IMHO phoenix and the avalon framework are holding the server back
Yes, they do. but not everyone here thinks this way, AFAIU. But
maybe this has changed.
I found the avalon/pheonix stuff rather hard to understand. IMO if
it's kept it would be best as a layer on top of a container-
agnostic component layer.
i would like to be able to run james on the phoenix container but
don't want the server architecture to be determined by it. my
preference would be to replace the intrusive Avalon interfaces with
JSR-250 annotations. this would provide a natural path toward
smoother
integration with JEE containers whilst providing an easy route to
retain phoenix compatibility. if this sounds like an idea would
exploring, i'll open a JIRA with more details.
+1.
Maybe worth looking into at ACEU09's hackathon. WDYT?
I'll have a look at the JSR250 spec over the next days to be able
to comment.
Also note that something very like spring + osgi is coming to the
next osgi spec as rfc 124 blueprint service.
Also IIUC JavaEE6 is going to have a much more general dependency
injection framework, from what may be currently the web beans spec
proposal. I don't know any details on this.
Geronimo xbean has a bunch of libraries that make annotation
scraping and component creation pretty easy -- xbean-finder and
xbean-reflect.
I think that xbean is interesting stuff. I never seriously
considered it a container for James Server, because I wondered why
it is develop without a critical amount of public discussion and
more than just bare documentation. (You know, we have more than
enough trouble with a certain discontinued container dependency
already ;-) ) Hopefully I find the time to check again the state the
xbean project is in currently.
xbean is a bunch of closely focussed independent libraries that are
useful for building containers, it's not a container itself. The
closest to a container is xbean-spring which is a way to use custom
schemas adapted to your components with spring.
Xbean libraries are used in at least geronimo, openejb, servicemix,
and (at least xbean-spring) activemq and apacheds.
As far as discussion, my experience with xbean has pretty much been
that I look at the code and find that the design is really good and
often better than the approach I had in my head. After that I don't
have much to say.
