System.out.println("AvlbYN "+row.getAttribute("RlstdAvlblYn"));
System.out.println("RlstdUnitId "+row.getAttribute("RlstdUnitId"));

Vishwesh,
I'd start with something along the lines of ...
    RowSet vo = (RowSet)getRealEstatePropertyUnitDetailsVO();
    vo.reset();
    while (vo.hasNext())
      Row row = vo.next();
      row.setAttribute("Attribute", value);
    }getAllRowsInRange() may exclude some rows outside the "range". Also, the vo.reset is needed since your View Object currency may not be at the beginning of your RowSet.
Hope that helps.
