Karaf 4 Playground

Codebase structure

  • modules: Aggregates OSGi bundles.
    • api-interface-1: Exposes ResponderService and SingleInstanceResponder, interfaces to be referenced in consuming bundles.
    • api-impl-1: Implements interfaces from api-interface-1. Annotated with OSGi compendium @Component.
    • api-consumer-1: Implements a consumer of ResponderService interface. Referenced by @Reference(target = "(type=world)"....
    • api-consumer-2: Implements a consumer of ResponderService interface. Referenced by @Reference(target = "(type=hello)"....
    • api-consumer-blueprint: Implements a consumer being bootstrapped by blueprint, using a references pointing to SingleInstanceResponder.
  • assembly: Builds a custom Karaf 4 distribution using Karaf Maven plugin with <packaging>karaf-assembly</packaging>.
    • resources/etc: Contains .cfg files to initiate two instances of ResponderService. These configs carry a type field which is used for differentiating instances to be bound to consumers.
  • features: Aggregates OSGi features being build into custom Karaf 4 distribution.
    • feature-1: aggreates api-interface-1 and api-impl-1. This is a boot feature.
    • feature-2: aggreates api-consumer-1 and api-consumer-2. This is not a boot feature, its just installed.
