    <p>For learning purposes I'm trying to implement a simple play application that gets data from a remote actor. The code for the actor is as follows:</p> <pre><code>import akka.actor.{Props, ActorSystem, Actor} class NumbersServer extends Actor { var number = 0 protected def receive = { case 'next =&gt; { number += 1 number } case 'reset =&gt; number = 0 case 'exit =&gt; context.stop(self) case 'get =&gt; sender ! number } } object Server { def main(args: Array[String]) { val system = ActorSystem("ServerSystem") val server = system.actorOf(Props[NumbersServer], "server") } } </code></pre> <p>I package it into a jar and start it from the command line. If I try to send messages to this actor from a Scala console opened from another window, all works fine. Now I want to get the actor from the Play framework. In the <code>Application</code> object I define the following method:</p> <pre><code>def numbers = Action { Ok(views.html.numbers(Client.actor.path.name)) } </code></pre> <p>Then in the <code>models</code> package I define the Client object:</p> <pre><code>object Client { import play.api.Play.current val actor = Akka.system.actorFor("akka://ServerSystem@127.0.0.1:2552/user/server") } </code></pre> <p>The <code>numbers.html.scala</code> file:</p> <pre><code>@(message: String) @main("Header") { &lt;h1&gt;@message&lt;/h1&gt; } </code></pre> <p>So I expect that when I go to <code>127.0.0.1:9000/numbers</code>, I'd get a page with the path to the server actor. Instead of this, I get <code>&lt;h1&gt;deadLetters&lt;/h1&gt;</code>. What do I do wrong and how this should be done correctly?</p>

    1. COHave you've enabled remoting on both ends?

    2. CO@ViktorKlang : I tried to enable remoting in play in a way analogous to plain akka, but there is no akka-remote package, so I just got `java.lang.ClassNotFoundException: akka.remote.RemoteActorRefProvider` and not sure what else to do.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
