Backgroundrb devel - Jul 2006 - ''uninitialized constant'' error

Hi All,

I am fairly new to Ruby and backgroundRB.  I am trying to run a simple example
in Windows to get my feet wet with backgroundRB and am running into an
''uninitialized constant'' error when I invoke the controller on
my rails app.

In ''MyTest'' Controller
-------------------
def longrun
      session[:job_key] = MiddleMan.new_worker(:class => :tail_worker, :args
=> {:baz => ''hello!'', :qux => ''another
arg!''})
  end

In cookbook\lib\workers\tail_worker.rb
-----------------------------------------------
class TailWorker < BackgrounDRb::Rails
  def do_work(args)
    puts "Printing from inside TailWorker::do_work()"
  end
end


When I issue the request to 
http://127.0.0.1:3000/My_Test/longrun
I get the following error:
NameError in My testController#longrun
uninitialized constant TailWorker


I''d appreciate any light thrown on what I might have done to cause this
error and about how to rectify it.

Thanks,
Aravind Elango

Hi Aravind and welcome ;) Your code looks like it should work fine.  
Did you make sure to restart the backgroundrb server after you added  
the tails_worker.rb file to lib/workers? That could cause this error.

Gotcha. Restarting the server worked.
Thanks Ezra :-)
