Hi Ray, I'm not defining any additional manifest header if that's what you mean. I have no real control over the bundles I need to scan.
What I do is registering a BundleTracker that scans a bundle's classes if its wiring states it is importing the package of the annotation I'm looking for. (Can be seen here: https://github.com/Sandared/flow-osgi/blob/master/flow.osgi.integration/src/main/java/io/jatoms/flow/osgi/integration/FlowOsgiRouteTracker.java ) Those classes usually look something like this: @Route("") @Component(factory="fqcn") public class MyFancyUI extends Component { @Reference SomeService service; ... } So I'm looking into the wiring of the bundle if it has imported the package "com.vaadin.flow.router" . If so I then scan the bundle's classes for the @Route annotation (and @RouteAlias). Classes that have this annotation can later on be instantiated via ComponentFactory. Can I instantiate such a component with the Apache Aries approach and if so will its reference be injected? I'm not sure if this is done if I'm registering the instance just as a service.
