Popular Jtable with BD data without using Defaulttablemodel

Question

I’m doing a whole layered project and I read somewhere that the use of Defaulttablemodel is not very recommended. I am trying to receive values registered in the BD and fill a jTable with these values. Below follow the classes defined.

DAO Layer Method to List Registered Persons:

 public List listarTodas() throws SQLException, ClassNotFoundException {

   List lista;
   try (Connection conn = ConnectionFactory.getConnectionFactory()) {
     lista = new ArrayList();
     String sql = "SELECT * FROM Pessoa";
     try (PreparedStatement st = conn.prepareStatement(sql)) {
         ResultSet rs = st.executeQuery();
         while (rs.next()) {
             Pessoa p = resultSet2Model(rs);
             lista.add(p);
         }
     }
}
    return lista;

}

I believe that now one should implement the Business and View Layers. That’s not it?
