Hey Guys,
It looks like James (Apache Mail Server) has done a
lot of research on XBean and OSGi already.
Hi Ole, I'm a James PMC member,
Well, we did not really much research. One fine day Alan Cabrera
suggested us to move to maven2+xbean: someone liked the idea, someone
didn't.
At that time XBean was at an early stage and spring 2 was not out yet (I
say this because I'm under the impression that XBean changed enough with
the introduction of spring 2, but I may be wrong).
So we never really evaluated XBean seriously. The same apply to OSGi.
The only real/concrete step we did has been some experimentation with
Spring2.
It sounds like they are favoring OSGi over XBean due
in part to it being standardized through JCP. It also
sounds like there is an XBean facade for OSGi.
Maybe this is "old news": now I think the key is that XBean runs on
spring2 and there is a promising spring-osgi support.
It is indeed true that many JAMES PMC committers expressed favourable
opinions against OSGi (nothing more than this).
Here's a link to the James thread, starting where the
discussion gets goooood.

Incidentally - Since they seems to be doing a lot of
work around this already, I think it would make sense
to combine our efforts with respect to Alex's list
below.
I just read this article and I liked it very much:
http://www.eclipsezone.com/articles/extensions-vs-services/
This increased my believing that spring-osgi is probably the way to go.
I would like to understand what XBean provides on top of this or what
the are really doing but I found it difficult to understand what is the
XBean roadmap from their website/jira.
Unfortunately we didn't do any work. Btw I'm really interested in this
and in my TODO list I have "Understand XBean<->SpringOSGi relationship".
