This presentation takes a closer look at deploying OSGi-based applications using OSGi Subsystems and OSGi Repositories. You will see how you to package multi-bundle applications as a subsystem, deploy them and use repositories to handle dependencies. A large part of the presentation is a demo that shows it all in action using open source technology.
Note that in the screenshots Apache Aries Subsystems Core is using a pre-release version. This bundle is now released under 1.1.0.
