If the XML document is invalid, the catch block prints the details. /** * Helper method that returns a validator for our Addon XSD * * @param version The version number, in range * @param handler A .* * @param url * the Schema URL * @param context * the SAXB context * @param handler * the SAX handler * @param resolver * the SAX resolver * @return the unmarshaler * @throws JAXBException * @throws SAXException */ private Unmarshaller create Unmarshaler(URL url, JAXBContext context, Handler handler, Resolver resolver) throws JAXBException, SAXException /** * Creates an unmarshaler using the given factories and sream.

In this case, validating your XML against schemas becomes a real nightmare.

* * @param stream * the Schema stream * @param context * the SAXB context * @param handler * the SAX handler * @param resolver * the SAX resolver * @return the unmarshaler * @throws JAXBException * @throws SAXException */ private Unmarshaller create Unmarshaler(Input Stream stream, JAXBContext context, Handler handler, Resolver resolver) throws JAXBException, SAXException /** * Reads the XML formatted string from the provided transport Reader, and resurrects the object graph * found within the transport Reader.

* * @param transport Reader The Reader holding a single XML-formatted String being converted by the marshal method * in an Xml Binder of the same internal implementation as this one.
