Sounds like what HttpUnit does (tries to do):

Well there is no magic possible to have any object model implemented by 
getting something into Rhino, if you use a org.jdom.Document then if 
scripting it with JavaScript in Rhino the properties and methods are 
those defined in the Java API so you could for instance then call
   document.removeContent();
in the script as that is a method
<http://www.jdom.org/docs/apidocs/org/jdom/Document.html#removeContent()>
In addition I think Rhino makes Java getter/setter available as 
properties in JavaScript e.g.
   document.rootElement = someElement
should be possible.

But the browser like HTML Level 0 DOM of making
   document.elementName
properties available for e.g.
   <img name="elementName" />
is not implemented in JDOM and thus if you script a JDOM Document in 
Rhino there is no magic to suddenly have those.
