I tried to run this example as
1) standalone
2)Using “ant run-java-ar”

In both cases i got the same above error
[java] org.jruby.exceptions.RaiseException: cannot load Java class JavaLang
[java] unable to load language: ruby: org.jruby.exceptions.RaiseException: cannot load Java class JavaLang

Please let me know if i need to set anything in the classpath?

Just tried your code. I had an error with connection to database. After knocking my head on the keyboard I found a mistake in your code (at least for me it was a mistake).
In the code ActiveRecord::Base.establish_connection … you wrote :user => “root” - well it should be :username => “root”.
The way I found out the error was - I ran the script and got a error for mysql connection - connection from root@192.168.*.* is forbidden. But I set :user => ‘my_correct_login’. So as :user was not valid option it was just ignored, so “root” was used instead by default.

I’m using the latest version of the IDEA EAP IDE as well as the latest version of the Ruby plugin.

I want to ask you about integration JRuby to Idea, without highlighting errors in: require ‘rubygems’
