-= XmlAdapter =
-JAXB's '''XmlAdapter''' can be used to map classes that would normally be considered "unmappable" - such as classes that do not have a default no-arg constructor, or classes that do not have a natural XML representation.   In a custom subclass of '''XmlAdapter''', you can define define custom code to convert the unmappable class into something that JAXB can handle.  Then, you can use the '''XmlJavaTypeAdapter''' annotation to indicate that your adapter should be used.
-= Example =
-Our first example will use the following domain class:
-<source lang="java">
-package example;
-import java.util.Currency;
-@XmlRootElement
-@XmlAccessorType(XmlAccessType.FIELD)
-public class PurchaseOrder {
-   private Double amount;
-   private Currency currency;
-   ...
-}
