Apache poi

Voila le genre de code que j'ai fais:

package testpoi2;

import Model.Opcvm;
import java.io.FileInputStream;
import java.util.Iterator;
import org.apache.poi.hssf.usermodel.HSSFCell;
import org.apache.poi.hssf.usermodel.HSSFRow;
import org.apache.poi.hssf.usermodel.HSSFSheet;
import org.apache.poi.hssf.usermodel.HSSFWorkbook;
import org.apache.poi.poifs.filesystem.POIFSFileSystem;

public class testpoi3 {

public static void main(String[] args) {

String fileName = "C:\\Users\\BILO\\Desktop\\BNS\\sicavtest.xls";
HSSFCell[][] cellHolder = ReadExcel(fileName);




//
}

public static HSSFCell[][] ReadExcel(String fileName) {
String[][] HSSFCell = new String[1000][1000];
HSSFCell[][] cellHolder = new HSSFCell[1000][1000];
try {
FileInputStream myInput = new FileInputStream(fileName);
POIFSFileSystem myFileSystem = new POIFSFileSystem(myInput);
HSSFWorkbook myWorkBook = new HSSFWorkbook(myFileSystem);
HSSFSheet mySheet = myWorkBook.getSheetAt(0);
Iterator rowIter = mySheet.rowIterator();
int i = 0;
while (rowIter.hasNext()) {
int j = 0;
HSSFRow myRow = (HSSFRow) rowIter.next();
Iterator cellIter = myRow.cellIterator();
while (cellIter.hasNext()) {
Opcvm o = new Opcvm();
HSSFCell myCell = (HSSFCell) cellIter.next();
cellHolder[i][j] = myCell;
j++;

if ((j == 1) && myCell.getCellType() == myCell.CELL_TYPE_NUMERIC) {
o.setIdopcvm(myCell.toString());
o.getIdopcvm();
continue;
} else if ((j == 1 || j == 2) && myCell.getCellType() == myCell.CELL_TYPE_STRING) {
o.setDenomination(myCell.getStringCellValue());
continue;

} else if ((j == 3) && myCell.getCellType() == myCell.CELL_TYPE_STRING) {
o.setGestionnaire(myCell.getStringCellValue());

continue;
} else if ((j == 4) && myCell.getCellType() == myCell.CELL_TYPE_NUMERIC) {
o.setDouverture(myCell.getDateCellValue());
continue;
} else if ((j == 5) && myCell.getCellType() == myCell.CELL_TYPE_NUMERIC) {
o.setVldebutannee((float)myCell.getNumericCellValue());
System.out.println(o);
continue;

}

}
i++;
}
} catch (Exception e) {
e.printStackTrace();
}
return cellHolder;

}
}


et ça ne me permet pas d'extraire tout les cellules.
peux tu me donner ton avis?
