Já tentei várias maneiras e não consigo persistir a classe PaisEntity.

Agora que você está utilizando o Wildfly, pode alterar teu dao para algo assim:

@Stateless
public class PaisRepository implements Serializable {
    @PersistenceContext
    private EntityManager em;
    //Restante do código
    
    public List<PaisEntity> listaTodosPaises() {
        StringBuilder hqlSelect = new StringBuilder(hql);
        final String query = "SELECT" + hqlSelect;
        Query querySelect = em.createQuery(query);
        List<PaisEntity> resultList = querySelect.getResultList();
        return resultList;
    }
    //Demais código aqui
}

Veja se funciona.

Luis_Augusto_Santos · Março 23, 2017, 7:52pm

Um ponto de atenção é que, quando você utiliza EJBs, precisará fazer a injeção dos mesmos.
Acontece que, por regras da especificação, um EJB só pode ser injetado em:

Outro ejb
Uma servlet
Um managed bean
Assim sendo, se você possui um controller, pode injetar teu DAO assim:

@Stateless
public class PaisController {
@EJB
private PaisDao paisDao;
//Resto do código aqui
}

E, no managed bean

@ManagedBean(name = "seuBean")
public class ManagedBean {
    @EJB
    private PaisController paisController;
    //Demais código aqui
}

Assim você fecha o ciclo de injeções e quando o seu módulo for “deployado” pelo wildfly, as instâncias necessárias estarão aptas para injeção (elas serão injetadas quando necessárias).

@guilhermebhte, tudo isso que te falei se encaixa na questão dos conceitos das diversas especificações que se enquadram na especificação JEE.
Eu, particularmente, tenho uma relação de amor e ódio com JEE, pois acho fantástico tudo o que ele permite, ao mesmo tempo que acho terrível que um padrão seja tão complexo.
Eu não sou muito fã do Spring, mas, tenho que concordar que em diversos aspectos, ele é muito mais simples e intuitivo que o JEE.
Se você tiver oportunidade (e interesse) em estudar Spring Boot + Spring Data, verá o quão simples é fazer tudo isso que você fez.
Sem contar que você nem entrou nos méritos de utilizar o CriteriaBuilder do JPA, que é extremamente confuso e complexo, ao meu ver.

Estou fazendo cursos sobre estas matérias, pois estou precisando mesmo.

É porque achei que tanto o Spring e JSF, por utilizar algo em comum, a saída era a mesma.

Valeu
