Can I inject proxies in front of Blueprint services published by other bundles?

Question

We are using Karaf and a number of OSGI Blueprint services to implement a system.

Is it possible to make a \"BundleListener\" type

Answer 1

Although not implemented as a proxy, a Blueprint Interceptor might do what you want; you can intercept method invocations before or after the call to the original bean. I assume this is what you'd be doing with your proxy anyway. The Aries Blueprint implementation in Karaf should definitely support interceptors. However, I can't find good documentation or examples outside the Aries source itself, which makes this answer less useful than I'd hoped!
