Jruby Rails on Torquebox calling EJB services - model classes

Question

I'd like to play with Torquebox and have Rails (or e.g. Sinatra) as a frontend, but have all my services and business layer in EJB with CDI and JPA and all that stuff.

1) Can I have it all deployed as one application and use local calls for EJBs

2) If I have Rails, I can use models (no ActiveRecord) just to exchange data with frontend. How can I call EJB services with such models? I mean having:

def create
  user = User.new(params)
  userRepository = inject(Java::com.example.UserRepository)
  userRepository.create(user)  // this is java call
end

How can I pass User (jruby model to EJB call)? Or should I do

user = Java::com.example.User(params)

instead of plain ruby models.

Basically I'd like to have front in Ruby and the rest of machine in Java EE stack.

The TorqueBox integration tests have an app that does something similar, see:

https://github.com/torquebox/torquebox/tree/2x-dev/integration-tests/apps/rails3/twitter

It loads an ApplicationScoped bean from lib/ejb.jar, the source of which can be found at:

Hopefully that will get you pointed in the right direction.
