I'm doing a simple application that save a record in a database. The errors are these:

And the code is:

Session session=HibernateUtil.getSessionFactory().openSession();
Transaction tx=session.beginTransaction();
tx.begin();

Asesor obj=new Asesor();
obj.setPrimerNombre(jTextField2.getText());
obj.setSegundoNombre(jTextField3.getText());
obj.setPrimerApellido(jTextField4.getText());
obj.setSegundoApellido(jTextField5.getText());
obj.setIdAsesor(Integer.valueOf(jTextField1.getText()));

session.save(obj);
tx.commit();
session.close();

¿Any ideas?

Thank you.
