Well, Mike mentioned in his WW2 talk at TSS that we were doing it, so I
guess so :-)
Thanks Jason i got it, looks like my mind was
stuck with only one way to think about this ;)
I have played a bit with a nano container and i
really like it, is there a consensus about integrating it in WW2 yet
?
Regards
Chris

Think of them as services... your persistence manager might be a
good candidate. You could bind a Hibernate implementation, for instance,
into the persistence manager spot in the registry. It could declare that
it depends on a ConnectionProvider (another component) so it would be
provided one when it is instantiated. You could also have a ShoppingCart
component / service which depends on the PersistenceManager,
etc...
Refining a little bit my question, what
does make a good candidate for a component ? Obvious examples we see
everywhere is bridge component ( Trade component to query a trade
engine etc...) but beside this ? Many things can be done with
interceptors and you can always re use your business layer or part of it
in another applications, guess i dont get it :)

Hi everyone, while reading the topic
about nano/pico container, few questions keep coming to my mind,
what exactly is a component, which purpose does it have ? How exactly
is it different from an aspect in AOP ? How do you choose to code
something as a component rather than as a 'module' in your business
logic ?
Thanks in advance for any though you can
share on this topic.
