Ok thank but with old messages I make this method

module Introspection

  class ClassNotFound < Exception ; end


  class Find
    def self.find_class(class_name)
      ObjectSpace.each_object(Module) do |n|
	if n.name==class_name then
	  return n
	end
      end
      raise ClassNotFound
    end
  end


end
