Found it! But some changes are needed.
The comments are in Dutch, and the code assumes that
all the annotations in each page are widget annotations.
I should clean the code up and add more checks.
public static void main(String[] args)
throws IOException, DocumentException {
PdfReader reader = new PdfReader("sworn_DOWA_en.pdf");
// formulier ophalen
PdfDictionary root = reader.getCatalog();
PdfDictionary form = root.getAsDict(PdfName.ACROFORM);
PdfArray fields = form.getAsArray(PdfName.FIELDS);
// fields is leeg en dit zou niet mogen
// pagina's ophalen
PdfDictionary pages = root.getAsDict(PdfName.PAGES);
PdfArray kids = pages.getAsArray(PdfName.KIDS);
PdfDictionary page;
// annotaties van de pagina toevoegen als form fields
PdfArray annots;
for (int i = 0; i < kids.size(); i++) {
page = (PdfDictionary)kids.getDirectObject(i);
annots = page.getAsArray(PdfName.ANNOTS);
for (int j = 0; j < annots.size(); j++) {
fields.add(annots.getPdfObject(j));
}
}
// de gewijzigde file saven
PdfStamper stamper = new PdfStamper(reader,
new FileOutputStream("new_form.pdf"));
stamper.close();
// testen welke velden er gevonden worden
reader = new PdfReader("new_form.pdf");
AcroFields formfields = reader.getAcroFields();
for (Iterator i = formfields.getFields().keySet().iterator();
i.hasNext();) {
System.out.println(i.next());
}
}
