You can find out as is explained in chapter 8 of "iText in Action -
Second Edition":
PdfReader reader = new PdfReader(src);
AcroFields form = reader.getAcroFields();
XfaForm xfa = form.getXfa();
if (xfa.isXfaPresent()) System.out.println("XFA form");
Set<String> fields = form.getFields().keySet();
for (String key : fields) {
out.println(key);
}
If you see "XFA form", then your form is created with LiveCycle Designer.
If fields are shown, then the form is hybrid: it contains XFA as well as
AcroFields.
If no fields are shown, only "XFA form", you have a pure XFA form (and
using setField() may not work).
If nothing is shown, you may think you have a form, but you don't.
