PDF generation from Webdynpro for java application

Question

Hi all,
I have a scenario in which a PDF has to be generated from the datils present in a table in the same view, on click of a button. I have found many solutions for generating interactive forms but I need to generate it from the code directly. I have also found an application for generating an excel sheet from the table  data but it is not working with PDF.
So anybody suggest me how to do it or please refer any applications that have been done.
Thanks in advance.

Hi marco,
Sorry for the late reply.
I have got an application to generate an excel file and i will paste that code here for your reference.
    byte[] excelXMLFile;
    IWDCachedWebResource cachedExcelResource = null;
    String fileName = dataNode.getNodeInfo().getName() + ".xls";
    try {
      // create Excel 2003 XML data as a byte array for the given context node, attributes and headers       
      excelXMLFile = this.toExcel(dataNode, columnInfos).getBytes("UTF-8");
      // create a cached Web Dynpro XLS Resource for the given byte array and filename
      cachedExcelResource = this.getCachedWebResource(excelXMLFile, fileName, WDWebResourceType.XLS);
      // Store URL and filename of cached excel resource in context.
      if (cachedExcelResource != null) {
        wdContext.currentContextElement().setExcelFileURL(cachedExcelResource.getURL());
        wdContext.currentContextElement().setExcelFileName(cachedExcelResource.getResourceName());
        // Open popup window with a link to the cached excel file web resource.
        this.openExcelLinkPopup();
      } else {
        wdComponentAPI.getMessageManager().reportException("Failed to create Excel file from table!", true);
    } catch (UnsupportedEncodingException e) {
      wdComponentAPI.getMessageManager().reportException(e.getLocalizedMessage(), true);
    } catch (WDURLException e) {
      wdComponentAPI.getMessageManager().reportException(e.getLocalizedMessage(), true);
In the above code "excelXMLFile" is a byte array in which the data that has to be appended to the pdf (in xml format) is present.
the toExcel method is used to convert the data in the table(i.e., the data that gets populated in the nodes of the view) in to XML format.
My Problem is when i change the filename to .pdf extension and the WDWebResourceType.XLS to WDWebResourceType.PDF and execute the application the Acrobat reader is getting opened but it says
"unsupported file type or the file has been damaged" .
I mean i am unable to put data into the file.
So, please help me in this regard.
