envoi d'un mail automatiquement
Bonjour à tous,
Je termine l'application que j'ai du réaliser pendant mon stage, et je dois régler les derniers détails. Devant faire un intranet, ayant coder les mots de passe en md5, je souhaiterais pouvoir faire une fonctionnalité permettant de récupérer un nouveau mot de passe en cas de perte. Je demande donc l'identifiant et l'adresse mail de l'utilisateur, et je souhaiterais lui envoyé un mail automatiquement avec ce nouveau mot de passe. Voila la classe que j'ai telecharger :

Je ne parviens cependant pas a comprendre comment utiliser ce service testMailService dans ma servlet :cry: .
Si quelqu'un a une idée, je le remerci d'avance !!
