. Sans connaitre votre application en arrière plan, est-ce que JNA (réputé plus facile à gérer) ne serait pas une solution acceptable pour lui. En "gros", JNA permet d'appeler des méthodes native sans avoir besoin d'écrire un code spécifique coté natif (on charge une librairie, on appel la méthode X de cette librairie). A voir donc
