Boa tarde pessoal,
estou tentando fazer o "Hello Word" no JPA com Hibernate mas estou tendo problemas.
criei minha entity@Entity
@Table(name = "contato")
public class Contato {
@Id
@Column(name = "id_contato")
private int id;
@Column(name = "nm_contato")
private String nome;
@Column(name = "email_contato")
private String email;
...gets e sets
public class BussinesObject {
public EntityManagerFactory entityManagerFactory = Persistence
.createEntityManagerFactory("PU");
public EntityManager entityManager = entityManagerFactory
.createEntityManager();
public void inserir(Contato contato) {
entityManager.getTransaction().begin();
entityManager.persist(contato);
entityManager.getTransaction().commit();
entityManager.close();
}
}
Meu persistence.xml no diretório META-INF:
<?xml version="1.0" encoding="UTF-8"?>
<persistence version="1.0"
xmlns="http://java.sun.com/xml/ns/persistence"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/persistence
http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd">

<property name="hibernate.show_sql" value="true" />
<property name="hibernate.query.substitutions" value="true=S, false=N" />
</properties>
</persistence-unit>
</persistence>
public class Main {
public static void main(String[] args) {
Contato contato = new Contato();
contato.setId(1);
contato.setNome("Eduardo");
contato.setEmail("eduaro@aoashdfçlas.com.br");
BussinesObject bussinesObject = new BussinesObject();
bussinesObject.inserir(contato);
}
}
Rodando no servidor e não acontece nada, quando eu chamo rodando como aplicação dá o seguinte erro:
SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".

Por favor, estou procurando na Net e ainda não achei nenhum material passo a passo.
Obrigado
