[Resolvido] EntityManager JPA2 e Session Hibernate juntos

tmvolpato 15 de julho de 2012

Boa tarde,

Atualmente estou usando o entityManager (JPA2), na minha aplicação
mas surgiu a necessidade de usar criteria do hibernate
eu sei que o JPA possui mas não é lá aquelas coisas

então resolvi que para criteria iri usar o hibernate, até ai tudo bem

Pesquisando achei que para obter o session preciso fazer isso

@PersistenceContext(unitName=UNIT_NAME)
	private EntityManager em;
 
Session session = em.unwrap(Session.class);

eu nem cheguei a usar o session e deu o seguinte erro ao acessar uma lista

Caused by: javax.ejb.EJBException: javax.ejb.CreateException: Could not create stateless EJB
	at com.sun.ejb.containers.StatelessSessionContainer$SessionContextFactory.create(StatelessSessionContainer.java:726)
	at com.sun.ejb.containers.util.pool.NonBlockingPool.getObject(NonBlockingPool.java:247)
	at com.sun.ejb.containers.StatelessSessionContainer._getContext(StatelessSessionContainer.java:449)

	at com.sun.ejb.containers.StatelessSessionContainer.createStatelessEJB(StatelessSessionContainer.java:475)

Está faltando mais alguma coisa para que eu possa usar o EntityManager e o Session do hibernate juntos

Obrigado desde já

ve o construtor dessa classe DepartmentDAOImpl tem algum problema nela

tmvolpato 15 de jul. de 2012

eu estava usando apenas o entityManager funciona normal

na Classe DepartmentDAOImpl nao possui construtor
e nessa classe estou usando apenas o entityManager

o problema deu qdo o fui tenta obter o Session Hibernate

e pelo que eu estou percebendo depois disso eu não tenho mais o meu entityManager

Para implementar o session do hibernate só preciso fazer isso:

@PersistenceContext(unitName=UNIT_NAME)  
    private EntityManager em;  
  
Session session = em.unwrap(Session.class); (Só isso)

eu fiz um teste e realmente depois disso eu tenho um session, mas prejudicou o que estava funcionando

lsjunior 15 de jul. de 2012

No entity manager tem o metodo getdelegate, que retorno o session quando se esta usando o hibernate como provedor.

tmvolpato 15 de jul. de 2012

eu vi isso

mas eu procurei e fala que pra quem usa JPA2

é só fazer isso

ai que esta minha duvida, pq só isso não funcionou 100%

mas eu procurei e fala que pra quem usa JPA2

é só fazer isso

ai que esta minha duvida, pq só isso não funcionou 100%

Eu uso da seguinte forma:

Session session = (Session) entitymanager.getDelegate();

session.createCriteria() ......

tmvolpato 15 de jul. de 2012

dessa maneira vc trabalha com os dois?

eu falo assim, para salvar, remover e atualizar usar o EntityManager
e só para pesquisa usar o session do hibernate

só isso, vc abre e fecha a conexao do hibernate?
ou nao precisa?

tmvolpato 16 de jul. de 2012

Pesquisando por ai

eu li que o @PersistenceContext(unitName=UNIT_NAME)
não funciona com EJB 3.1

estranho que até o momento estava normal ,
foi só tenta usar Session do hibernate deu problema

fazendo assim;

@PersistenceContext(unitName=UNIT_NAME) private EntityManager em;

ou assim

Erro:

maior_abandonado 16 de jul. de 2012

o que tem nessas duas linhas:

DepartmentServiceImpl.java:33
DepartmentDAOImpl.java:35

aliás poste ambos, ao menos o método completo de cada uma dessas linhas/classes

tmvolpato 16 de jul. de 2012

na verdade era sujeira aquilo

Deixei assim :

@PersistenceContext(unitName=UNIT_NAME)
	private EntityManager em;
	
	public EntityManager getEm() {
		return em;
	}
		
	private Session session;
	
	public Session getSession() {
		if (em != null){
			session = (Session) getEm().getDelegate();
		}
		
		return session;
	}

segue o novo erro

criei uma lista simples com criteria
e deu esse erro

Resolvido

segue abaixo como eu resolvi

@PersistenceContext(unitName=UNIT_NAME)
	private EntityManager em;
	
	public EntityManager getEm() {
		return em;
	}
	
	private Session session;
	
	public Session getSession(){
		if (em != null){
			
			this.session = (Session)((EntityManagerImpl)getEm().getDelegate()).getDelegate();
	   }
		return session;
	}

Agora é só pegar o getSession
