Okay, I know what is going on...originally I copied the sample codes
from http://en.wikipedia.org/wiki/Rhino_(JavaScript_engine) and add
downloaded rhino to my classpath and believed I am using the latest
rhino (which is NOT!)
So assuming I have with the latest rhino, is it possible to add it
into the javax.script... so I can use a consistent interface like
http://en.wikipedia.org/wiki/Rhino_(JavaScript_engine)?
Thank you!
