Hi,
You can send an akka.actor.Identify("hello") and the actor will reply with
akka.actor.ActorIdentity("hello", Some(actorRef)) message, if it exists.
If it doesn't exist the reply will be akka.actor.ActorIdentity("hello",
None), but this message (as all messages) can be lost and then you will not
receive any reply, and then you can retry it.
You need an actor to handle the reply, which you might not have in your
Play application. Then you can use ask instead, and act on the
Future[ActorIdentity].
Cheers,
Patrik
