Débutant JSF: Probleme avec Managed Bean (JSF)..
Bonjour à tous,
J'utilise Netbeans 6.1 + Glassfish v2 + JSF
Ma question: A part face-config et sun-web.xml créé comme décrit ci-dessous, y a t-il un paramétrage à faire avant d'utiliser un ManagedBean?
Merci du temps consacré à me répondre.
==============
J'ai fait une page evaluations.jsp ou j'utilise un bean managé evaluationController
pour afficher les lignes d'une table de BD dans un tableau.
ce bean est déclaré dans face-config.xml comme suit:
Code:
1
2
3
4
5
| <managed-bean>
<managed-bean-name>evaluationController</managed-bean-name>
<managed-bean-class>com.petrone.controller.EvaluationController</managed-bean-class>
<managed-bean-scope>session</managed-bean-scope>
</managed-bean> |
