Hi

Im new to OSGi and have played around with Pax Exam for a short while now.
Im trying to learn how to implement an annotation driven framework using
OSGi.

So I have created this silly little application where I have an api, impl
and client bundles. There is also an engine bundle that I want to use as the
framework to handle instance creation and proxy services.

The engine have a SynchronousBundleListener that listen for new bundles and
look for classes with the "Impl" annotation - and register new service
provider instances:
https://github.com/deephacks/osgi-demo/blob/master/engine/src/main/java/org/deephacks/osgi/engine/Activator.java
.

Two questions I havent managed to figure out:

1) I cannot cast the service and use it as a regular object with
JUnit4TestRunner from my test class:
https://github.com/deephacks/osgi-demo/blob/master/client/src/main/java/org/deephacks/osgi/client/Client.java
?

2) How do I inspect classes use the Reflection API from my framework that
isnt suppose to know anything about the api or impl bundles? The only way I
could get around this was using Strings like so:
"org.deephacks.osgi.Impl".equals(annotation.annotationType().getName() -
i.e. loadedClass.isAnnotationPresent(Impl.class) resolves to false.

I have published the source code on github:
https://github.com/deephacks/osgi-demo

Cheers,
-Kristoffer
