À partir de l'exception, validationQuery spécifié dans votre configuration DBCP Commons n'est pas valide dans Oracle.

D'accord. La requête de validation est normalement quelque chose sur le modèle de SELECT 1 FROM DUAL; – pjp

je change la validationQuery à "SELECT 1 + 1" mais obtenant toujours la même erreur. quelle validationQuery dois-je utiliser pour Oracle? – cometta

'select 1 from dual' comme suggéré par pjp ci-dessus devrait fonctionner correctement pour Oracle. Si vous recevez toujours une erreur, cela doit être autre chose - êtes-vous sûr que c'est la même erreur? – ChssPly76

On dirait que vous avez un problème de connexion à la base de données.

Vous devez vérifier vos urls de connexion ...
Si tout semble bien, j'entrez les mêmes données de connexion dans un outil de base de données, pour vérifier si l'outil peut se connecter.

La plupart du temps, deux étapes doivent trouver 90% de tous les problèmes de connexion.
