Dúvida no Ex. 9 da Aula 2 - Configuração e inicialização do JPA

Oi Renato,

provável que falte uma dependência no pom.xml.

vc adicionou o hibernate-entitymanager?

http://mvnrepository.com/artifact/org.hibernate/hibernate-entitymanager

Olá Nico,

Eu fiz o que voce me disse para fazer e agora dá esse erro

Exception in thread "main" java.lang.NoClassDefFoundError: org/hibernate/internal/util/xml/XsdException at org.hibernate.jpa.HibernatePersistenceProvider.getEntityManagerFactoryBuilderOrNull(HibernatePersistenceProvider.java:80) at org.hibernate.jpa.HibernatePersistenceProvider.getEntityManagerFactoryBuilderOrNull(HibernatePersistenceProvider.java:71) at org.hibernate.jpa.HibernatePersistenceProvider.createEntityManagerFactory(HibernatePersistenceProvider.java:52) at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:55) at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:39) at br.com.paulistano.util.JPAUtil.(JPAUtil.java:10) at br.com.paulistano.dao.CsvDao.buscaPeloIdConta(CsvDao.java:38) at br.com.paulistano.dao.CsvDao.inserirDados(CsvDao.java:18) at br.com.paulistano.principal.TesteJPA.main(TesteJPA.java:17) Caused by: java.lang.ClassNotFoundException: org.hibernate.internal.util.xml.XsdException at java.net.URLClassLoader$1.run(URLClassLoader.java:366) at java.net.URLClassLoader$1.run(URLClassLoader.java:355) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:354) at java.lang.ClassLoader.loadClass(ClassLoader.java:425) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:308) at java.lang.ClassLoader.loadClass(ClassLoader.java:358) ... 9 more

Oi Renato, coloque aqui que o seu pom.xml!

Use ``` para formatar e facilitar a leitura.

E essa é a minha classe JpaUtil, onde ao executar o createEntityManagerFactory("bcotst-unit"), ele acusa erro

package br.com.paulistano.util;

import javax.persistence.EntityManager;
import javax.persistence.EntityManagerFactory;
import javax.persistence.Persistence;

public class JPAUtil {

    private static EntityManagerFactory entityManagerFactory = Persistence
            .createEntityManagerFactory("bcotst-unit");

    public EntityManager getEntityManager() {
        return entityManagerFactory.createEntityManager();
    }

}

Meu persistence.xml

Oi Renato,

usa a mesma versão do hibernate nas dependencias hibernate-entitymanager e hibernate-core: 5.0.5.Final

E bem vindo ao famoso JAR HELL do mundo java :)

abs

Oi Renato, funcionou? Ou ainda JAR-HELL? \o/

abs

Olá Nico,

Desculpa não ter te respondido de imediato, problemas com o sinal da internet.

Então funcionou sim, porém ao invés de usar a versão 5.0.5, utilizei a 4.3.10, a versão 5.05 ainda dava o mesmo problema.

Mas, fora isso funcionou sim, obrigado !

Otimo Renato! Podemos fechar essa pergunta então?

E provavel que falte mais uma dependência quando usa a versão 5 do hibernate.

Abs, Nico
