Minha classe Person.java esta assim:

import javax.persistence.Entity;
import javax.persistence.Enumerated;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;

@Entity
public class Person {
	
	@Id
	@GeneratedValue(strategy = GenerationType.IDENTITY)
	private Long id;
	
	@Enumerated
	private String name;

	public Long getId() {

	public void setId(Long id) {
		this.id = id;
	}

	public String getName() {
		return name;
	}

	public void setName(String name) {
		this.name = name;
	}
}

O controller:

import javax.persistence.EntityManager;

import br.com.caelum.vraptor.Resource;

import com.greenlemon.chamadoweb.model.Person;
import com.greenlemon.chamadoweb.provider.EntityManagerCreator;

@Resource
public class PersonsController {

	public PersonsController(EntityManagerCreator factory){
		this.em = factory.getInstance();
	}
	
	public void form(){
	}
	
	public void create(Person person){
		em.persist(person);
	}
}

Implementei as duas classes EntityManagerFactoryCreator e EntityManagerCreator conforme esta no post VRaptor3 + GAE, parte II http://www.guj.com.br/posts/list/137866.java, e até agora não consegui resolver o problema.

Alguém tem alguma sugestão de como arrumar isso???

Lucas_Cavalcanti 17 de out. de 2009

não sei se isso vai resolver o problema, mas você pode receber direto um EntityManager. Quanto você cria um ComponentFactory, o vraptor automaticamente usa o getInstance() e injeta no construtor pra você…

você que está usando esse DataNucleus? esse projeto não tem nada a ver com o VRaptor (talvez tenha algo a ver com o GAE)

Paulo_Silveira 17 de out. de 2009

oi denis!

voce precisa fazer enhance das suas classes! o plugin do GAE faz isso automaticamente pra voce (mexe no bytecode delas). voce pode fazer manualmente, mas nao tem pra que:
http://www.datanucleus.org/products/accessplatform_1_1/guides/jpa/tutorial.html

isso nao so com vraptor, é inerente da JPA/BigTable atraves do datanucleus!

davisnog 18 de out. de 2009

Blz, comecei novamente o meu teste.

Agora esta tudo padrãozinho, implementei a classe CustomProvider como esta no site do VRaptor em componentes uteis, e o meu controller esta dessa forma:

import javax.persistence.EntityManager;

import br.com.caelum.vraptor.Resource;
import br.com.caelum.vraptor.util.jpa.EntityManagerCreator;

@Resource
public class PersonController {
	
	EntityManager em;
	
	public PersonController(EntityManagerCreator factory){
		this.em = factory.getInstance();
	}

        //tambem tentei dessa forma

	/*
         public PersonController(EntityManagerFactoryCreator factory){
		this.em = factory.getInstance().createEntityManager();
	}
       */

		
	public void create(){}
}

e agora me da a seguinte exception:

Error creating bean with name ‘personController’ defined in file [C:\Documents and Settings\Administrador\Desktop\vraptor-blank-project-gae-3.0.0\war\WEB-INF\classes\br\com\caelum\vraptor\blank\controller\PersonController.class]: Unsatisfied dependency expressed through constructor argument with index 0 of type [br.com.caelum.vraptor.util.jpa.EntityManagerCreator]: : Error creating bean with name ‘entityManagerCreator’: Unsatisfied dependency expressed through constructor argument with index 0 of type [javax.persistence.EntityManagerFactory]: : Error creating bean with name ‘br.com.caelum.vraptor.util.jpa.EntityManagerFactoryCreator’: FactoryBean threw exception on object creation; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘entityManagerFactoryCreator’: Invocation of init method failed; nested exception is javax.persistence.PersistenceException: Provider error.

Paulo_Silveira 18 de out. de 2009

Ola davis!

o erro esta ainda no datanucleus: Provider error. Provider: org.datanucleus.store.appengine.jpa.DatastorePersistenceProvider

o init dele deu algum problema, nao tem mais coisas no log? esta rodando no GAE mesmo?

davisnog 18 de out. de 2009

Sim, estou rodandando o GAE local pelo plugin do eclipse, mais o que eu postei anteriormente mais um pedaço da exception, porque é maior ainda que a primeira do post:

A exception é gigante, a exception completa esta em anexo. Tem como estar fazendo um log, configurando alguma coisa pelo lo4j pra ver o que esta acontecendo?

pmatiello 18 de out. de 2009

Davisnog, verifique se você não esqueceu de criar o persistence.xml. É uma das exigências do AppEngine. O link abaixo tem as instruções:

http://code.google.com/appengine/docs/java/datastore/usingjpa.html#Setting_Up_JPA

Boa sorte!

davisnog 18 de out. de 2009

O persistence.xml já existe sim.

pmatiello 19 de out. de 2009

O persistence.xml deve estar em war/WEB-INF/classes/META-INF/. Confere?

Não testei com esses EntityManagerFactoryCreator e EntityManagerCreator, mas consegui fazer funcionar com as seguintes classes:

@Component
@ApplicationScoped
public class EntityManagerFactoryComponentFactory implements
		ComponentFactory<EntityManagerFactory> {

	private EntityManagerFactory entityManagerFactory;

	public EntityManagerFactoryComponentFactory() {
		entityManagerFactory = Persistence
				.createEntityManagerFactory("transactions-optional");
	}

	public EntityManagerFactory getInstance() {
		return entityManagerFactory;
	}

	@PreDestroy
	public void close() {
		entityManagerFactory.close();
	}

}

@Component
@RequestScoped
public class EntityManagerComponentFactory implements
		ComponentFactory<EntityManager> {

	private final EntityManagerFactory entityManagerFactory;
	private EntityManager entityManager;

	public EntityManagerComponentFactory(
			EntityManagerFactory entityManagerFactory) {
		this.entityManagerFactory = entityManagerFactory;
	}

	public EntityManager getInstance() {
		if (this.entityManager == null) {
			this.entityManager = entityManagerFactory.createEntityManager();
		}
		return entityManager;
	}

}

Com isso eu posso receber um EntityManager diretamente no construtor dos meus controllers.

E não estou usando nenhum CustomProvider também.

Lucas_Cavalcanti 19 de out. de 2009

É isso que o matiello falou…

crie essas classes, remova o CustomProvider, e receba no construtor EntityManager direto… pra isso que servem as componentFactories, pra você poder receber o que elas fabricam no construtor das suas classes

[]'s

davisnog 19 de out. de 2009

Blz pmatiello, implementei as classes conforme você colocou, e estou recebendo em meu contrutor:

public PersonController(EntityManagerComponentFactory factory){
		this.em = factory.getInstance();
	}
//tentei tambem assim;

public PersonController(EntityManager factory){
		this.em = factory;
	}

Agora esta dando o mesmo erro que postei postei no inicio ERROR [DataNucleus.MetaData] - Found Meta-Data for class... , esse é um erro de compilação ainda.

Lucas_Cavalcanti 19 de out. de 2009

Paulo Silveira:
oi denis!

voce precisa fazer enhance das suas classes! o plugin do GAE faz isso automaticamente pra voce (mexe no bytecode delas). voce pode fazer manualmente, mas nao tem pra que:
http://www.datanucleus.org/products/accessplatform_1_1/guides/jpa/tutorial.html

isso nao so com vraptor, é inerente da JPA/BigTable atraves do datanucleus!

abracos

Você já fez isso que o Paulo falou?

davisnog 19 de out. de 2009

A proposito, como faço pra renomear um projeto no eclipse?
Por exemplo de vraptor-gae para myappteste, eu renomeio todas as referencias onde tem vraptor-gae para myappteste e quando eu mando rodar a aplicação sempre da HTTP Status 404, isso esta acontecendo tanto no Tomcat quanto eu tento renomear o exemplo vraptor-blank, quanto o vraptor-gae no GAE.

Lucas_Cavalcanti 19 de out. de 2009

Botão direito no projeto >> properties >> Web-project Settings

muda pro contexto que vc quiser

davisnog 19 de out. de 2009

lucascs, como eu to usando o plugin do eclipse ele já mexe nos byte codes, quanto ao tutorial do jpa, eu não consegui ver ainda aonde esta o erro pois a classe somente tem duas propriedades, id e name.

Lucas_Cavalcanti 19 de out. de 2009

O problema que está dando é do datanucleus…

ele tenta chamar o init, e tá dando uma PersistenceException…

tenta ver qual é a mensagem dessa PersistenceException…

Será que o nome da persistence-unit não está errado?

davisnog 19 de out. de 2009

lucascs pelo que eu vi esta correto o persistence-unit, achei esse link aqui http://groups.google.com/group/google-appengine-java/browse_thread/thread/16e3076527b7f48c/1af072dd5156556c?lnk=raot&pli=1 mais também não diz muita coisa.

Pra falar a verdade já perdi muito tempo com isso, vou fazer o basicão mesmo e usar o Tomcat.

Se alguem tiver um CRUD ai funcionando VRaptor + GAE e puder me mandar já fico satisfeito, pois agora tenho que correr atraz do tempo perdido, esse projeto da Faculdade já esta atrasado e não posso mais perder tempo. Fica pra uma próxima.

Valeu.

davisnog 20 de out. de 2009

lucascs sobre renomear o projeto eu fiz o que vc falou e show de bola funciona, mais quando eu renomeio os packages e o web.xml dai para de funcionar HTTP Status 404, tem que fazer algo a mais??? No caso eu quero renomear o projeto todo.

davisnog 20 de out. de 2009

Opss, quanto ao erro 404 eu já consegui achar o erro, a classe CustomProvider não estava compilando, por acaso fui em java build path e vi que a biblioteca JRE estava vermelhinho(faltando alguma coisa) dai fui ver que não tinha nada nenhum .jar na biblioteca, editei a biblioteca e setei workspace default jre, e dai tudo funcionou.

Vamos de tomcat por enquanto, huhuhu.

public class EntityManagerFactoryComponentFactory implements
		ComponentFactory<EntityManagerFactory> {

	private EntityManagerFactory entityManagerFactory;

	public EntityManagerFactoryComponentFactory() {
		entityManagerFactory = Persistence
				.createEntityManagerFactory("transactions-optional");
	}

	public EntityManagerFactory getInstance() {
		return entityManagerFactory;
	}

	@PreDestroy
	public void close() {
		entityManagerFactory.close();
	}

}

@Component
@RequestScoped
public class EntityManagerComponentFactory implements
		ComponentFactory<EntityManager> {

	private final EntityManagerFactory entityManagerFactory;
	private EntityManager entityManager;

	public EntityManagerComponentFactory(
			EntityManagerFactory entityManagerFactory) {
		this.entityManagerFactory = entityManagerFactory;
	}

	public EntityManager getInstance() {
		if (this.entityManager == null) {
			this.entityManager = entityManagerFactory.createEntityManager();
		}
		return entityManager;
	}

}

Com isso eu posso receber um EntityManager diretamente no construtor dos meus controllers.

E não estou usando nenhum CustomProvider também.

Você colocou essas classes acima no seu projeto? (copy e paste mesmo)
com essas classes no projeto (em baixo do pacote básico configurado no web.xml) deve funcionar...

Sim, já adicionei essas classes sim.
Não sei o que fazer, por enquanto vou deixar assim mesmo, numa proxima vez eu tento novamente.

Valeu mesmo pela ajuda.

Voce precisar executar o DataNucleus Enhancer. Se voce esta usando o plugin do google, o enhancer é executado automaticamente. Neste caso, se o enhancer esta sendo executado, entao voce precisa ver os logs do enhancer pois deve ter algum erro na declaracao do metadata de suas classes.
