Hibernate saveOrUpdate() nullPointerException lancé à chaque seconde mise à jour

Question

J'ai un problème avec le code d'hibernation. J'appelle la méthode saveOrUpdate() et chaque fois que j'essaie de faire une mise à jour, j'obtiens une exception NullPointerException. La première fois ça marche, la deuxième fois non, la troisième fois. Cela se passe sur les mises à jour. Je ne rafraîchis pas la page, republiant le serveur, rien. Voici mon code. L'exception est levée sur la session. GetTransaction(). Commit(); ligne.

Session session = getSession(); 
session.beginTransaction(); 
session.saveOrUpdate(com); 
session.getTransaction().commit(); 

J'ai essayé de faire session.flush() et session.close() après la validation, mais cela n'aide pas.

Toute aide serait vraiment appréciée.

Et voici la trace de la pile ....

Quelle est la version du pilote JDBC Oracle utilisez-vous?

Ceci était un problème connu avec ojdbc14.jar pour Oracle 9. Téléchargez le dernier pilote JDBC pour votre plate-forme et il devrait disparaître.
