Windows 2000 SP4
Ruby 1.8.6
Rail 1.2.6
I''m trying to create a Rail application for our internal use to
provide a one stop access to services. I''m currently trying to get the
Server.status, Service.stop and Service.start to work through a model
in Rails. The Service.* functions work well through Ruby itself, but
seems to have problem through a Rails Model. I''ve been trying to
display the status of the MySQL service.
*** Model
require "win32/service"
class Servicectl
include Win32
attr_reader :state
def servicestatus(service_name, host_name)
@state = Service.status(service_name, host_name)
end
def servicestart(service_name, host_name)
Service.start(service_name, host_name)
end
def servicestop(service_name, host_name)
Service.stop(service_name, host_name)
end
end
*** Controller
class ServicectlController < ApplicationController
def show
service_state = Servicectl.new
service_state.servicestatus("MySQL",nil)
@status = service_state.state
end
end
*** Show View
<%= @status %>
The following error is posted to the development.log.

I have no idea why it is failing, I''m hoping someone might have a clue
for me.
For reference this is the working code which works well though Ruby
itself.
*** service.rb
require "win32/service"
class ServiceController
include Win32
attr_accessor :state
def status(service_name, host_name)
@state = Service.status(service_name, host_name)
end
def start(service_name, host_name)
Service.start(service_name, host_name)
end
def stop(service_name, host_name)
Service.stop(service_name, host_name)
end
end
*** Output:

Thanks for all your time,
