Problème lecture date taken d'une image

Bonjour communauté JAva,

Je ne parviens pas à avoir la date taken d'un fichier jpg jpeg, en java. J'ai bien trouvé un bout de code, mais celui-ci ne me renvoie pas la date taken.

Voici le bout de code.

Je voudrais bien un peu d'aide ... parce que je m'arrache les cheveux ...
