The problem is that JAXB must be able to provide the XmlAdapter
with a POJO *class* object representing the XML data. If this is defined by
an
interface in manually written Java code, then there's no way JAXB
can instantiate this intermediary representation.
For marshalling, your XmlAdapter produces an object implementing
the interface, but here JAXB merely has to use the getters to
create a DOM element.
Preferably, such services should define the XML interface by an
XML schema, which would let you generate XML on the client
and/or server side via Java code derived from the XML schema,
and then such problems do not arise.
