Bonjour à tous,
je suis en 4éme année école d'ing.
je travaille sur le deboggage d'un projet (java,bd mysql).L'application java est déjà faite.
L'application java est censée créer une bd et se connecter à cette base.
Mais en lançant cette application il me dit que la communication entre java et la bd mysql a échoué et il m'affiche ce message:
SQLException: Communications link failure due to underlying exception:

PS: Hors ligne c'est le nom du projet.
L'application a été compilé l'année dernière et tout marchait bien alors le pb ne doit pas etre un pb de programmation.
A votre avis c'est koi la solution de ce pb.
Je vous remercie.
C'est urgent.
Merci d'avance.
