Muitas vezes, a stack do erro nos diz o que aconteceCaused by: java.lang.ClassCastException: br.com.netsoft.desif.model.endereco.PaisEntity cannot be cast to java.util.List te diz algo? Em PaisController…
guilhermebhte 21 de mar. de 2017
Está dizendo que não pode ser uma lista.
Foi corrigido.
Mas deu outro erro:
A linha 40 está assim:
ArrayList paises = (ArrayList) paisDao.listarPaises();

Significa que você está tentando realizar o cast em um objeto que está nulo.

Luis_Augusto_Santos 21 de mar. de 2017
Desculpe, agora que postou o código inteiro é que vi.private PaisDao paisDao; e a chamada a um método dele aqui List<PaisEntity> paisesBusca = paisDao.listarPaises();
guilhermebhte 21 de mar. de 2017
Nesta parte do código que você citou.
Luis_Augusto_Santos 21 de mar. de 2017
Quando mudou?new para criar um novo objeto ou você usa anotação de injeção ou você mapeia isso num xml para injeção também.private PaisDao paisDao;, para mim (e para o compilador e para a JVM) é só a declaração.
guilhermebhte 21 de mar. de 2017
Entendo, posso estar errado, mas o retorno desta função é uma lista de PaisEntity, por isto disse.
Mas pode me dar um exemplo de como ajustar ?
Luis_Augusto_Santos 21 de mar. de 2017
Não estou mais me referindo ao retorno do método listarPaises. Eu me refiro ao fato de você só ter declarado o PaisDao e não tê-lo instanciado.private String nome; public void teste() { System.out.println(nome.toUpperCase()); }paisDao = new PaisDao(); em algum lugar do teu código, antes de invocar isso @SuppressWarnings("unused") List<PaisEntity> paisesBusca = paisDao.listarPaises();
guilhermebhte 21 de mar. de 2017
Assim ?
@PostConstruct
public void init () {
System . out . println ( "Página inicial de países." );
paisDao = new PaisDao ();
@SuppressWarnings ( "unused" )
List < PaisEntity > paisesBusca = paisDao . listarPaises ();
Luis_Augusto_Santos 21 de mar. de 2017
Exato. Isso deve resolver o NullPointerException
guilhermebhte 21 de mar. de 2017
Agora deu erro no hql, nesta linha:
Query querySelect = em . createQuery ( query );
Acho eu que é a mesma coisa.
package br.com.netsoft.desif.dao.endereco ;
import java.io.Serializable ;
import java.util.List ;
import javax.persistence.EntityManager ;
import javax.persistence.Query ;
import br.com.netsoft.desif.model.endereco.PaisEntity ;
public class PaisDao implements Serializable {
private static final long serialVersionUID = 1402488530698938353L ;
final private String hql = " p FROM PaisEntity p " ;
EntityManager em ;
public List < PaisEntity > listarPaises () {
StringBuilder hqlSelect = new StringBuilder ( hql );
final String query = "SELECT " + hqlSelect ;
Query querySelect = em . createQuery ( query );
@SuppressWarnings ( "unchecked" )
List < PaisEntity > resultList = querySelect . getResultList ();
return resultList ;
}
}
Luis_Augusto_Santos 21 de mar. de 2017
Mesma situação da anterior. Onde você instancia o EntityManager?
guilhermebhte 21 de mar. de 2017
Pesquisei, fiz alguns testes mas o erro continua.
Meu persistes esta correto ?

Luis_Augusto_Santos 21 de mar. de 2017
Se o persistence.xml está ok, não sei e nem vou verificar.@PersistenceContext
guilhermebhte 21 de mar. de 2017
Isto eu já tinha feito @Luiz_Augusto_Prado
@PersistenceContext EntityManager em;
Coloquei o arquivo persistence.xml, pois achei que o erro poderia estar lá
Luis_Augusto_Santos 21 de mar. de 2017
O erro persiste? Qual a mensagem? Pode ser mais claro quando colocar alguma informação?
guilhermebhte 21 de mar. de 2017
@Luis_Augusto_Santos , fazendo o debug, o sistema vai até a linha, Query querySelect = em.createQuery(query) ;
Com a anotação ou não entendo que o erro é o mesmo.

Luis_Augusto_Santos 21 de mar. de 2017
Uma coisa que você precisa fazer, com urgência, é aprender a ler o erro.PaisDao.java:27?
guilhermebhte 21 de mar. de 2017
Entendi que o erro está aqui e que está nulo.
Mas ao fazer o debug, ai fiquei confuso.
Luis_Augusto_Santos 21 de mar. de 2017
O objeto em, do EntityManager está nulo.
guilhermebhte 21 de mar. de 2017
Isto eu entendi.
Eu não estou conseguindo é instanciar este objeto no jsf.
Em um projeto no Spring, com o mesmo banco de dados, funcionou e com jsf não.
É um projeto web.
Estou utilizando maven, hibernate, jpa,jsf, primefaces, postgres.
No Spring, ele instancia só de ter isto
@PersistenceContext
EntityManager em ;
Neste do JSF não, realmente está nulo.
Luis_Augusto_Santos 21 de mar. de 2017
Está rodando este projeto onde? Tomcat? Glassfish? Wildfly?
guilhermebhte 21 de mar. de 2017
Luis_Augusto_Santos 21 de mar. de 2017
Como está teu pom.xml?
guilhermebhte 21 de mar. de 2017
Correto.
Eu queria configurar o jboss, mas também é outro passo.

Mais algo que posso fazer ?
guilhermebhte 21 de mar. de 2017
Fiz estas alterações e mudou o erro.
Acho que a classe não está persistindo, conforme descrição do log:

Cara, quantas vezes terei que dizer que o problema está no EntityManager que não foi injetado?long serialVersionUID = 1402488530698938353L;
final private String hql = " p FROM PaisEntity p " ;
EntityManager em ; `
Onde está a anotação?
guilhermebhte 22 de mar. de 2017
@Luis_Augusto_Santos , nesta mensagem eu informei que fiz e não adiantou.
Isto eu entendi.
Eu não estou conseguindo é instanciar este objeto no jsf.
Em um projeto no Spring, com o mesmo banco de dados, funcionou e com jsf não.
É um projeto web.
Estou utilizando maven, hibernate, jpa,jsf, primefaces, postgres.
No Spring, ele instancia só de ter isto
@PersistenceContext
Neste do JSF não, realmente está nulo.
Luis_Augusto_Santos 22 de mar. de 2017
E só por que não adiantou você removeu?
guilhermebhte 22 de mar. de 2017
Estava tentando de outra forma @Luis_Augusto_Santos .
Ou isto está errado ?
StringBuilder hqlSelect = new StringBuilder ( hql );
final String query = "SELECT" + hqlSelect ;
EntityManagerFactory factory = Persistence . createEntityManagerFactory ( "PaisEntity" );
EntityManager manager = factory . createEntityManager ();
Query querySelect = manager . createQuery ( query );
@SuppressWarnings ( "unchecked" )
List < PaisEntity > resultList = querySelect . getResultList ();
return resultList ;
guilhermebhte 22 de mar. de 2017
Vou voltar com a anotação
guilhermebhte 22 de mar. de 2017
Voltei ao DAO que estava antes:
package br.com.netsoft.desif.dao.endereco ;
import java.io.Serializable ;
import java.util.List ;
import javax.persistence.EntityManager ;
import javax.persistence.PersistenceContext ;
import javax.persistence.Query ;
import br.com.netsoft.desif.model.endereco.PaisEntity ;
public class PaisDao implements Serializable {
private static final long serialVersionUID = 1402488530698938353L ;
final private String hql = " p FROM PaisEntity p " ;
@PersistenceContext
EntityManager em ;
public List < PaisEntity > listarPaises () {
StringBuilder hqlSelect = new StringBuilder ( hql );
final String query = "SELECT " + hqlSelect ;
Query querySelect = em . createQuery ( query );
@SuppressWarnings ( "unchecked" )
List < PaisEntity > resultList = querySelect . getResultList ();
return resultList ;
}
}
O erro é:

Eu acho que o sistema não está persistindo as classes do persistence.xml

Voce esta tentando injetar uma dependencia que é container-managed sem estar em um container, coloque a anotação @Stateless na sua classe
http://docs.oracle.com/javaee/7/api/javax/persistence/PersistenceContext.html
Luis_Augusto_Santos 22 de mar. de 2017
@matrella2 , para isso ele precisará incluir artefatos no pom.xml
matrella2 22 de mar. de 2017
Achei que ele estava em um servidor de aplicação, parece que no controller ele não instanciou o paisDao, não sei se pretende utilizar injeção de dependencias, mas se for o caso e estiver usando o weld, teria que remover a anotação managed bean do JSF e utilizar a Named para o weld reconhecer alem de implementar o serializable.
Luis_Augusto_Santos 22 de mar. de 2017
Na verdade, ele está utilizando tomcat 8 (logo, não é um application server).

@Luis_Augusto_Santos E @matrella2 , sei que este post está grande, mas o que teria que fazer para consegui rodar esta aplicação.
Tenho o JBOSS EAP 7, mas da erro 404 quando incluo o sistema nele.
Desculpe incomodar, e obrigado pela ajuda.
Posso baixar e instalar qualquer servidor que acharem necessário.
Luis_Augusto_Santos 22 de mar. de 2017
Duas perguntas: por que precisa ser o jboss eap 7? Por que não pode ser um wildfly 8?
guilhermebhte 22 de mar. de 2017
Posso utilizar wildfly 8. Desde que a aplicação sobe.
Falei sobre o jboss 7, porque que sempre conheci o jboss e não conhecia o wildfly.
Luis_Augusto_Santos 22 de mar. de 2017
Então baixa o wildfly, descompacta ele.
Vai até standalone e renomeia o arquivo standalone.xml para standalone-old.xml
Então, entra em bin.
Após isso, executa o standalone.bat, ele irá iniciar o servidor.
