Thank you for your responses. I have tried your example but it does the same
thing. Interestingly, the XML does seem to be updated with the updated value
but is not reflected in the actually PDF. After getting the data node:
XfaForm xfa = new XfaForm(reader);
Node node = xfa.getDatasetsNode();
NodeList list = node.getChildNodes();
for (int i = 0; i < list.getLength(); i++) {
if("data".equals(list.item(i).getLocalName())) {
node = list.item(i);
break;
}
}
and after updating values within the Node I fill in the XFA:
AcroFields vStamperForm = stamper.getAcroFields();
XfaForm xfaForm = vStamperForm.getXfa();
xfaForm.fillXfaForm(node);
I then write the Node contents to an xml file:
FileOutputStream os = new FileOutputStream("resource/updatedData.xml");
Transformer tf = TransformerFactory.newInstance().newTransformer();
tf.setOutputProperty(OutputKeys.ENCODING, "UTF-8");
tf.setOutputProperty(OutputKeys.INDENT, "yes");
tf.transform(new DOMSource(node), new StreamResult(os));
The updatedData.xml file has the updated value to the 'stubborn_field' but
the actual PDF displays an empty stubborn_field value. All other fields are
correctly updated both reflecting in the updatedData.xml and the generated
PDF.
