Can't use uuidtools

[pboettcher]

I installed uuidtools in Windows 7 x64 with the command:

jruby -S gem install uuidtools

have written a helper:

require 'rubygems'
require 'uuidtools'

module UUIDHelper
  def self.parse(uuidstring)
    self.uuid = UUID.parse(uuidstring)
  end
  def before_create()
    self.uuid = UUID.timestamp_create().to_s
  end
end

but can't get the application to work. The error message is:

no such file to load -- uuidtools

I searched web pages, tried all possible advices, restarted my Webrick 20 times - still no result. By clicking "Go to declaration" on timestamp_create, NetBeans opens uuidtools.rb - so it CAN find uuidtools. What could be wrong?

irb(main):001:0> require 'uuidtools'

Process Monitor shows me for "require" command:

P.S. It seems to be a general problem with JRuby. Other modules behave in such manner too - they can't be loaded from an application, but from irb they are loaded without problems.

I'm honestly not sure. This one's news to me. I'll download the JRuby runtime for Windows and see if I can duplicate, but I live in Kenya now, so it's uhm... gonna take awhile. :-)

Jambo! You can try to do something (pole, pole), but I'm pretty sure - it is a JRuby configuration bug - not worth your efforts :) Hakuna matata!

Update: That was my lack of knowledge. I should mention uuidtools in Gemfile (but still do not understand why).
