The default implementation of the SClientIntegrationSpec class gives an error if we try to run the tests twice. (port already in use).

The default template from giter8 uses TestKit and BeforeAndAfterAll to cleanly close the test class after execution. Why not use those?

Hi, I've been reading the book on Safari Online. It's fantastic!
In section "Creating an actor" of Chapter 2, seems "variable lengle list" in the first paragraph of "Props" should be "variable length list".

Thanks.

I'm trying to run your code without activator. It works if I run it with sbt publishLocal and sbt run as downloaded. When I copy your build.sbt and src/ directory to another project akka remoting doesn't start. I've also added the activator and activator-launch-1.2.10.jar file but that makes no difference.

What else do I need to get this to work without activator?

Hey, I just went through this and for the code example on page 112:

public void postStart() {
    self().ask(new Connect(), null);
}

override def postStart = self ! connect

Shouldn't it be:

public void preStart() {
    self().tell(new Connect(), null);
}

override def preStart = self ! connect

I don't find postStart as an akka method that we can override. And the java code should use tell instead of ask.
Is it a typo or am I missing anything?

Thanks

Hi,
In the chapter 2, AkkademyDb class, we have two different syntaxes for the same pattern (sending a failure message to the sender)

case None => sender() ! Status.Failure(new KeyNotFoundException(key))
and
case o => Status.Failure(new ClassNotFoundException)

Why do we user sender() ! in the first example and not the second? Is there any difference? Does it matter?
