Sling supports the Scala programming language version 2.78.7 1 through optional modules located in /contrib/scripting/scala.

Installation

The following bundles are required for Scala support: scala-library, scala-compiler, Scala Script Engine, Apache Sling Scala Scripting Configuration. Note: In order to see the Scala scripting engine in action you can also use the Launchpad Contrib Testing module which comes with all necessary bundles (including the examples) pre-installed. See below.

Manual installation

• Start Sling

• Download the scala-library bundle and the scala-compiler bundle and install them using for example the Apache Felix Web Management Console.

...

• Install the Apache Sling Scala Scripting Configuration bundle. Goto /contrib/scripting/scala/config and type mvn org.apache.sling:maven-sling-plugin:install.

Using Launchpad Contrib Testing

• Goto /contrib/launchpad/testing and type mvn jetty:run -Pjcrinstall-tests to start Sling.

• Sling is now running at http://localhost:8888/. All required bundles and examples are pre-installed. See next section on how to access the examples. Remember to substitute the port number with 8888!

• See /contrib/launchpad/testing/README.txt for details.

Examples Applications

There are two example applications available in /contrib/scripting/scala/samples: A simple Hello World programm and a more advanced Forum application. The examples require the Apache Sling Sample Path Based Resource Type Provider bundle. So lets install this bundle first:

• Goto /samples/path-based-rtp and type mvn org.apache.sling:maven-sling-plugin:install-P autoInstallBundle clean install -Dsling.url=http://localhost:8888/system/console.

Now the examples themselves:

• Install the Scala for Sling Demo Application - Hello World bundle. Goto /contrib/scripting/scala/samples/hello-world and type mvn org.apache.sling:maven-sling-plugin:install-P autoInstallBundle clean install -Dsling.url=http://localhost:8888/system/console. The hello world application is then available at http://localhost:80808888/content/helloworld.html

• Install the Scala for Sling Demo Application - Forum bundle. Goto /contrib/scripting/scala/samples/forum and type mvn org.apache.sling:maven-sling-plugin:install-P autoInstallBundle clean install -Dsling.url=http://localhost:8888/system/console. The form application is the available at http://localhost:80808888/content/forum.html?sling:authRequestLogin=true. When prompted for credentials use admin/admin.
