Hi,
I do not think the Java type you are using is supported by JAXB i.e.
it does not know, by default, how to convert an instance of
Map<String, List<String>> to/from XML.
You may need to utilize an XmlTypeAdapter. I recommend searching the
JAXB users archive:
http://www.nabble.com/java.net---jaxb-users-f13500.html
and posting a question to that list.
Paul.
