Rhino converts JavaScript scripts into Java classes. Rhino works in both compiled as well as interpreted mode. It is intended to be used in applications, hence there is no support for browser objects that is commonly associated with JavaScript.
Rhino can be used as a debugger by making use of the Rhino shell. It can be used in applications by embedding Rhino.

Granted that JavaScript is not Java and Rhino doesn't support use of compiled Java classes as seamlessly as BeanShell, but it does have a number of other advantages.
Rhino is significantly faster than BeanShell and the difference become more pronounced as the data size increases.
The performance advantage of Rhino alone may not sufficient for me to switch, for most of my programs spend less than 10 percent of the total execution time running BeanShell scripts (rest is spent running Java byte code from existing class libraries), but it certainly is going to be a factor.
A JavaScriptengine (also known as JavaScript interpreter or JavaScript implementation) is an interpreter that interpretes JavaScript source code and executes the script accordingly.
The engine, code named SpiderMonkey, is implemented in C.
The Rhinoengine, created primarily by Norris Boyd (also at Netscape) is a JavaScript implementation in Java.
