Re: [jruby-user] Scala/Akka and JRuby

I use Akka extensively with jruby in
https://github.com/gamemachine/gamemachine.

It pretty much just works.  Only one thing I can think of that might throw
someone is that Akka now requires a factory for creating actors.  So you
have to jump through a couple of hoops to make that work when your factory
is ruby and your actors are ruby classes that inherit from UntypedActor.

My abstraction layer for actors is in server/lib/game_machine/actor.

If you look at builder.rb and factory.rb, and also in the java class
ActorFactory, you should see how it all fits together.   Basically I have a
java factory that is just a proxy to my ruby factory, and a java interface
to make it possible for java to call the create method on my ruby factory
instance.

Only reason I haven't broken out the actor abstractions into a separate gem
is I just haven't had people asking for it, but my project is fairly niche
and not really targeted at what most people use jruby for, so I'm unsure
how much of a demand there really is.
