A long time ago SolarNode development switched from a traditional style Java application to a modular OSGi based one. One of the reasons for the switch was the premise of allowing users to easily download and use SolarNode modules without having to restart the SolarNode application. In OSGi installing, starting, stopping, and uninstalling modules (called bundles in OSGi) is fairly trivial. What SolarNode has lacked, however, was any friendly UI to allow users to browse the available modules and install the ones they want.
Finally that is about to change. The first step to enabling this feature was the deployment of a SolarNetwork-hosted software repository. There are a few open source packages out there, I ended up using Apache Archiva. Now SolarNetwork has a Maven-compatible online software repository to host its own modules, and the build infrastructure has been updated to easily publish modules as they are developed.
The next step was to make use of the OSGi Bundle Repository (OBR) developed as part of Apache Felix. OBR provides a way to resolve OSGi bundles along with their dependencies. Unfortunately, Archiva does not publish OBR metadata so I turned to another Apache project, Karaf Cave. Cave can act as a OBR proxy to a Maven repository, in which case it scans the Maven repository and generates OBR metadata files from which the OBR resource URLs point back to the artifacts in the Maven repository.

The final step was to develop some SolarNode bundles to enable configuring OBR URLs and a UI to allow users to browse the available software and install or remove individual modules. You can see the result of this work in the following demonstration:

Owning an electric vehicle (EV) can be greatly simplified with the right preparation. A Checklist for EV owners highlights essential tools and practices, like reliable charging equipment, knowing charging locations, and tracking range. These factors are important for maximizing EV efficiency and avoiding potential issues. Additionally, EV drivers should consider investing in protective accessories to extend vehicle life. Planning with these essentials in mind can enhance the EV driving experience, making it smoother and more enjoyable.
