Problème JDBC et socket

**VinceSSJ** · 13/07/2012, 17h27

Bonjour à tous,

voilà je travaille sur une application JEE qui tourne sur GlassFish.

L'application est en test en production, et tourne bien, sauf que, quelques fois, quand quelqu'un s'est connecté dessus, j'ai cette erreur qui sort de nul part et qui fait donc bugger temporairement l'appli :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

J'ai également eu ce erreurs :

Code :

GRAVE: log4j:WARN No appenders could be found for logger (org.apache.fop.util.ContentHandlerFactoryRegistry).
GRAVE: log4j:WARN Please initialize the log4j system properly.

Mais je pense pas que ce soit lié.

Voilà donc apparemment JDBC qui fait des siennes mais franchement je n'arrive pas à en trouver la source !

Des indices ?

Merci !

**Mathieu.J** · 13/07/2012, 18h38

Ta connexion tombe en timeout, ton client ne doit pas arriver à se connecter à ta base de données (Mauvaise URL ou mauvais port ?).

L'erreur LOG4J n'a rien a voir, ça veut seulement dire que ta configuration n'est pas correcte (Fichier log4j.propertes ou log4j.xml dans le classpath). Par contre ça peut t’empêcher de voir des log.

**VinceSSJ** · 15/07/2012, 23h25

Merci pour la réponse !

Pourtant l'application n'avait jamais de soucis et là du jour au lendemain j'ai eu ces erreurs (même sur l'application que je n'ai pas modifiée). Le code est pourtant bon et JDBC est à jour mais j'ai ces erreurs. L'application tourne mais voilà de temps à autres cette erreur surgit.

Je pense que l'URL est bonne, après c'est peut être au niveau des ports que ça passe moins bien..
Parallèlement à ça, l'entreprise subit une virtualisation des serveurs de bases de données, et étrangement ces erreurs ont commencé à apparaitre depuis que les serveurs ont commencé à être migrés..

Est ce que ça pourrait avoir un lien ?

**Mathieu.J** · 16/07/2012, 09h50

Il y a des chances que ça vienne de là.
L'exception peut aussi venir d'un problème réseau : bonne IP et bon port, mais machine impossible à joindre par exemple

**VinceSSJ** · 16/07/2012, 10h14

Mais dans ce cas comment savoir de quel problème précis de réseau ça vient ? Est ce qu'il y a moyen déjà de remonter le nom du serveur injoignable dans le log ?
