Bonjour à tous,
J'utilise actuellement un framework maison, qui est composé de 2 parties. La partie présentation est gérée par Flex et la partie métier est gérée en Java.
Pour le moment l'intégration Flex/BlazeDs/Spring/Hibernate fonctionne mais dans un souci d'optimisation, j'aimerais mettre en place les lazy loading, ce qui n'est pas possible avec BlazeDS. Pour cela il faut installer dpHibernate.
Voila mon problème, cela fait quelques jours que je galère à intégrer dpHibernate dans le framework.
Pour info, le serveur d'application tourne sous Tomcat et la base de donnée sous MySQL.
Version des lib :
- Hibernate 3
- Spring3
- dpHibernate 2.0 RC3
Erreur lors du lancement de Tomcat :
