E ae galera,beleza?
Segui o exemplo de hibernate de uma apostila caelum,mas to tento problemas ao tentar inserir um objeto no banco.
Segue a minha classe modelo do objeto:
@Entity
public class EstoqueSucata {
@Id@GeneratedValue
private int Ah;
private int Quantidade;
public int getAh() {
return Ah;
}
public void setAh(int Ah) {
this.Ah = Ah;
}
public int getQuantidade() {
return Quantidade;
}
public void setQuantidade(int Quantidade) {
this.Quantidade = Quantidade;
}
}
Minha classe principal:
public static void main(String[] args) {
// TODO code application logic here
AnnotationConfiguration configuration = new AnnotationConfiguration();
configuration.configure();
SessionFactory factory;
factory = configuration.buildSessionFactory();
Session session = factory.openSession();
EstoqueSucata estoqueTeste = new EstoqueSucata();
estoqueTeste.setAh(100);
estoqueTeste.setQuantidade(50);
Transaction tx = session.beginTransaction();
session.save(estoqueTeste);
tx.commit();
session.close();
}
}
esse é o arquivo XML hibernate.cfg.xml:
<?xml version="1.0" encoding="UTF-8"?>

</hibernate-configuration>
e esse é o erro gerado ao executar o projeto:

Parece que o erro é relacionado ao arquivo xml,o que está errado?
Outra dúvida como gerar o banco de dados a partir das classes de entidade com anotações?
vlw!
