Bonjour
j'ai créer deux methode
/** <code>select o from Address o where o.addrid like :id</code> */
public Address getAddressFindById(String id) {
return (Address)em.createNamedQuery("Address.findById").setParameter("id", id).getSingleResult();
}

/** <code>select o from Address o where o.addrid like :id</code> */
@WebMethod(exclude = true)
public List<Address> getAddressFindById(Object id) {
return em.createNamedQuery("Address.findById").setParameter("id", id).getResultList();
}
et namedquery
@NamedQueries({

@NamedQuery(name = "Address.findById", query = "select o from Address o where o.addrid like :id")
})
apres le lancement du service web, en rentrant le id (string) a 25 comme il est rempli dans la table address j'obtiens cette erreur :
<EndpointMethodHandler><invoke> null
