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)

Microkernel
|
|
==================
|
|
|
|
The purpose of the Akka Microkernel is to offer a bundling mechanism so that you can distribute
|
|
an Akka application as a single payload, without the need to run in a Java Application Server or manually
|
|
having to create a launcher script.
|
|
|
|
The Akka Microkernel is included in the Akka download found at `downloads`_.
|
|
|
|
.. _downloads: http://akka.io/downloads
|
|
|
|
To run an application with the microkernel you need to create a Bootable class
|
|
that handles the startup and shutdown the application. An example is included below.
|
|
|
|
Put your application jar in the ``deploy`` directory and additional dependencies in the ``lib`` directory
|
|
to have them automatically loaded and placed on the classpath.
|
|
|
|
To start the kernel use the scripts in the ``bin`` directory, passing the boot
|
|
classes for your application.
|
|
|
|
The start script adds ``config`` directory first in the classpath, followed by ``lib/*``.
|
|
It runs java with main class ``akka.kernel.Main`` and the supplied Bootable class as
|
|
argument.
|
|
|
|
Example command (on a unix-based system):
|
|
|
|
.. code-block:: none
|
|
|
|
bin/akka sample.kernel.hello.HelloKernel
|
|
|
|
Use ``Ctrl-C`` to interrupt and exit the microkernel.
|
|
|
|
On a Windows machine you can also use the bin/akka.bat script.
|
|
|
|
The code for the Hello Kernel example (see the ``HelloKernel`` class for an example
|
|
of creating a Bootable):
|
|
|
|
.. includecode:: ../../../akka-samples/akka-sample-hello-kernel/src/main/java/sample/kernel/hello/java/HelloKernel.java
