Hi Akka users,
I've got a situation that's perplexing. It began with Akka 2.3.2 and i have
a Play 2.3-M1 attempting to connect to a Akka 2.3.2 actor (part of a
cluster named TrailingHammer) and it's not able to do so by throwing an
error message like the following:
play.api.Application$$anon$1: Execution exception[[MatchError:
Some(Failure(akka.actor.ActorNotFound: Actor not found for:
ActorSelection[Anchor(akka://application/deadLetters),
Path(/user/ShadowFrontend)])) (of class scala.Some)]]

Caused by: scala.MatchError: Some(Failure(akka.actor.ActorNotFound: Actor
not found for: ActorSelection[Anchor(akka://application/deadLetters),
Path(/user/ShadowFrontend)])) (of class scala.Some)
The code in the Play controller looks like this:
lazy val config = ConfigFactory.load("TrailingHammer")
lazy val notificationHost =
config.getString("bamboo.persistence.cluster.hostname")
lazy val notificationPort = config.getInt("bamboo.persistence.cluster.port")
lazy val notificationServiceName =
config.getString("bamboo.persistence.cluster.name")
implicit lazy val timeOut =
Timeout(config.getInt("bamboo.persistence.cluster.query.timeout") seconds)
val backend = Akka.system.actorSelection(RootActorPath(backendAddress) /
"user" / "ShadowFrontend")
This code is pretty idiomatic and i've used this successfully in Akka
[2.2.3] and wasn't too sure what's going on but the message on
*Path(/user/ShadowFrontend)* seems not to be catching the entire path which
should read like
"akka.tcp://[email protected]:2553/user/ShadowFrontend" and when i
plugged this string directly into the code and restarted all my services,
it gave me the following error message repeatedly indicating that somehow
the default actor for handling these faults have died as well. :
[INFO] [04/28/2014 15:36:58.380]

settings 'akka.log-dead-letters' and
'akka.log-dead-letters-during-shutdown'.

Any ideas guys ?
Thanks in advance!
