Pessoal to começando a estudar o hibernate com annotation e nao estou conseguindo salvar… seria algum .jar?
dá o seguinte erro…
log4j:WARN No appenders could be found for logger (org.hibernate.cfg.annotations.Version).
log4j:WARN Please initialize the log4j system properly.
Exception in thread "main" org.hibernate.MappingException: Unknown entity: classPersistence.Cliente
segue os códigos da aplicação.
a classe hibernateUtil:
public class HibernateUtil {
private static final SessionFactory sessionFactory;
static {
sessionFactory = new AnnotationConfiguration().configure()
.buildSessionFactory();
}
public static SessionFactory getSessionFactory() {
return sessionFactory;
}
}
segue a classe Cliente e está dentro do Pacote classPersistence
package classPersistence;
import java.io.Serializable;
import javax.persistence.Column;

public void setIdade(Integer idade) {
this.idade = idade;
}
public String getNome() {
return nome;

}
a classe ClienteDao
import org.hibernate.Session;

public void salvar(Cliente cli){
session = HibernateUtil.getSessionFactory().getCurrentSession();
session.beginTransaction();
session.save(cli);
session.getTransaction().commit();
