import org.apache.poi.hssf.usermodel.HSSFSheet;
import org.apache.poi.hssf.usermodel.HSSFWorkbook;

public class ReadExcel2003 {
    public static void main(String[] args) {
        try {
            FileInputStream file = new FileInputStream("C:\\dd.xls");
            
            HSSFWorkbook workbook = new HSSFWorkbook(file);
            HSSFSheet sheet = workbook.getSheetAt(0);
            HSSFRow row = null;

            for(int i=0;sheet.getRow(i)!=null;i++){

                for(int j=0;row.getCell(j)!=null;j++){
