private void requestMarshall(CreateOrderRequest request){

      QName qName = new QName("http://deneme//EmployeeTypes", "CreateOrderRequest");
      JAXBElement<CreateOrderRequest> root = new JAXBElement<CreateOrderRequest>(qName, CreateOrderRequest.class, request);
      jaxbMarshaller.marshal(root, stringWriter);
      String result = stringWriter.toString();
      getLogger().warn("Create order request XML: {}" ,result);
   }catch (JAXBException jb){
      getLogger().error("Create order request XML marshall error: {}" ,jb);

}

When we have something like this in our Request object 

typeDesc.setXmlType(new QName("http://deneme/ManagementTypes", ">CreateOrderRequest"));
