Erreur:org.hibernate.exception.JDBCConnectionException: could not execute query

Version imprimable

Bonjour,

J'ai développé une application web (JSF,Hibernate,Primefaces,Mysql).
J'ai exporté le projet en un fichier war, et je le met dans le serveur. Le problème c'est que je doit redémarrer le serveur(machine) pour pouvoir accéder à l'application, c'est un dépannage. La page d’accueil qui contient l'authentification s'affiche toujours mais le problème qu'on peut pas dépasser l'étape d'authentification.
dans le dossier (logs) du serveur tomcat, voici l'erreur suivante:

peux-tu faire un test en remplaçant @serveur par l'adresse IP de ton serveur MySql ?

12/12/2014, 11h37
OButterlin

C'est le problème standard avec MySQL qui coupe les liens inactifs au bout de 8h (par défaut)
Pour palier à ça, tu peux :

- augmenter la durée dans les paramètres de MySQL
- passer par un pool de connexions c3p0
- utiliser le paramètre ?autoReconnect=true (marche pas toujours)

Il y a aussi la possibilité de tester la connexion si elle est gérée par un pool serveur en ajoutant une requête de test du genre "select 1"

Bonjour,

Merci plawyx, mais l'adresse IP du serveur est celle de l'adresse IP du serveur MySql.

Merci OButterlin pour votre aide.
En fait, j'ai mis le paramètre autoreconnect=true

mais le problème est le même.

Comment je peux augmenter la durée dans les paramètres de MySql?

JE vais essayer le pool de connexion c3p0.

Merci encore une fois.

En augmentant les paramètres, tu ne fera que déplacer le problème: au lieu de redémarrer tous les matins parce que la connexion s'est perdue la nuit, tu devra rédémarrer tous les lundis parce qu'elle s'est perdue le week-end? Vu que tu es dans une web application, je passerais par un pool de connexions gérés par le conteneur tomcat, et je configurerais ce pool pour faire de l'autoreconnect lui même. Je ne vois pas trop l'intérêt de gérer soit même la connexion dans une application web, ça limite les possibilités pour le client de faire la configuration.

Merci tchize_.
J'ai essayé le pool de connexion c3p0: j'ai ajouté les deux jar: hibernate-c3p0-3.6.0.Final.jar et slf4j-nop-1.7.3.jar, et j'ai modifié le fichier hibernate.cfg.xml:
