the latter is necessary because of broken DNS requirements which make apex domains brittle (since they must resolve to an A record with a single IP)

The Obligatory Hello World
|
||
##########################
|
||
|
||
The actor based version of the tough problem of printing a
|
||
well-known greeting to the console is introduced in a `Typesafe Activator <http://www.typesafe.com/platform/getstarted>`_
|
||
tutorial named `Akka Main in Java <http://www.typesafe.com/activator/template/akka-sample-main-java>`_.
|
||
|
||
The tutorial illustrates the generic launcher class :class:`akka.Main` which expects only
|
||
one command line argument: the class name of the application’s main actor. This
|
||
main method will then create the infrastructure needed for running the actors,
|
||
start the given main actor and arrange for the whole application to shut down
|
||
once the main actor terminates.
|
||
|
||
There is also another `Typesafe Activator <http://www.typesafe.com/platform/getstarted>`_
|
||
tutorial in the same problem domain that is named `Hello Akka! <http://www.typesafe.com/activator/template/hello-akka>`_.
|
||
It describes the basics of Akka in more depth.
