How to change xml declaration using jaxb Marshaller

Question

please, my xml declaration, in the output file generated by jaxb: javax.xml.bind.Marshaller is:
<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
I need to change it in:
<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet type="text/xsl" href="style.xsl"?>
I don't have idea about how to change.
thanks a lot alessandro

Hello.
public void saveJaxbObjectToFile(String packageName, Object myJaxbObject, String fileName)
throws JAXBException, ParserConfigurationException, TransformerConfigurationException,
TransformerException, FileNotFoundException, IOException {
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
dbf.setNamespaceAware(true);
DocumentBuilder db = dbf.newDocumentBuilder();
org.w3c.dom.Document document = db.newDocument();
JAXBContext jAXBContext = JAXBContext.newInstance(packageName);
Marshaller m = jAXBContext.createMarshaller();
m.marshal(myJaxbObject, document);
ProcessingInstruction processingInstruction = document.createProcessingInstruction("xml-stylesheet", "type=\"text/xsl\" href=\"style.xsl\"");
Node rootElement = document.getDocumentElement();
document.insertBefore(processingInstruction, rootElement);
TransformerFactory transformerFactory = TransformerFactory.newInstance();
Transformer transformer = transformerFactory.newTransformer();
transformer = transformerFactory.newTransformer();
transformer.setOutputProperty("indent", "yes");
transformer.setOutputProperty("encoding", "UTF-8");
transformer.setOutputProperty("version", "1.0");
FileOutputStream fos = new FileOutputStream(fileName);
transformer.transform(new DOMSource(document), new StreamResult(fos));
fos.flush();
fos.close();
Good luck.
