I have a simple little test code that can read the data from an XFA form.
When I run it on a digitally signed form, all I get is one field for the
signature itself. How can I extract the actual form content covered by the
signature?
Thanks,
public static void main(String[] args) {
try {
PdfReader reader = new PdfReader("PPF.pdf");
PdfDictionary root = reader.getCatalog();
PdfDictionary acroform =
root.getAsDict(PdfName.ACROFORM);
acroform.remove(PdfName.XFA);
AcroFields form = reader.getAcroFields();
Map<String,Item> fields = form.getFields();
for (String field : fields.keySet()) {
System.out.println(field);
System.out.println(form.getField(field));
}
reader.close();
} catch (IOException e) {
e.printStackTrace();
}
}
