this is my persistence file

<?xml version="1.0" encoding="UTF-8"?>

	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

		</properties>
	</persistence-unit>

</persistence>

this is the class that I excute.

package caelum.virtual.gwt.server;

import javax.persistence.EntityManager;
import javax.persistence.EntityManagerFactory;
import javax.persistence.Persistence;

import caelum.virtual.gwt.client.Editora;

public class GeraTabelas {

	public static void main(String[] args) {
		EntityManagerFactory factory = Persistence
				.createEntityManagerFactory("JPA");
		EntityManager em = factory.createEntityManager();

		Editora edi = new Editora();
		edi.setNome("TesteNome");
		edi.setEmail("TesteEmail");

		em.getTransaction().begin();
		em.persist(edi);
		em.getTransaction().commit();

		factory.close();

	}
}

my annotated class

package caelum.virtual.gwt.client;

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

@Entity
public class Editora {
	
	@Id 
	@GeneratedValue
	private Long id;
	private String nome;
	private String email;

	public Long getId() {
		return id;
	}
	public void setId(Long id) {
		this.id = id;
	}
	public String getNome() {
		return nome;
	}
	public void setNome(String nome) {
		this.nome = nome;
	}
	public String getEmail() {
		return email;
	}
	public void setEmail(String email) {
		this.email = email;
	}

}

Thank you guys!

Which directory is your persistence.xml?

Is desktop or web?

Maybe this post will help you: Tutorial Hibernate 3 with JPA 2

[Leonardo Terrao]

Thank Hebert Coelho!

I'll take a look at this tutorial!

My project is the Archiving and web pesistencia is in src / META-INF.

have a sense of what could be causing this problem?

[Vijitha Kumara]

Perhaps this might help...

[Leonardo Terrao]

Thank Vijitha Kumara!

I auditioned here according to the link and can not resolve the problem!

Added hibernate-validator-3.0.0.jar, to my class path but it did not... Each time I am lost!

[Vijitha Kumara]

You may need to tell more details on how you run the application? Standalone mode? If so what the exact command?

[Leonardo Terrao]

Hello Vijitha Kumara!
I just solve the problem, this is a generic error can be caused by several factors.

I got resove changing the jars, I think he had any problem with jar, so I was giving the error!


Thank you!
