Currently i have my code as
bean.setREPO_DATE(row.getCell(16).getDateCellValue());
it works fine if cell is formatted as date in excel.
Try this,
use import org.apache.poi.ss.usermodel.DateUtil;
import org.apache.poi.ss.usermodel.DateUtil;
if(DateUtil.isCellDateFormatted(cell)) { cell.getDateCellValue(); }
