Hi, The annotations in PlanetResource add OSGi properties and code that registers the class as adatable from a PlanetResource to a ValueMap. You need to do the same for CassandraResource. The contents of the ValueMap (backed by a Map), should be selected properties of the Cassandra row. (ie the names and values of the columns).
