I've already sent you the example to add JavaScript
to a field of which you know the object number a while
ago. With this code snippet, you can parse the form
and find out which object number corresponds with
which field:
PdfReader reader = new PdfReader("learning_agreement.pdf");
PdfDictionary catalog = reader.getCatalog();
PdfDictionary form =
(PdfDictionary)PdfReader.getPdfObject((PdfObject)catalog.get(PdfName.ACROFORM));
PdfArray fields =
(PdfArray)PdfReader.getPdfObject((PdfObject)form.get(PdfName.FIELDS));
PdfDictionary field;
PdfObject ref;
PdfName key;
for (Iterator i = fields.listIterator(); i.hasNext(); ) {
ref = (PdfObject)i.next();
System.out.println("Field: " + ref);
field = (PdfDictionary)PdfReader.getPdfObject(ref);
for (Iterator j = field.getKeys().iterator(); j.hasNext(); ) {
key = (PdfName)j.next();
System.out.print(key + ": ");
System.out.println(field.get(key));
}
}
