Dependency Issues Running a JRuby Thread

Question

I'm running on JRuby 1.6.7 with Rails 3.0.2. I have a few methods that call REST services.

It would be nice to execute them concurrently, so instead of each one taking 2 seconds to return totaling 6 seconds. I'll get the data back in about 2 seconds.

I can't use Fibers because the following calls use blocking io and cannot be modified so I cannot code them to work 'cooperatively'. I'm trying to use preemptive threads.

I have a simple call inside a thread as follows.

Thread.new do
  callrest1() 
end

Though I get the following error when this code executes inside the thread. I'm guessing it cannot find the correct files/classes because its in a new thread? Any ideas?

Expected /home/joe/ruby/analysis/app/models/dashboard/reports.rb to define Dashboard::Reports Rails.root: /home/joe/ruby/analysis
