I suspect the challenge isn’t going to be to get Drools itself running in Karaf, but Drools running AND wired to all the injected services and everything needed for the custom coded rule classes themselves.
I suspect you may need an OSGi-aware wrapper class that looks for the things you need and then wires up the drools engine. Possibly using a ServiceTracker and/or BundleTracker.
