehook.keyboard.NativeKeyEvent;
import org.jnativehook.keyboard.NativeKeyListener;

public class GlobalKeyListenerExample implements NativeKeyListener {
        public void nativeKeyPressed(NativeKeyEvent e) {
                System.out.println("Key Pressed: " + NativeKeyEvent.getKeyText(e.getKeyCode()));

                if (e.getKeyCode() == NativeKeyEvent.VK_ESCAPE) {
                        GlobalScreen.unregisterNativeHook();
                }
        }

        public void nativeKeyReleased(NativeKeyEvent e) {
                System.out.println("Key Released: " + NativeKeyEvent.getKeyText(e.getKeyCode()));
        }

        public void nativeKeyTyped(NativeKeyEvent e) {
                System.out.println("Key Typed: " + e.getKeyText(e.getKeyCode()));
        }

        public static void main(String[] args) {
                try {
                        GlobalScreen.registerNativeHook();
                }
                catch (NativeHookException ex) {
                        System.err.println("There was a problem registering the native hook.");
                        System.err.println(ex.getMessage());

                        System.exit(1);
                }

                //Construct the example object and initialze native hook.
                GlobalScreen.getInstance().addNativeKeyListener(new GlobalKeyListenerExample());
        }
}

se eu rodar o projeto no eclipse, o codigo funciona sem erros

se eu gerar um jara executavel com o FATJAR e One-JAR obtenho o seguinte erro:


JarClassLoader: Warning: Unable to load native library: java.lang.NullPointerExc
eption
Exception in thread "Thread-0" java.lang.NoClassDefFoundError: Failed to locate
the org.jnativehook.mouse.NativeMouseWheelEvent class
There was a problem registering the native hook.
Failed to create JNI global references

alguem pode me ajudar a resolver ?
