Lightbend Activator

Salesforce Developer Workshop for 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.

Running the App

You can either run this app via the command line with activator ~run or from the Activator UI. Once the app is running open localhost:9000 in your browser. You should then see instructions for setting up Heroku Connect integration. Create a new app on Heroku with the Heroku Connect addon.

The REST Server

The conf/routes file defines all of the HTTP endpoints the Play Framework server handles. The REST service that fetches the Sessions from Salesforce and returns them as JSON is defined as:

GET    /contacts    controllers.Application.getSessions()
An HTTP GET request to /sessions invokes the getSessions method in the controllers.Application controller.

The Web UI

Requests to / are handled by the index method in the controllers.Application controller. The index method renders the index.scala.html server-side template.

The index template loads the app.js file. The JavaScript app calls the localhost:9000/sessions REST service.
