Exception in thread "main" java.lang.NoClassDefFoundError: javax/xml/bind/JAXBException
Bonjour à tous,
Je suis débutant en JEE et je travaille sur un projet dans lequel il y a ma table utilisateur. Je voudrais afficher les données de cette table mais j'ai une exception in thread "main" java.lang.NoClassDefFoundError et les solutions que j'ai trouvé ne marche pas.
