Any useful code would be of great help!

Answer 1

This is the code!
import java.io.*;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.util.Locale;
import jxl.Workbook;
import jxl.WorkbookSettings;
import jxl.write.Label;
import jxl.write.WritableCell;
import jxl.write.WritableCellFormat;
import jxl.write.WritableImage;
import jxl.write.WritableSheet;
import jxl.write.WritableWorkbook;
import jxl.write.Number;
import jxl.write.*;
import java.io.IOException;
import java.io.OutputStream;
  public class writeXls
        public String templateName;
        public String outputName;
      public writeXls (String t, String o)
         templateName = "c://"+t;
         outputName = "c://"+o;
      public void writeYearVolume(String []yearvolymeArray)
          WritableWorkbook workbook = null;
          try
              // Setup workbook
              WorkbookSettings ws = new WorkbookSettings();
              ws.setLocale(Locale.UK);
              ws.setEncoding("Windows-31J");
              // Load workbook
              Workbook template = Workbook.getWorkbook(new FileInputStream(templateName));
              // Create new workbook
              workbook = Workbook.createWorkbook(new FileOutputStream(outputName), template, ws);
              // Create new sheet
              WritableSheet sheet = workbook.getSheet(1);
              // Create new label
              Number amc1000= new Number(4, 1, Integer.parseInt(yearvolymeArray[0]));
              Number amc800 = new Number(4, 2, Integer.parseInt(yearvolymeArray[1]));
              sheet.addCell(amc1000);
              sheet.addCell(amc800);
              // Write wookbook
              workbook.write();
              workbook.close();
            catch (IOException e)
              e.printStackTrace();
            catch (WriteException e)
              e.printStackTrace();
            catch(Exception e)
                e.printStackTrace();
  }The xls file is modified but not saved, how do I save the file?
Some of the cells in the xls file contains formulas, because of that, the cells containing formulas dosen't update its value.
if I however save the file manually then the cells are updated. I want to save the xls file automatically from Java.
Any ideas on how to do that?
