Greetings All,

I have concluded that I ought to try out JRuby.  Running on windows I
get the short end of the stick when it comes to non-ruby-native
functionality, and there is an AI package in Java that I want to play
with in a language that doesn't require a novel worth of code to use.  I
have a few questions about how to make this happen:

1) What is the best way to get MRI and JRuby to live on the same
(Windows) system?  The only answer I've found to this question involves
bash scripts.

2) What do I need to get in terms of a Java Environment.  below is the
output of Java -version:
  java version "1.4.1_03"
  Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.1_03-b02)
  Java HotSpot(TM) Client VM (build 1.4.1_03-b02, mixed mode)
This was likely installed at least 3 years ago, and is probably out of
date.  I went to java.sun.com to look for "the latest version" and hit
buzzword central.  The last time I did anything more then run a Java App
was 6+ years ago and I'm now lost in all the new Lingo.  So, what to I
need to run JRuby, and what else outh I get to make Rails work with it?

3) Is is possible to "move" my installed gems from MRI Ruby1.8.6 to
JRuby without having to touch the network.  All I have is a 56.6k modem,
and Downloading rails again is a 4 hour job. (BTW: Is there a way in
general to download a gem and not install it? For example could I get
the latest Rails release on my Laptop at work and bring the files home
to install on the desktop?)

4) What does it take to get SQLite or some equivalent no configuration
database running in JRuby?

Thanks for the help.
