It's just that, when I do the insert right through MarcaDAO :

MarcaDao marcadao = new MarcaDao();
marcadao.insert(marca);

It works normally.

But when I pass through controller , which passes to the façade , it displays the above error:

int result = 0;

                if (idMarca == null) {
                    System.out.println("ADD");
                    result = new MarcaController().addMarca(marca);
                } else {
                    marca.setMarcaID(idMarca);
                    result = new MarcaController().updateMarca(marca);
                    idMarca = null;
                }

Then the error does not give MarcaDAO .

Upload the project to mega, for anyone who can help me take a look. It has the database in SQLServer 2005 as well.
