<title>upload excel data














/*We need to something to iterate through the cell */

What I have tried:

ps.setString(1,((HSSFCell)cellStoreArrayList.get(0)).toString());
              ps.setString(2,((HSSFCell)cellStoreArrayList.get(1)).toString());
              ps.setString(3,((HSSFCell)cellStoreArrayList.get(2)).toString());
                count= ps.executeUpdate();
