Greetings,
I am using itext 5.2.1 and attempting to read the data from the
xfa_enabled.pdf (included in the iText in Action tutorial book) PDF
containing an XFA form. Below is the sample code:
public void readData(String src, String dest)
throws IOException, ParserConfigurationException, SAXException,
TransformerFactoryConfigurationError, TransformerException {
FileOutputStream os = new FileOutputStream(dest);
PdfReader reader = new PdfReader(sr
http://itext-general.2136553.n4.nabble.com/file/n4647963/xfa_enabled.pdf
xfa_enabled.pdf c);
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;
}
}
list = node.getChildNodes();
for (int i = 0; i < list.getLength(); i++) {
if("movies".equals(list.item(i).getLocalName())) {
node = list.item(i);
break;
}
}
Transformer tf = TransformerFactory.newInstance().newTransformer();
tf.setOutputProperty(OutputKeys.ENCODING, "UTF-8");
tf.setOutputProperty(OutputKeys.INDENT, "yes");
tf.transform(new DOMSource(node), new StreamResult(os));
reader.close();
}
This works correctly. I then manually change some of the values in the
generated xml and attempt to fill in a pdf with the updated data using the
below code:
public static void fillData3(String src, String xml, String dest)
throws IOException, DocumentException, ParserConfigurationException,
SAXException {
boolean preserve = true;
PdfReader reader = new PdfReader(src);
PdfStamper stamper = null;
try {
// preserve the reader enabling by creating a PDF in append mode (or
not)
if (preserve) {
stamper = new PdfStamper(reader, new FileOutputStream(dest),
'\0', true);
} else {
stamper = new PdfStamper(reader, new FileOutputStream(dest));
}
AcroFields form = stamper.getAcroFields();
XfaForm xfa = form.getXfa();
xfa.fillXfaForm(new FileInputStream(xml));
} finally {
if (stamper != null) {
try {
stamper.close();
} catch (Exception e) {
e.printStackTrace();
}
}
}
}
This also seems to work correctly and I can open the generated PDF with the
updated fields with Adobe Reader 10.1.3
However, when I attempt to read the data from the generated pdf using the
readData method, I get the below error:
Exception in thread "main" ExceptionConverter: java.io.EOFException

at com.itextpdf.text.pdf.PdfStamper.getAcroFields(PdfStamper.java:383)
Any ideas on what could be the cause as this seems to be occuring even for
other XFA PDF's that I am working on. I have attached the xfa_enabled.pdf
file.
Kind Regards,
Dee
