Combining XFA with PDFBox

Question

I would like to fill a PDF form with the PDFBox java library. The PDF form is created with Adobe Live Designer, so it uses the XFA format.

I try to find resources ab

The question specifically identifies the PDFBox library in the subject; you do not need iText, the XFA manipulation can be done using the PDXFA object available in PDFBox 1.8.

Many thanks to Maruan Sahyoun for his great work on PDFBox + XFA.

This code only works when you remove all security on the PDDocument.
It also assumes the COS object in PDXFA is a COSStream. The simplistic example below reads the xml stream and writes it back into the PDF.

 PDDocument doc = PDDocument.load("filename");
 doc.setAllSecurityToBeRemoved(true);

 PDDocumentCatalog docCatalog = doc.getDocumentCatalog();
 PDAcroForm form = docCatalog.getAcroForm();

 PDXFA xfa = form.getXFA();
 COSBase cos = xfa.getCOSObject();
 COSStream coss = (COSStream) cos;
 InputStream cosin = coss.getUnfilteredStream();
 Document document = documentBuilder.parse(cosin);

 COSStream cosout = new COSStream(new RandomAccessBuffer());
 OutputStream out = cosout.createUnfilteredStream();

 TransformerFactory tFactory = TransformerFactory.newInstance();
 Transformer transformer = tFactory.newTransformer();
 DOMSource source = new DOMSource(xmlDoc);
 StreamResult result = new StreamResult(out);
 transformer.transform(source, result);

 PDXFA xfaout = new PDXFA(cosout);
 form.setXFA(xfaout);
