Hello World Sample
public interface Hello extends Actor
{
Task<String> sayHello(String greeting);
}
public class HelloActor extends AbstractActor implements Hello
{
public Task<String> sayHello(String greeting)
{
getLogger().info("Received: " + greeting);
return Task.fromValue("You said: '" + greeting + "', I say: Hello from " + runtimeIdentity() + " !");
}
}
Hello helloActor = Actor.getReference(Hello.class, "0");
helloActor.sayHello("Hello!").join();
Building

the Hello Actor active.
Type a message in the command line and find which node
has the actor.

Stop the nodes with ctrl+d
Linux
Start each node with:
