java ee, glassfish et mysql

Bonjour chers développeurs.
Je commence à peine à coder et voilà ce que j'ai:
Je suis en train de concevoir une application web avec java.
J'utilise jdk 8u91, netbeans 8.0.2 et mysql 5.6.31.

Voici les différents codes:

public class ClientBean {
    @PersistenceContext(unitName = "ProjetSout-ejbPU")
    private EntityManager em;
 
    public Client creerClient(Client clt){
        em.persist(clt);
        return clt;
    }
 
    public List<Client> getAllClients() {  
        Query query = em.createNamedQuery("Client.findAll");  
        return query.getResultList();  
    } 
 
 
    public void persist(Object object) {
        em.persist(object);
    }
 
 
    // Add business logic below. (Right-click in editor and choose
    // "Insert Code > Add Business Method")
}

Après le déploiement et l'exécution de l'application je reçois ceci:
