deep copy an object using jaxb

deepCopyJAXB.java

public static <T> T deepCopyJAXB(T object, Class<T> clazz) {
  try {
    JAXBContext jaxbContext = JAXBContext.newInstance(clazz);
    JAXBElement<T> contentObject = new JAXBElement<T>(new QName(clazz.getSimpleName()), clazz, object);
    JAXBSource source = new JAXBSource(jaxbContext, contentObject);
    return jaxbContext.createUnmarshaller().unmarshal(source, clazz).getValue();
  } catch (JAXBException e) {
      throw new RuntimeException(e);
  }
}

public static <T> T deepCopyJAXB(T object) {
  if(object==null) throw new RuntimeException("Can't guess at class");
  return deepCopyJAXB(object, (Class<T>) object.getClass());
}

Thanks a lot! It really helps
