Quelqu'un saurait-il m'indiquer d'où peut venir le problème ?

Merci d'avance pour votre aide.

Tu t'es trompé d'annotation ManagedBean, ce doit être javax.faces.bean.ManagedBean (pas javax.annotation.ManagedBean)

En passant, tu devrais mettre une majuscule au nom de classe : ClientBean à la place de clientBean (c'est la norme ;))

Merci pour votre réponse.

J'ai corrigé ces erreurs mais voici ce que j'obtiens encore:
