I was using Apache POI 3.9. I recently switch to Apache poi-ooxml 3.9 and I have now some problems with:

import org.apache.poi.ss.util.RegionUtil

because it didn't exist so I would like to know if there if a class that have similar methods?

RegionUtil.setBorderLeft((short)(int)objFormato.getObjBordeIzquierda().getIntTipoLinea(), range, objInWorkSheet , objWorkBook);

RegionUtil.setLeftBorderColor(IndexedColors.valueOf(objFormato.getObjBordeIzquierda().getStrColor()).getIndex(), range, objInWorkSheet, objWorkBook);
