There is something wrong with your setup. MetaWorker shouldn't be even shown in controller/rails part of things.

Can you post your worker code and how are you invoke BackgrounDRb worker tasks from rails?

This is my worker definition. I use ruby script/generate worker MakeView to generate this worker.

class MakeViewWorker < BackgrounDRb::MetaWorker   set_worker_name :make_view_worker   attr_reader :process   def create(args)     # this method is called, when worker is loaded for the first time     process=0     while process < 100       sleep 1       process = process+1     end   end end

This is the code I used to invoke this worker.

session[:make_view_job]=MiddleMan.new_worker(:class=>make_view_worker,       :args=>{:product_name=>@project_name, :user_name=>@user_name,               :version=>@project_version})

I have a feeling that you are mixing up syntax of BackgrounDRb across its varied releases.

For example, syntax for creating new workers is:

http://backgroundrb.rubyforge.org/rails/#new_worker

I know what wrong. I should use this code:

used_job_key = MiddleMan.new_worker(:worker => :foo_worker,\      :worker_key => "my_secret_job_key")

to get a worker. But after this, how can I invoke the worker with this key?

examples are right there in the docs. For example to invoke the worker:

MiddleMan.worker(:foo_worker,"my_secret_worker_key").async_do_foo()

MiddleMan.worker(:foo_worker,"my_secret_worker_key").async_do_foo()

thanks it works. but when I call this method I will get this error. I have started backgroundrb server.

Please read the API docs carefully, rather than getting spoon fed here on the list. These things are clearly mentioned on http://backgroundrb.rubyforge.org
