Sample Code

import javax.xml.bind.JAXBElement;
import javax.xml.bind.JAXBException;
import javax.xml.bind.Marshaller;
import javax.xml.bind.Unmarshaller;
 
 
private MyObject loadObjectFromFile() throws JAXBException{
 
		JAXBElement o=null;
		File inputXml = new File(MY_FILE_NAME);
 
                //Note that the package and mappings need compiled with the JAXB compiler first
		JAXBContext context = JAXBContext.newInstance("net.firstpartners.mypackage");
 
		try{
			InputStream inXmlStream = new FileInputStream(inputXml);
 
			Unmarshaller unmarshaller = context.createUnmarshaller();
			o = (JAXBElement) unmarshaller.unmarshal(inXmlStream);
		} catch (FileNotFoundException fnfe){
			return null;
		} 
 
		return (MyObject) o.getValue();
 
	}
 
	private void saveObjectToXmlFile(MyObject object) throws FileNotFoundException , JAXBException{
 
		FileOutputStream fileOutput = new FileOutputStream( new File(MY_FILE_NAME));
 
		JAXBContext jaxbContext = JAXBContext.newInstance("net.firstpartners.mypackage");
		Marshaller marshaller = jaxbContext.createMarshaller();
