[RESOLVIDO] vRaptor - Caused by: java.lang.IllegalStateException: EntityManager is closed

Assuntos Gerais
#1

Eu achei ter resolvido esse problema, mas está acontecendo algo muito estranho…
A EntityManager fica ocilando, as vezes ele faz as query’s, as vezes da esse erro

Caused by: java.lang.IllegalStateException: EntityManager is closed

SOLUÇÃO:

O que estava ocorrendo era que eu tinha uma anotação de @SessionScope e um EM na mesma classe, segundo Lucas Cavalcanti (quem me auxiliou na resolução do problema), eu estava abrindo uma session e dps usava um EM que é um escope de request. Ou seja, na 2a requisição ele estava guardando o EM da requisição anterior.

Mudei minha anotação @SessionScope para minha classe Usuario e está resolvido! :smiley:

Agradecimentos, Lucas Cavalcanti

#2

qual classe vc tá usando pra abrir o EntityManager?

#3

Estou usando JPA, não sei ao certo se eu tenho esse controle de abrir e fechar a EntityManager, mas a classe que aparentemente mexe com isso é a GenericBusiness.

[code]package br.com.business.common;

import java.lang.reflect.ParameterizedType;
import java.util.Collection;

import javax.persistence.EntityManager;
import javax.persistence.Query;

import br.com.caelum.vraptor.ioc.Component;
import br.com.business.GenericRepository;
import br.com.model.common.AbstractEntity;

@Component
public abstract class GenericBusiness implements GenericRepository {

protected final EntityManager manager;
private final Class<T> clazz;

protected GenericBusiness(EntityManager manager) {
	this.manager = manager;

	@SuppressWarnings("unchecked")
	Class<T> clazz = (Class<T>) ((ParameterizedType) getClass().getGenericSuperclass()).getActualTypeArguments()[0];

	this.clazz = clazz;
}

public Collection<T> all() {
	Query query = manager.createQuery("from " + clazz.getName());

	@SuppressWarnings("unchecked")
	Collection<T> list = query.getResultList();

	return list;
}

public T getById(int id) {
	return manager.find(clazz, id);
}

public void remove(T entity) {
	//manager.remove(manager.getReference(clazz, entity.getId()));
}

public T save(T entity){
	return manager.merge(entity);
}

public T merge(T entity){
	return manager.merge(entity);
}

}[/code]

vc tem o pacote do VRaptor jpa registrado no web.xml? tem alguma componentFactory de EntityManager no sistema?

#7

quem controla o open/close do EntityManager não é a JPA… ela só é a especificação…

quando vc roda dentro de um servidor de aplicação, ele mesmo se encarrega de abrir e fechar o entityManager, mas não é o caso da sua aplicação…

como vc registrou o pacote da jpa do VRaptor, ele é quem abre e fecha o EM. O erro sugere que tem algum EM sendo usado após o seu fechamento…

O problema está aqui:

@SessionScoped  
@Component  
public class UsuarioBusiness extends GenericBusiness<Usuario>{

esse cara é sessionScoped, mas recebe um entityManager que é escopo de request. Ou seja, na 2a requisição ele vai estar guardando o EM da requisição anterior…

algum motivo pra esse cara ser @SessionScoped? se não, remova essa anotação.

@Component  
public class UsuarioBusiness extends GenericBusiness<Usuario>{

esse cara é sessionScoped, mas recebe um entityManager que é escopo de request. Ou seja, na 2a requisição ele vai estar guardando o EM da requisição anterior…

algum motivo pra esse cara ser @SessionScoped? se não, remova essa anotação.[/quote]

O pior que eu preciso desse @SessionScope, pq preciso pegar os dados do usuario para verificar se ele esta logado, etc…

Existe alguma outra solução para esse meu caso ?

Por exemplo, daria algum problema eu usar esse @SessionScope no Usuario ?

O UsuarioBusiness não precisa ser @SessionScope, já que ele não guarda o Usuário…

crie uma classe diferente, @SessionScope, que guarda o usuario retornado pelo método autenticar do business… daí o business pode ficar como request scoped (o default)
