Lightbend Activator

Akka scheduler for Scala & Java

Activator will be EOL-ed on May 24, 2017.

We’re making it easier and simpler for developers to get started with Lightbend technologies. This unfortunately means that future releases of Play, Akka and Scala will no longer include Activator support, and Lightbend’s Activator server will be decommissioned by the end of 2017. Instead of supporting Activator to create and set up development projects, we'll be supporting standard Giter8 templates for sbt users and Maven archetypes for Maven users. So going forward,

To create new Lightbend projects

Instead of using the Activator command, make sure you have sbt 0.13.13 (or higher), and use the “sbt new” command, providing the name of the template. For example, “$ sbt new akka/hello-akka.g8”. You can find a list of templates here.

Also, as a convenience, the Lightbend Project Starter allows you to quickly create a variety of example projects that you just unzip and run.

To create new templates

If you want to create new templates, you can now do that in Giter8.

To migrate templates from Activator to Giter8

If you created Activator templates in the past, please consider migrating them to Giter8 with this simple process.

How to get "Akka scheduler for Scala & Java" on your computer

There are several ways to get this template.

Option 1: Choose akka-scheduler in the Lightbend Activator UI.

Already have Lightbend Activator (get it here)? Launch the UI then search for akka-scheduler in the list of templates.

Option 2: Download the akka-scheduler project as a zip archive

If you haven't installed Activator, you can get the code by downloading the template bundle for akka-scheduler.

  1. Download the Template Bundle for "Akka scheduler for Scala & Java"
  2. Extract the downloaded zip file to your system
  3. The bundle includes a small bootstrap script that can start Activator. To start Lightbend Activator's UI:

    In your File Explorer, navigate into the directory that the template was extracted to, right-click on the file named "activator.bat", then select "Open", and if prompted with a warning, click to continue:

    Or from a command line:

     C:\Users\typesafe\akka-scheduler> activator ui 
    This will start Lightbend Activator and open this template in your browser.

Option 3: Create a akka-scheduler project from the command line

If you have Lightbend Activator, use its command line mode to create a new project from this template. Type activator new PROJECTNAME akka-scheduler on the command line.

Option 4: View the template source

The creator of this template maintains it at https://github.com/rklick-solutions/akka-scheduler.

Option 5: Preview the tutorial below

We've included the text of this template's tutorial below, but it may work better if you view it inside Activator on your computer. Activator tutorials are often designed to be interactive.

Schedule sending of messages to actors and execution of tasks

The approach using schedule is one good approach, although there is a potential for the messages to queue up if the work done on schedule is so great that it might take longer than the scheduled interval. If you want the interval to occur between the end of one iteration and the beginning of the next, then use scheduleOnce.

Create project using activator command

If you have Typesafe Activator, use its command line mode to create a new project from this template.

Type activator new PROJECTNAME akka-scheduler on the command line.

Execute Scala Scheduler
$ ./activator "project akka-scala" run
Execute Java Scheduler
$ ./activator "project akka-java" run
