You might want to look at what's been done by dom4j (http://dom4j.org). I know they

dom4j uses factories and interfaces extensively. With the concrete classes used by
JDOM it may be a little more difficult to implement a virtual DOM view, but the dom4j
implementation should at least give some ideas.
