Read adobe form element

Question

Hello all,
I have an application which must send and receive mail with PDF attachment. The send part is already working. The PDF is created with adobe interactive forms.
The receive of the PDF is partly working. I can get the mail and the PDF source and display the PDF file. But I need the fields on that PDF file to populate 2 badis. I don't know how I can do that.
I use WAS 6.40 SP 18 and developer studio SP 18.
Thanks in advance,
Patrick Willems

Hi Patrick,
It can be done by directly using the PDFObject API, e.g.
  private byte[] getData(byte[] pdf) throws IOException {
    IPDFObject pdfObject = (IPDFObject) WDPDFObjectFactory.getPDFObject();
    pdfObject.setPDF(copy(pdf));
    pdfObject.setTraceLevel(0); // 0 - 4
    InputStream in = pdfObject.getData();
    return in == null ? null : IOUtils.toByteArray(in);
  private ByteArrayOutputStream copy(byte[] in) throws IOException {
    ByteArrayOutputStream out = new ByteArrayOutputStream(in.length);
    out.write(in);
    return out;
This gives you the data.xml that you can parse using a SAX parser.
On the other hand, you say you can display the pdf. I suppose you use an InteractiveForm UI element? Then the fields in the pdf's template are bound to the Web Dynpro context. Isn't the context being populated when you set the value of the <i>pdfSource</i> attribute? Maybe invalidate the <i>dataSource</i> node before setting the value of <i>pdfSource</i>? I don't use this particular scenario and I'm not sure it works.
Kind regards,
