Yeah, hence the term, i get that. np.

Yes, got something like that. I'm ok there, minus the m-g nomenclature.

Yeah... so every object gets my config bean. That's what this whole
post is complaining about.

Yeah, i mean, that's exactly what I'm doing. I've got a 'thing
manager' that spits out, in this case, blog entries. I guess the
difference is I should have it spit out _all_ my objects, including
the blog entry singleton... well, except there's a different config
bean for each blog. So I shoul come up with some sort of lazy loading
thing (or, i know, use someone else's). That's cool i guess. Cool
enough. So that way it somewhat automates the passing of my static
final app vars. ok, i can dig it.
So the singleton pattern... I know i should find some reading
material... The idea is, it just makes sure everything that comes out
of it has an instance of the config bean? Are there any other
advantages?
