I could succesfully develope an application for uploading an excel file and displaying the data in tabular format (i.e through table  display ) .  But on  Action <<Export TO Table>> it is not showing the details in tabular format . After uploadinfg file it is providing successful msg but when i m clicking on Export to table it is not displaying table data .
Its a demo WD program in java given below
Could anybody please guide me in this approach ?
public void onActionUploadFileData(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )
    InputStream text = null;
    int temp = 0 ;
    String path ;
    try
            File file = new File(wdContext.currentContextElement().getResource().getResourceName().toString());
            FileOutputStream output = new FileOutputStream(file);
            if (wdContext.currentContextElement().getResource()!= null )
                  text = wdContext.currentContextElement().getResource().read(false);
                  while ((temp=text.read())!= -1)
                        output.write(temp);
            output.flush();
            output.close();
            path = file.getAbsolutePath();
            wdComponentAPI.getMessageManager().reportSuccess(path);
    catch (Exception ex)
      ex.printStackTrace();
  public void onActionExport_To_Table(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )
    //@@begin onActionExport_To_Table(ServerEvent)
    try {
      Workbook workbook = Workbook.getWorkbook(new File(path));
      Sheet sheet = workbook.getSheet(0);
      int columns = sheet.getColumns();
      int rows = sheet.getRows();
      int i=0;
      int j;
      for (j=1;j<=rows;j++)
            element = wdContext.nodeTableData().createTableDataElement();
            Cell cell1 = sheet.getCell(i,j);
            element.setEmpId(cell1.getContents());
            Cell cell2 = sheet.getCell(i+1,j);
            element.setFirstname(cell2.getContents());
                  Cell cell3 = sheet.getCell(i+2,j);
                  element.setLastname(cell3.getContents());
                  wdContext.nodeTableData().addElement(element);
     catch (Exception ex)
            ex.printStackTrace();

Hi Trina,
Check onAction method(onActionExporttotable) of "Export to Table ". Print the c1.getContents(), c2.getContents,c3.getContents value with MessageManager while setting vaule to node attribute.
Once the all the attribute added to node TableData, print the table attribute in onActionExporttotable method itself.
Also check the TableData node properties which is bind to table of displaying in the screen.
Hopt it helps
