JAXB unmarshalling without XmlRootElement annotation?

Question

Is there any way we can un-marshall for a class without @XmlRootElement annotation? Or are we obligated to enter the annotation?

for example:

public

Following code is used to marshall and unmarshall withot @XmlRootElement

public static void main(String[] args) {

        try {

            StringWriter stringWriter = new StringWriter();

            Customer c = new Customer();
            c.setAge(1);
            c.setName("name");

            JAXBContext jaxbContext = JAXBContext.newInstance(Customer.class);

            Marshaller marshaller = jaxbContext.createMarshaller();
            marshaller.marshal(new JAXBElement( new QName("", "Customer"), Customer.class, null, c), stringWriter);

            Unmarshaller jaxbUnmarshaller = jaxbContext.createUnmarshaller();
            InputStream is = new ByteArrayInputStream(stringWriter.toString().getBytes());
            JAXBElement customer = (JAXBElement) jaxbUnmarshaller.unmarshal(new StreamSource(is),Customer.class);

            c = customer.getValue();

          } catch (JAXBException e) {
            e.printStackTrace();
          }

}

Above code works only if you adding @XmlAccessorType(XmlAccessType.PROPERTY) on Customer class, or make private all attributes.
