Problème avec les beans

Version imprimable

bonjour chers développeurs,
Je developpe une application Java EE avec Spring pour l'IOC,JSF 2.2 et PrimeFaces 3.5 et JBoss 7.1.
Le probleme c'est avec JSF,qui me renvoi l'exception:"Target Unreachable, identifier 'carb' resolved to null:"
J'ai cherché sur google et tous les forum,aucune solution proposée n'a resolu mon probleme. alors je voudrais avoir des indication sur les causes possibles .
Merci

carb normalement doit être ton managed bean que tu n'as pas configuré dans le facesConfig normalement

Bonjour,
Tu n'etais pas loin de son erreur, en effet tout est dit ici :

Code:

value="#{carb.typeCarburant.idCarburant}": Target Unreachable, identifier 'carb' resolved to null

Depuis JSF2 la déclaration des ManagedBean peut se faire directement par annotation au dessus de la classe en question.Il faut plutot qu'il nous montre l'entête de la classe ManagedBean qu'il réferencait dans cette variable :

Code:

carb

merci pour vos reponses, au fait j'ai effectué le changement suivant
Code:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 import org.springframework.beans.factory.annotation.Autowired; import org.springframework.context.annotation.Scope; import org.springframework.stereotype.Component; import project.metier.mouse.TypeCarburant; import project.service.TypeCarburantService; @Component @Scope //@ManagedBean(name="carb") public class TypeCarburantBean { private TypeCarburant typeCarburant; private TypeCarburantService carburantService; public void addTypeCarburant(){ carburantService.addTypeCarburant(typeCarburant); } public TypeCarburant getTypeCarburant() { return typeCarburant; } public void setTypeCarburant(TypeCarburant typeCarburant) { this.typeCarburant = typeCarburant; } @Autowired public void setCarburantService(TypeCarburantService carburantService) { this.carburantService = carburantService; } public TypeCarburantBean(){ } }
et l'erreur a changé.

Bonjour,

Essaie ça :
Code:

1 2 @ManagedBean(name="typeCarburantBean")
Et laisse ton fichier xhtml tel quel.
en fait les Beans etaient dejà reconnus,au final ce que j'ai changé c'est
Code:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 package project.metier.dao; import java.util.List; import org.hibernate.Criteria; import org.hibernate.Query; import org.hibernate.Session; import org.hibernate.criterion.Expression; import org.springframework.stereotype.Repository; import project.metier.mouse.TypeCarburant; import project.util.HibernateUtil; @Repository("iTypeCarburantHome") public class ITypeCarburantImpl implements ITypeCarburantHome {
le @repository en mettant la première lettre en minuscule(iTypeCarburantHome) et ça marche

Merci à vous
