Exception running dev_appserver.rb

Ruby JRuby

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:

require ‘config/environment’

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
