How to designate a thread pool for actors

Question

I have an existing java/scala application using a global thread pool. I would like to start using actors in the project but would like everything in the app using the same pool.

I know I can set the maximum number of threads that actors use but would prefer sharing the thread pool. Is this necessary/reasonable, and is it possible to designate the actor's thread pool?

If it is not possible/recommended, are there any rules of thumb when integrating actors in apps that are already using threads?

Thanks.

I believe you can do something like this:

trait MyActor extends Actor {
  val pool = ... // git yer thread pool here
  override def scheduler = new SchedulerAdapter {
    def execute(block: => Unit) =
      pool.execute(new Runnable {
        def run() { block }
      })
  }
}
