Accessing Felix services from Jackrabbit classes

[Rory Douglas]

I want to write a facade AccessManager implementation that will delegate 
to a bundle-provided service.  The idea would be to register one or more 
bundles providing AccessManager implementations and be able to configure 
the paths and/or nodetypes that they control, though initially it will 
probably just delegate to one service (if available), and fallback to 
SimpleAccessManager logic if no AccessManager service is available.

Since the AccessManager implementation is instantiated by Jackrabbit 
directly (has no Bundle- or ComponentContext), how can I get a handle to 
the Felix framework to lookup/listen for services?  Would this even be 
advisable?

Regards,
Rory
