Bonjour, j'ai le même problème. Je n'arrive pas à réutiliser la classe Authenticator pour que je puisse me loger en vérifiant les informations dans ma base de donnée. Mon code est précisément le même.
Si la réponse a été découverte, merci de me la faire par.
Cordialement
Olive

en

Code :

@Out(required = false)

C'était indiqué dans la trace de l'exception

Code :
