Answer 1

By default a JAXB impl will treat public properties (get/set) method pairs as mapped. If you want to annotate the field you need to put #XmlAccessorType( XmlAccessType.FIELD) on your class.
http://blog.bdoughan.com/2011/06/using-jaxbs-xmlaccessortype-to.html
If you are using EclipseLink JAXB (MOXy) as your JAXB (JSR-222) provider (I'm the MOXy) lead then you can use the #XmlInverseReference extension.

Answer 2

Move the #XmlTransient to the get method of the class that uses the mappedBy option (the inverse side of the relation).
