Answer 1

This error implies that your adddriver only has 6 columns, so 8 is an invalid column index.

This means all of these statements have invalid indices :

            one.add(rs.getString(8));
            one.add(rs.getString(9));
            one.add(rs.getString(10));
            one.add(rs.getInt(11));

Perhaps your DB table doesn't contain what you think it does.
