[confluence]

Using Scala with Sling Page added by Michael Dürig Using Scala with Sling Sling supports the Scala programming language version 2.7.7 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. 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 Scala Script Engine bundle. Goto /contrib/scripting/scala/script and type mvn org.apache.sling:maven-sling-plugin:install. Install the Apache Sling Scala Scripting Configuration bundle. Goto /contrib/scripting/scala/config and type mvn org.apache.sling:maven-sling-plugin:install. 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. 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. The hello world application is then available at http://localhost:8080/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. The form application is the available at http://localhost:8080/content/forum.html?sling:authRequestLogin=true. When prompted for credentials use admin/admin. Configuration The Scala scripting bundle is configurable through the Apache Felix Web Management Console (PID: org.apache.sling.scripting.scala.config.SlingSettingsProvider). Scala compiler options. Scala compiler settings as documented by scalac -help. Default is blank. Compiler output directory. Output directory for files generated by the Scala compiler. Default is /var/classes.
