John,
Thanks so much. One question: why the 'platforms' switch in the Gemfile?

Getting started with Jruby is easy:
Install jruby via rvm: "rvm install jruby; rvm use jruby"
We have something like this in the Gemfile for our app:
platforms :jruby do
gem 'activerecord-jdbc-adapter'
gem 'jdbc-mysql'
gem 'jruby-openssl'
end
platforms :ruby do
gem 'mysql2'
end
then you just "bundle install" and "gem install trinidad", and run
"trinidad
-t" and its just like running "rails server". (The -t param tells
jruby to
use multithreaded mode, with only one copy of the app handling
requests via
multiple threads. If some aspect of your app is not threadsafe
(doubtful
these days), leave off the -t and it will start up multiple
instances of the
app a la Mongrel).
We have found that if you give it enough RAM (like anything related
to Java)
the performance is great, on par with Passenger.
As for downsides, we have bumped our knees on some rough edges, no
doubt
about that, but you trade that time and effort off against the time
saved by
not having to write your own spreadsheet editor and you will most
likely
come out way ahead in the end.
