BackgrounDRb - uninitialized constant

I installed BackgrounDRB as instructed:

script/plugin install svn://rubyforge.org//var/svn/backgroundrb
rake backgroundrb:setup

I started it with:
rake backgroundrb:start

In a model I make the call:

MiddleMan.new_worker :class => :rss_worker

In /lib/workers I have file rss_worker.rb, which contains the class:

Class RssWorker < BackgrounDRb::Rails

def do_work(args)

end
end

It seems like I have everything setup right, but I get the following
NameError:

uninitialized constant RssWorker

Any ideas? It’s probably something dumb, but I can’t seem to figure it
out.

Hey Justin-

Have you restarted the rb server since you put your worker class in

the lib dir? You have to restart the drb server to pick up new files
you put in lib/workers. Oh actually now that I look at your code
again I see that you have misspelled class as Class. Is this just a
typo or is this also in your worker class code?

Class RssWorker < BackgrounDRb::Rails

should be

class RssWorker < BackgrounDRb::Rails

I restarted webrick and also issued the commands

rake backgroundrb:stop
rake backgroundrb:start

again I see that you have misspelled class as Class. Is this just a
typo or is this also in your worker class code?

Woops. Yes, that is just a typo in the post. It is “class” in the
code.

Ok. I had used:

rake backgroundrb:stop

and CTRL-C to kill my webrick.

Did this a bunch of times. Then I thought to check Activity Monitor -
and sure enough, two Ruby instances were still alive! So I hand killed
these, restarted everything - and the error went away.

I have a similar problem trying to get BackgroundRb to work - the error
message I get is

undefined method ‘start process’ for nil:NilClass

My install went ok but strangely this command didn’t work

script/backgroundrb/start -p 11111 -d

I get the error

start: invalid option: -p

So instead i’ve done

script/backgroundrb/start -d

which seems ok but when my controller calls my worker I get

undefined method ‘start process’ for nil:NilClass
