アプリケーションを play-2.0.2 に更新しています。

Akka リモート アクターのデプロイ時に問題が発生しました。

[error] play - Cannot invoke the action, eventually got an error: Thrown(akka.pattern.AskTimeoutException: Timed out)

アプリケーションの起動時に次のコードを呼び出す場合:

ActorSystem system = Akka.system();

Address addr = new Address("akka", "application");
defaultInstance = system.actorOf(new Props(TheActor.class).withDeploy(new Deploy(new RemoteScope(addr))), "theActor");

この構成が application.conf の場合:

akka {
  actor {
    provider = "akka.remote.RemoteActorRefProvider"
  }
  remote {
    transport = "akka.remote.netty.NettyRemoteTransport"
    netty {
      hostname = "127.0.0.1"
      port = 2552
    }
 }
}

play-2.0.1 でも同じ設定で問題なく動作します。

play-2.0.2 で動作するように構成を変更する必要はありますか?

ありがとうございました。

たぶんこれを試してみてください：akkaのドキュメントから、ポートを0に設定して、自動的に選択されたポートを使用できます。

akka {
  actor {
    provider = "akka.remote.RemoteActorRefProvider"
  }
  remote {
    transport = "akka.remote.netty.NettyRemoteTransport"
    netty {
      hostname = "127.0.0.1"
      port = 0
    }
 }
}
