Unable to build EntityManagerFactory
Bonjour,
Je debute sur les JPA et je pense avoir un probleme simple sur lequel je bloque pourtant depuis trop longtemps. Mon probleme se situe au lancement simple d'une classe de base pour tester la persistence.
J'ai une base hsql qui tourne correctement:

Voici aussi mon persistence.xml:

Lorsque j'apporte une modification au persistence.xml, j'ai une erreur de plus, je presume donc que la connexion a la bd s'opere correctement.
Pourtant j'obtiens toujours la meme erreur :(:(:

Peut-etre que cette erreur vient de mon code Adresse.java:

qui sont pourtant les codes d'un tuto que je suis scrupuleusement...
Je n'ai plus d'idee pour debugger/debloquer cette erreur, j'espere que vous pourrez me guider.
Merci
