Re: Google App Engine Rails Template

I haven't played with it lately so I need to recall..

Well, first of all my dev environment is not a real AppEngine setup,
it's plain JRuby/Rails plus Datastore. That's all I have used so far (no
memcache or mailer). One thing you need to do is require the
appengine-api-1.0-sdk-1.2.1.jar to make the AppEngine stuff available.
I've put the jar in the lib folder and require it in config/development.rb.

I think that's all. By the way, I used this example as project template:
http://github.com/nicksieger/jruby-rack/tree/bb907c03c48eb999e7d099068245b91eeda545bf/examples/rails

I hope this helps!
