Leandro…Blz?
Olha só…eu to estudadndo esse material que vc me enviou, que por sinal é muito bom, só que tá dando um errinho no meu projeto…no primeiro exercicio que cria o metodo save().
Queria um help seu pra que eu consiga evoluir nesse passo…
Minhas classes e arquivos são:
HibernateUtil.java;
Cliente.java;
ClienteDAO;
Principal.java;
hibernate.cfg.xml;
segue abaixo as classes e o erro:
HibernateUtil.java
package teste;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.AnnotationConfiguration;
public class HibernateUtil {
private static final SessionFactory sessionFactory;
static {
try {
// Create the SessionFactory from hibernate.cfg.xml
sessionFactory = new AnnotationConfiguration().configure().buildSessionFactory();
} catch (Throwable ex) {
// Make sure you log the exception, as it might be swallowed
System.err.println("Initial SessionFactory creation failed." + ex);
throw new ExceptionInInitializerError(ex);
}
}
public static SessionFactory getSessionFactory() {
return sessionFactory;
}
}
Cliente.java;
package teste;

import javax.persistence.Column;
import javax.persistence.Entity;

@Entity
@Table(name = "cliente")
public class Cliente implements Serializable {
@Id @GeneratedValue(strategy = GenerationType.AUTO)
private Long id;
@Column(name = "nome_cliente", nullable = false, length=60)
private String nome;
@Column(name = "idade", nullable = false, length = 5)
private Long idade;
public Cliente(){
super();
}
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 Long getIdade() {
return idade;
}
public void setIdade(Long idade) {
this.idade = idade;
}
}
ClienteDAO;
[code]
package teste.dao;
import org.hibernate.Session;
import teste.Cliente;

public class ClienteDAO {
private Session session;
public ClienteDAO(){

session.save(cli);
session.getTransaction().commit();
}
}[/code]
Principal.java
package teste;

clienteDAO.salvar(c1);
clienteDAO.salvar(c2);
