Salut

j'ai des problemes au niveau de l'interaction entre ces différents framework (Hibernate+Spring+Strut).
par exemple comment faire pour intégrer hibernate dans spring? et d'autre part utiliser spring comme étant couche de traitements et strut pour presenter l'interface sachant que tous les deux ont meme archetecture MVC.
voila donc je n'ai pas la moindre idée sur ce sujet.et ce que je veux : des conseils ou bien des exemples si ça possible biensur.

Merci

Voila j'ai fait des progres et j'ai arrivé à integrer hibernate dans spring et j'ai testé ma couche service et tt va bien.
mais quand je commence a travailler sur strut2 la je touve des difficultés voila mes fichier de conf et les messages d'erreurs que j'obtiens:

Merci pour l'avance

[hittepit]

Je dirais a priori que ce n'est pas un problème avec Struts, mais un problème de config au niveau de Spring:

<bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
<property name="sessionFactory" ref="sessionFactory" />
</bean>

définit un Transaction Manager pour JPA, mais tu as une sessionFactory qui ne peut être injectée dedans.

Deux solutions:
1) faire du JPA au lieu de l'Hibernate (et donc avoir un EntityManagerFactory au lieu d'une SessionFactory).
2) utiliser org.springframework.orm.hibernate3.HibernateTransactionManager au lieu du JpaTransactionManager

Bonjour,

Si tu utilises JPA voici une URL reprenant un exemple :
