Having a separated handler for POJOs and other for Avalon would kill us if the user'd like to code his components using both of them. Ok, so now we can make the AvalonHandler extends PojoHandler.
better use delegation.
That's fine. Now we'd like to write a InterceptorHandler that gives components interceptors/aop capabilities. We should extend what?
what is interceptor capability? If you want to add interceptors you add interceptors.
Creating a chain of handler can solve this situation, or composing them. But this can be a bit harsh to configure, don't you think?
Not really. Can use a builder pattern for example.
handler = myHandlerBuilder .newHandler( MyBasicHandlerImplementation.class ) .addInterceptor( MyAdvice.class ) .enableConstructorDependencyInjection() .enableAvalon() .enableLifecycleExtension( MyLifecycleExtension.class ) .create();
or whatever. Have all the composition is behind the scenes (which is also not /that/ difficult to implement well).
Speaking of thinking, what do you guys think? ;-)

googling for '"Leo Simons" container' or something like that should pop up a whole lot of thoughts from a while back ;)
(Btw I'm not trying to push this model here, just asking for opinions.)
hehehe :D
You (and Leo Sutic :-D ) are not so far from what in my current thinking is the best architecture. Berin is a few steps ahead of me; Pico nor the current fortress are actually /that/ different when you get down to it.
In fact, I decided pico was "good enough" in terms of architecture and "a whole lot better" in terms of community and maturity so I rm -Rfed my own container experiments and joined Paul 'n Aslak 'n friends. /If/ a from-scratch-rewrite of fortress is a good idea (I'm not so sure that it is), I think it would be a good idea to start with pico and build on that.
