J'ai tenter de modifier les paramètre maxwait, maxidle et maxactive dans mon hibernate.cfg.xml mais sans succès.

MySQL 4.1
Tomcat 5.5
DBCP
Hibernate version: 3.0
Mon datasource est bien configuré dans \META-INF\context.xml cette config fonctionne car je l'ai testé dans une autre application sans utiliser hibernate.
Voici mon code dans ma classe helper pour Hibernate:
