Exception running dev_appserver.rb

[joshmoore-3]

Hi,

I have been working off this tutorial http://docs.google.com/View?id=d656rh6_36f7j9qzc3 
  trying to setup a Rails application, with datamapper that will run  
an GAE.  I have followed all the steps (I believe correctly).  But,  
whenever I run the dev_appserver.rb I get this exception:

=> Generating configuration files
/Users/joshmoore/.gem/jruby/1.8/gems/appengine-apis-0.0.9/lib/

Here is the output of  the "appcfg.rb gem list" command:
=> Running RubyGems

*** LOCAL GEMS ***

actionmailer (2.3.3)
actionpack (2.3.3)
activerecord (2.3.3)
activeresource (2.3.3)
activesupport (2.3.3)
addressable (2.1.0)
appengine-apis (0.0.9)
dm-appengine (0.0.5)
dm-ar-finders (0.10.1)
dm-core (0.10.1)

dm-validations (0.10.1)
extlib (0.9.13)
rack (1.0.0)
rails (2.3.3)
rake (0.8.7)

The config.ru file looks like this:

require 'appengine-rack'
AppEngine::Rack.configure_app(
   :application => 'jsm277',
   :sessions_enabled => true,
   :version => 'dm_test')
AppEngine::Rack.app.resource_files.exclude :rails_excludes
ENV['RAILS_ENV'] = AppEngine::Rack.environment
require 'config/environment'
run ActionController::Dispatcher.new


I would appreciate all advice to help fix this problem.  Thanks in  
advance.

The google-appengine 0.0.5 tools now support gem bundler but not rubygems.
Rails 2.3 will not work without rubygems, so we are dropping Rails support
until the remaining Rails 3.0.pre gems are released (which will be very soon).

Hi All please ignore this.  After posting it I released that the jar  
files for app engine were corrupt.

Sorry,

Josh
