title: Is there "native" support for JSON in JDK6 Script Engine?
body: <p>I'm using JDK6the standard  Scripting.  I need to store and retrieve some JavaScript Objects that also contain Java Objects to JSON.  I loaded the json2.js into the ScriptENgine and can use it fine without issue if the objects are all created in the Scrip Engine.  The moment I try to use my own Java classes, I get some errors like "object does not support toJSON" errors.  </p>
  
  <p>I did not find much about JSON in Java Scripting / Rhino context.</p>
  
  <p>Am I doing something totally wrong?  What's the best way of achieving the requirement?</p>
