Bom dia,

Resolvi começar a estudar sobre o VRaptor, vi muita gente falando bem dele.

Então, ja pesquisei bastante na net, e aqui no forum tb, estou com 1 problema, nao to conseguindo fazer o deploy da minha aplicacao, esta dando erro, segue abaixo o erro e os arquivos:

E onde crio o entityManagerFactory

JPAFactory

public class JPAFactory {

	private static EntityManagerFactory factory;
	
	public JPAFactory() {}
	
	public static EntityManager getEntityManager() {
		if (factory == null) {
			factory = Persistence.createEntityManagerFactory("vraptor");
		}
		return factory.createEntityManager();
	}
	
}

Detalhe, os arquivos orm.xml e persistence.xml estao na pasta src/META-INF, so fiz criar nela esses arquivos.

Ja agradeço pela ajuda =D

#2

Esqueci de falar, uso o JBoss 7.0

#3

troque no persistence.xml:

<persistence-unit name="vraptor">

por

<persistence-unit name="default">

o componente padrão do vraptor procura com esse nome.

#4

Opa lucas, de antemao agradeço sua ajuda.

Sobre a troca daquele nome para default, eu fiz isso mas mostra a mesma mensagem de erro. Troquei tb no meu JPAFactory e tb continua o mesmo erro.

Nao sei se ta muito certo, mas ai vai meu web.xml, pode ser que tenha errado alguma coisa sem conhecer. E outra coisa, no web.xml eu declaro como provider a classe da JPa, e no persistence, o do Hibernate, nao sei se tem algo a ver.

a sua pasta src é uma source folder? META-INF tá escrito certo? persistence.xml tá escrito certo?

#6

Vo postar a imagem do meu workspace, eu peguei um tutorial da net, e ate baixei a fonte do cara que criou o tutorial, e ate as libs, mas rola Naaaaadaaaa…heheheheh

segue o link da imagem: http://i902.photobucket.com/albums/ac222/rof20004/workspace_zps1a240156.png

vlw

up, sem bronca =D

#8

troque o

<context-param>    
    <param-name>br.com.caelum.vraptor.provider</param-name>    
    <param-value>br.com.caelum.vraptor.util.jpa.JPACustomProvider</param-value>    
  </context-param>

por

<context-param>    
    <param-name>br.com.caelum.vraptor.packages</param-name>    
    <param-value>br.com.caelum.vraptor.util.jpa</param-value>    
  </context-param>

e você trocou o nome do persistence-unit?

#9

Sim lucas troquei o nome do persistence-unit para default, vou fazer o teste dessa mudanca que voce me falou agora mesmo, um minuto ‘-’

#10

Deu certo nao, resolvi tirar todo o context e deu o deploy certinho, que estranho, mas agora aparece outro erro, quando vou carregar a pagina, vo postar aqui:

     }
 
}
#11

Errei, é esse o erro:

#12

deve ter alguma outra coisa na stacktrace… algum caused-by que explique o problema…

o que vc quis dizer com tirar todo o context?

#13

Lucasssss

Uhu mano, consegui!!!

O problema é que faltava um construtor VAZIO no GenericDAO, agora o porque eu nao sei, tive que fazer uma gambiarra mesmo, adicionando 2 construtores, 1 vazio e o outro com uma assinatura que nao é utilizada, da uma olhada ae:

package br.com.k2studio.vraptor.dao;
 
import java.util.List;

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

import br.com.caelum.vraptor.ioc.Component;
import br.com.k2studio.vraptor.jpa.BaseEntity;
import br.com.k2studio.vraptor.jpa.JPAFactory;

@Component
public class GenericDAO {
 
     private EntityManager manager;
 
     public GenericDAO() {}
     
     public GenericDAO(EntityManager manager) {
          this.manager = JPAFactory.getEntityManager();
     }


  // Resto do codigo
#14

Ahhh, obrigado pela ajuda, eu realmente nao sabia que o VRaptor usava default no persistence-unit.
