------------------------------------------

Hey Hitesh, 

thanks for the feedback. we could easily change the json to match or be closer. Right now
its configured for POJO output format.  We have a few options: http://jersey.java.net/nonav/apidocs/latest/jersey/com/sun/jersey/api/json/JSONConfiguration.Notation.html

Any input on which one people prefer?  The default is mapped when I turn off POJO and output
is like:

      "finalStatus" : "UNDEFINED",
