    <p>I got a little problem. I just moved the client-server-communication of my current project from remote Scala Actors to remote Akka Actors.</p> <p>Everything worked fine while testing on my local machine but once I tried to run the code with the client and server at different machines the client can't reach the server anymore (I get a <code>java.nio.channels.NotYetConnectedException</code>). I double and tripple checked the ip and port being used. It's the same host data I used in the code with the Scala actors (which by the way still work. So apparently nothing changed at the firewall settings and server is technically reachable)</p> <p>Here are the important parts of the code (which I mostly copy pasted from akkas homepage):</p> <p>On the server actor</p> <pre><code>import akka.actor.Actor._ import akka.actor.{Actor, ActorRef, Supervisor} override def preStart = { // I also tried the servers external ip here remote.start(host, 1357) // SERVER_SERVICE_NAME is a string constant in a trait that both server // and client extend // all actual work is refered to SessionActor remote.registerPerSession(SERVER_SERVICE_NAME, actorOf[SessionActor]) } </code></pre> <p>and on the client:</p> <pre><code>import akka.actor.Actor._ import akka.actor.{Actor, ActorRef, Supervisor} override def preStart = { // CLIENT_SERVICE_NAME is a string constant Actor.remote.start("localhost", 5678).register(CLIENT_SERVICE_NAME, self) // I also tried "Thread sleep 1000" here just in case // internalServer is a private var of the type Option[ActorRef] // host and serverPort are actually read from a propertiesfile. Guess this // doesn't matter. I checked them. internalServer = Some( remote.actorFor(SERVER_SERVICE_NAME, host, serverPort) ) // Again I tried "Thread sleep 1000" here. Didn't help neither internalServer foreach (server =&gt; { (server !! Ping) foreach (_ match { // !!! this is where the exception is thrown !!! case Pong =&gt; println("connected") case _ =&gt; println("something's fishy") }) }) } </code></pre> <p>I am using: Scala 2.8.1 (although I'm no sure whether the machines at my client are 2.8 or 2.8.1, I use the scala-library.jar from the akka distribution) Akka 1.0</p> <p>I know that you can't debugg my code her but I'd be very thankfull for any kind of hint or idea what might be going wrong here.</p> <p>P.S.: the Exception is thrown within a splitsecond after trying to send the <code>Ping</code>. So I didn't bother increasing the Timeout-time.</p>

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.
