Hi,
I faced up with a problem while working with dynamic PDF which I want to do
the same thing that AcroFields.mergeXfaData() did.After couple of days on a
hard work:-) on this problem I could solve at last and I want to share it
with you..Hope it will be helpfull to someone.. Because the ones which I
looked were always need some other classes which I could not find.Here is
the solution.. if anyone who knows the shorter ways to do this pls help me
to improve the solution.
public static void fillPdf( ) {
try {
// take the xml bits
byte[] xmlBits = getBytesFromFile(new
File("C:/dfg.xml"));
// XML parse
DocumentBuilderFactory builderFactory =
DocumentBuilderFactory .newInstance();
builderFactory.setNamespaceAware(true);
org.w3c.dom.Document doc =
builderFactory.newDocumentBuilder() .parse(new
ByteArrayInputStream(xmlBits));
// the result pdf will be in baos
ByteArrayOutputStream baos = new
ByteArrayOutputStream();
// take the template
String templatePath =
"C:\\efatura\\sablon\\rekffo012s6100-ru1gfnpz3uwc00-r1ptfl90muhb00-template_
subform.pdf";
File template = new File(templatePath);
if (!template.exists()) {
throw new IllegalArgumentException("Verilen
PDF şablonu ('"
+ templatePath + "')
bulunamadı.");
} else if (!template.canRead()) {
throw new IllegalArgumentException("Verilen
PDF şablonu ('"
+ templatePath + "') bulundu
ama okunamıyor.");
}
//open the template
PdfReader reader = new PdfReader(templatePath);
// is there XFA ?
if (!reader.getAcroFields().getXfa().isXfaPresent())
{
// if not, you can do smt.
}
