Fórum EntityManager JPA2 e Session Hibernate juntos #419940

Java

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
view plaincopy to clipboardprint?

    @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 na minha aplicação
    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.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

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

E não terá problemas, já se fechará as conexões e não se preocupa pois o hibernate implementa a especificação do jpa2.

eu ja havia tentando desse jeito tbm
e o erro é o msm

Eu uso datasource configurando no glassfish 3.1.2

e estou usando inject @PersistenceContext(unitName=UNIT_NAME), no EntityManager
ao tentar cada um o erro é o msm

Session session = em.unwrap(Session.class);


ou 
Session session = (Session) em.getDelegate();


Erro:

pesquisando por ai
eu vi que alguns
delaclara o Session dentro do metodo aonde vai usa-lo
fazendo isso ele não deu problema
ao acessar qualquer página

mas ainda não testei nenhuma criteria

esse é o jeito correto(Dentro do metodo declarar o Session)

to mudando aqui
@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;
	}


agora nao preciso fica declarando ela local
vou fazer os teste

vlw por enquanto

Thiago Volpato


valeu pelos links

resolvi dessa maneira

Session session = (Session)((EntityManagerImpl)getEm().getDelegate()).getDelegate();

criando um em cada metodo que possui um session do hibernate

agora vou tentar implementar de uma maneira mais eficiente

Obrigado
