Problem in Exporting table to Excel2003

Question

hi,
I have used the sample ExporttoExcel2003 component avaliable for download on the SAP site, for my project.
It downloads the tables into Excel2003 perfectly fine.
<b>however, when the string in the table contains these three characters: & , < , >
then the table doesnt get downloaded into exel2003. I get a XML error.
Maybe its because <> are XML tags and & is considered as a reference.
Is there any way i can bypass this error??? </b>

No Hanoz,
please use this:
private FileInputStream createExcelWorkbook(IWDNode dataNode, Map columnInfos, String fileName) {
   FileInputStream excelCSVFile  = null;
   String attributeName, headerName;
   try {
        File f = new File(fileName);
        WritableWorkbook workbook = Workbook.createWorkbook(f);
        WritableSheet sheet = workbook.createSheet("Report", 0);
        Label labelTitleJXL = null;
        Label labelJXL = null;
        DateTime dateTimeJXL = null;
        Boolean booleanJXL = null;
        StringBuffer strBuff = null;
        IWDNodeElement dataNodeElement = null;
        Object obj = null;
        WritableFont bold = new WritableFont(WritableFont.ARIAL, WritableFont.DEFAULT_POINT_SIZE, WritableFont.BOLD, false, UnderlineStyle.NO_UNDERLINE, Colour.AUTOMATIC);
        WritableCellFormat boldFormat = new WritableCellFormat(bold);
        int j = 0;
        Iterator iter = columnInfos.keySet().iterator();
     IWDMessageManager msg = wdThis.wdGetAPI().getComponent().getMessageManager();
        for (; iter.hasNext(); j++) {
             attributeName = (String) iter.next(); 
             headerName = (String) columnInfos.get(attributeName);
             labelTitleJXL = new Label(j, 0, headerName, boldFormat);
             sheet.addCell(labelTitleJXL);
             for (int i = 0; i < dataNode.size(); ++i) {
                  dataNodeElement = dataNode.getElementAt(i);
                  obj = dataNodeElement.getAttributeValue(attributeName);
                  if (obj instanceof String) {
                       labelJXL = new Label(j, i+1, (String)obj);
                       sheet.addCell(labelJXL);
                  } else if (obj instanceof Date) {
                       strBuff = new StringBuffer();
                       strBuff.append( dataNodeElement.getAttributeValue(attributeName) );
                        String dataString = strBuff.toString();
                         String[] words = dataString.split ("-");
                         String year = words[0];
                         String mounth = words[1];
                         String day = words[2];
                         String formattedString = day + "/" + mounth + "/" + year;
                       labelJXL = new Label(j, i+1, formattedString);
                       sheet.addCell(labelJXL);
//                       Date aDate = (Date)obj;
//                       dateTimeJXL = new DateTime(j, i+1, (Date)obj);
//                       sheet.addCell(dateTimeJXL);
                  } else if (obj instanceof java.lang.Boolean ) {
                       booleanJXL = new Boolean(j, i+1, ((java.lang.Boolean)obj).booleanValue());
                       sheet.addCell(booleanJXL);
        workbook.write();
        excelCSVFile = new FileInputStream(f);
        workbook.close();
   } catch (IOException ex) {
        // Do nothing.
        // This method will return null and an exception will be reported in the method exportToExcel2003 (Failed to create an Excel!)
   } catch (WriteException ex) {
        // Do nothing.
        // This method will return null and an exception will be reported in the method exportToExcel2003 (Failed to create an Excel!)
   return excelCSVFile;
Bye,
