Java Errors with jRuby on Rails on Google App Engine
- by John Wang
I followed all of the instructions so far from:
http://code.google.com/p/appengine-jruby/wiki/RunningRails and
http://gist.github.com/268192
Currently, I'm just trying to get to hello world. I'm getting these
errors when I just run the dev_appserver.rb
238:hello-world jwang392$ dev_appserver.rb .

The server is running at http://localhost:8080/
I'm at a loss at what step I may have missed.
I checked my ruby version (1.8.7) and rails version (2.3.5), gem version (1.3.6) and google-appengine-0.0.10.1
ran:
sudo gem install google-appengine
curl -O
http://appengine-jruby.googlecode.com/hg/demos/rails2/rails2_appengine.rb
ruby rails2_appengine.rb
sudo gem install rails_dm_datastore
sudo gem install
activerecord-nulldb-adapter
put this in my config.ru file:
run lambda { |env|
Rack::Response.new('Hello
World!').finish }
and finally ran
$ dev_appserver.rb .
