Jaxb not exposed field

Question

I have a class that allows me to do marshaling and unmarshaling.

I would like one of the fields not to be exposed to do internal API processing, but at compile time, the field in question must be specified in the props orders.

@XmlAccessorType(XmlAccessType.FIELD) 
@XmlType(name = "", propOrder = { "fieldOne", "fieldTwo"} )
public class MyClass implements Serializable { 

   protected String fieldOne;

   protected String fieldTwo;

   protected String fieldDontExposed;

   ...

   getters & setters here

}

I would not like to put the fieldDontExposed field in the propOrder.

Thanks for your help !
