Thrown if the Java Virtual Machine cannot find an appropriate native-language definition of a method declared native.

il a bien trouvé ta dll, mais la méthode en question (native) n'est pas implémentée: "void maMethode(java.util.ArrayList)"

effectivement, J ai change le nom de la classe, ce qui fait la signature de ma methode avait ete change, ce qui veut dire que je devais la changer dans le fichier cpp
