JAXB unmarshal with declared type does not populate the resulting object with data

Question

I am trying to unmarshal a given XML:

 rewriting of file
 toolA

        

Answer 1

Try to remove following code, and try again:

  @XmlType(name = "", propOrder = {
     "tx",
     "toolId",
     "toolVendor",
     "toolVersion",
     "userName",
     "commonProperties",
     "extensions"
    })

Answer 2

Your XML document does not match the namespace qualification that was defined in your mappings (see: http://blog.bdoughan.com/2010/08/jaxb-namespaces.html). You could leverage an XMLFilter to apply a namespace to your XML document during the unmarshal operation.

import org.xml.sax.*;
import org.xml.sax.helpers.XMLFilterImpl;

public class NamespaceFilter extends XMLFilterImpl {

    private static final String NAMESPACE = "htp://www.example.com/mdf/v4";

    @Override
    public void endElement(String uri, String localName, String qName)
            throws SAXException {
        super.endElement(NAMESPACE, localName, qName);
    }

    @Override
    public void startElement(String uri, String localName, String qName,
            Attributes atts) throws SAXException {
        super.startElement(NAMESPACE, localName, qName, atts);
    }

}

Below is an example of how you would leverage the XMLFilter during an unmarshal.

    // Create the XMLFilter
    XMLFilter filter = new NamespaceFilter();

    // Set the parent XMLReader on the XMLFilter
    SAXParserFactory spf = SAXParserFactory.newInstance();
    SAXParser sp = spf.newSAXParser();
    XMLReader xr = sp.getXMLReader();
    filter.setParent(xr);

    // Set UnmarshallerHandler as ContentHandler on XMLFilter
    Unmarshaller unmarshaller = jc.createUnmarshaller();
    UnmarshallerHandler unmarshallerHandler = unmarshaller
            .getUnmarshallerHandler();
    filter.setContentHandler(unmarshallerHandler);

    // Parse the XML
    InputSource xml = new InputSource("input.xml");
    filter.parse(xml);
    Object result = unmarshallerHandler.getResult();

Answer 3

How do you have annotated the classes BaseName , BaseVersion and TX?

If you have not annotated these classes, you will annotated the String inside of this classes as @XmlValue

Answer 4

Change BaseName and TX to String and it shall work. As it is the xml doesn't comply with your schema, which is represented by the class in this case.
