Binding não funciona!

[Luciano_Khrisley]

preciso de ajuda!!!
Estou desenvolvendo um projeto WEB usando NetBeans, servidor TomCat, API JPA com Hibernate, estou tendo o seguinte problema ao rodar a aplicação:
o objetivo é gravar um conta no banco de dados “MySql”.

HTTP Status 500 -

note The full stack trace of the root cause is available in the Apache Tomcat/6.0.26 logs.
Apache Tomcat/6.0.26

isso acontece assim que clico no commandButton Gravar do meu XHTML, que faz o Binding com o meu ManagedBean, que também vou deixar aqui para ser observado:

public void grava() {
EntityManager em = new JPAUtil().getEntityManager();
em.getTransaction().begin();

ContaDAO dao = new ContaDAO(em);

dao.adiciona(conta);

this.contas = dao.lista();

em.getTransaction().commit();
em.close();

limpaFormularioDoJSF();
}

de acordo com configurações usadas em outros projetos, minha JPAUtil esta correta e de arcodo com minha unidade de persistencia.
por favor, me ajudem!!!
grande abraço.

[davidbuzatto]

Oi Luciano, primeiramente recomendo essa leitura aqui: http://www.guj.com.br/posts/list/50115.java
Por favor, dê uma olhada ok?

Quanto ao seu problema, acho que o stacktrace da excessão esteja incompleto.
Parece ser um problema na persistencia da sua conta, não um problema no binding.
Teria como vc pegar o stacktrace completo no log do tomcat? Ou então tratar a excessão onde você fazer a persistência e mandar dar um print no stacktrace?

[FernandoCartaxo]

Como está o mapeamento da sua entidade?

[Luciano_Khrisley]

Seria esse o mapeamento Fernando?

me desculpe mas sou novo no assunto.

[b]import javax.persistence.EntityManager;
import javax.persistence.EntityManagerFactory;
import javax.persistence.Persistence;

public class JPAUtil {

private static EntityManagerFactory entityManagerFactory;

static {
	entityManagerFactory = Persistence.createEntityManagerFactory("nome da unidade de persistencia");
}

public EntityManager getEntityManager() {
	return entityManagerFactory.createEntityManager();
}

}[/b]

grande abraço.

espero q esteja mais facil de entender…

preciso muito da ajuda…

grande abraço.

[davidbuzatto]

Você leu o tópico que passei? Se tivesse lido, estaria mais fácil de entender sim.

Seu problema é que não está sendo encontrada a unidade de persistência.
No Persistence provider for EntityManager named controlefinancas

Espero que isso aquientityManagerFactory = Persistence.createEntityManagerFactory("nome da unidade de persistencia"); Você só tenha postado para mostrar como está fazendo, pq vc tem que informar o nome da unidade de persistência na factory.

Verifique se a unidade que você está informando (controlefinancas) está definida no persistence.xml

[]´s

[Luciano_Khrisley]

sim… só coloquei como exemplo… o nome esta controlefinancas.

estou aprendendo a usar o fórum, desculpe…

continuo com o problema…

abraços

[thwess]

Desculpe desenterrar esse tópico, mas é que estou com o mesmo problema do nosso colega acima, porém não sei se ele resolveu o problema, enfim, o que tudo indica é que o problema seja mesmo esse com a unidade de persistência, porém eu conferi diversas vezes e esta tudo correto, gostaria que alguém me desse uma luz.

Vou postar meus códigos.

}[/code]

Já debuggei diversas vezes e essa linha é a responsavel pelo problema.

EntityManager em = new JPAUtil().getEntityManager();

[thwess]

Que estranho, fiz uma classe para testar o hibernate e essas classes que eu suspeitava estarem causando problemas, no entando o teste passou.

Como resultado, agora não sei mais o que pode estar dando errado, pois o persistence.xml e a JPAUtil.java estão bem configurados e a linha EntityManager em = new JPAUtil().getEntityManager(); esta funcionando numa boa.
