It is not a secret …
I like OSGi and Scala … and therefore it was only a question of time until I started to wonder, if there is anything that would prevent me from using OSGi from/with Scala. The short answer and the good news is … nothing.
I just checked in my port of the original Apache Felix Tutorial to Scala. As mentioned in the README I do not want to claim that this boilerplate code, but it is a working development environment that you can use as a starting point for your own experiments.
