Bonjour,

J'ai une appli java dont le principe est, entre autres, de se connecter à une BDD (Oracle 10g ou 11g selon les jours, ca change quelque chose ?).

Pour les tests, j'utilise ma base Oracle XE locale, tout marche très bien.

Ensuite, la base que j'utilise est une base Oracle 11g hébergée sur un ordinateur classique sous windows XP. Le nom de la base est normalement le bon (colonne Name de la requête SELECT * FROM V$DATABASE), le port 1521 est ouvert en tcp et en udp dans le pare-feu windows, le nom du serveur est bien celui que j'ai récupéré dans le "à propos" de la base.
Mes logs sont normalement corrects, puisque c'est ceux que j'utilise pour accéder à Oracle Application Express.

Et pourtant, je n'arrive pas à me connecter à la base. Lorsque le port 1521 n'était pas encore ouvert, j'avais une UnknownHostException et une Connection timed out. Maintenant qu'il est ouvert, je vous laisse regarder :

La base tourne pourtant.

Ces erreurs disent-elles quelque chose à quelqu'un ?

EDIT : Je viens de vérifier, le listener semble activé, l'erreur vient donc probablement pas de là.
