Problem adding the OpenWFEru scheduler code in Initialzers

Hi,

I am using OpenWFEru gem for scheduling the weekly mailing in my rails
application. I have written the scheduler code as a stand-alone ruby
code. So I have to run it separately.

But I want this scheduler to start when I start my rails server. I tried
putting this ruby code in config/initializers. But the server is not
getting started as this scheduler code keeps on running.

Following is my ruby code in config/initializers.

  require 'openwfe/util/scheduler'
  include OpenWFE

  scheduler = Scheduler.new
  scheduler.start

  scheduler.schedule('0 9 * * 1') do
    system "ruby D:\\Projects\\Producteering\\script\\runner
            Person.send_weekly_digest"
  end

  scheduler.join

Am I doing anything wrong? Or is there any way to achieve this?

Thanks in advance...
