Well, Jigsaw has is own way of doing filtering. There are two filtering
scheme, one for the client (proxy for example) and one for the server.

The one you want to use is the server-side filter.
Basically, there is an ingoing filter and an outgoing filter.
If the ingoing filter returns a reply, the processing is stopped (see
GenericAuthFilter).
Note also that filter can be aggregated, on the same protocol frame, or
inherited from the protocol frame of the parent resource (during the
lookup).
If you write your own filter you can do whatever you want in it, even call
a servlet if you want.
