Bonjour,

Je suis entrain de développer une application JEE  qui permet la gestion des interventions. Dans ce cadre j'ai développer une classe bean qui permet de créer un agenda des interventions. Lors de l'exécution de la page jsf cette erreur se déclenche: 

com.sun.faces.mgbean.ManagedBeanCreationException: Erreur lors de l’injection de ressources dans le bean géré «calenderController»

y-a t'il quelqu'un qui peut m'aider c'est urgent et merci d'avance 

Ci-joint le code:

ClallenderController:

@ManagedBean
@SessionScoped
public class CalenderController implements Serializable{
    private Intervention intervention;
   private  ScheduleModel eventModel;
   private List<Intervention> listIntervention;
   @ManagedProperty(value ="#{intervServ}")
   private InterventionService interventionService;

   @PostConstruct
   public void init(){
      intervention= new Intervention();
      eventModel= new DefaultScheduleModel();
        try {
            listIntervention=interventionService.findAll();
        } catch (Exception ex) {
            Logger.getLogger(CalenderController.class.getName()).log(Level.SEVERE, null, ex);
        }
        for (Intervention inter : listIntervention) {

        evt.setEndDate(inter.getDateFinint());
        evt.setStartDate(inter.getDateDebint());
