Thomas,
Yes you can do what you want. You have to set up the java classpath
correctly so that it will find rhino as well as any libraries you want. So
java -cp whatever or -classpath whatever
Then you need to specify that rhino main will run
java -cp whatever org.mozilla.javascript.tools.shell.Main
(note you can also start the rhino debugger instead of the shell).
At this point you will have an interactive shell
If you want to load a javascript file you can also specify the a
-f somefile.js option.
If you get messages about org.mozilla...Main class not found it means
your class path is not set up correctly.
I'm not sure if I have the exact syntax or sequence of arguments, but
that is basically the idea. Good luck. And if you want to do interactive
js, then I highly recommend adding incorporating the jline.ConsoleRunner
which makes it easier.

Hi Ahmed,
I was under the impression that Rhino could be used as a stand-alone
JS engine, and that by running on the JVM, it could seamlessly work
with existing libraries. Is there any good reason that all logic
couldn't be in JavaScript (other than accessing library APIs)?

The usual Rhino usage: your main code is Java, and you embed Rhino to
be able to process JavaScript logic. However, you can implement
needed functions/properties in Java and call them from JavaScript.
In both ways, you have to know how to implement some logic in Java.
Again, we are here if you need help,

Hi Ahmed,
Thanks for the patience. I want to use Rhino to develop web apps with
the
benefit of being able to leverage existing Java libraries. What
sparked my
interest was an interview with Steve Yegge who was tasked with porting
Rails to JavaScript and Google, and who chose Rhino for the project (I
don't intend to port Rails). I've considered other JS engines, but a
large
standard library is essential for web app programming, and Rhino
seems to
be the best in that arena.
My understanding is that with Rhino, my code will be JavaScript, but
that
I'll have to know enough Java to understand library APIs so I can take
advantage of them from within Rhino.
Thomas
