Hi y'all,

I've run into problems while running my program in eclipse. Its a Jruby application that uses Glimmer to create GUI components. I've followed the instructions as in www.indijava.in/community/article/Glimmer-Using-Ruby-to-Build-SWT-User-Interfaces within eclipse, yet I can't seem to get it work. Am trying to run a simple example as the one below:

#require "java"
require "C:/org.eclipse.glimmer.core/src/swt.rb"

class HelloWorld
  include_package 'org.eclipse.swt'
  include_package 'org.eclipse.swt.layout'
  include Glimmer

  def launch
    @shell = shell {
      text "SWT"
      composite {
        label { 
          text "Hello World!" 


Yet, I keep gettint the error below:

C:/Program Files/jruby-1.1.5/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:38:in `require': no such file to load -- facets (LoadError)
	from C:/org.eclipse.glimmer.core/src/glimmer.rb:17
	from C:/org.eclipse.glimmer.core/src/glimmer.rb:16:in `require'
	from C:/org.eclipse.glimmer.core/src/swt.rb:16
	from C:/org.eclipse.glimmer.core/src/swt.rb:5:in `require'
	from hello_world.rb:5

Any suggestions??? :-(

I think you need to install facets gem.

jruby -S gem install facets
