So does the deafening silence that greeted this mean everyone is so
awed by this that they are left speechless? :-)
Seriously, does anyone have any comments on this? Does everyone
prefer the untyped spring style?
On a related note, I've seen a lot of Mutable****Configuration
classes in various spots and AFAICT their only purpose is to support
springs troubles with constructor dependency injection. I think
there's a way to use xbean-spring to make the xml style as below fit
into constructor dependency injection. Any interest in this, or does
everyone prefer what's happening now?
thanks

A while back there was some discussion of whether server.xml could
be made to be more semantically meaningful with less generic cruft,
and I suggested looking into xbean-spring. So, I spent a bit of
time on it and implemented this. See https://issues.apache.org/
jira/browse/DIRSERVER-984
This was pretty easy to do, after fixing some problems in xbean.
Basically all I did was add some javadoc "annotations" to tell
xbean which classes to look at and what type collections contain,
and change to the xbean application context from the plain spring one.
xbean generates a schema for the configurable objects so you can
consult the schema to see what can be configured. As you can see,
you can mix regular spring configuration and the xbean style in the
same server.xml.
There's a lot more customization possible, I basically did the
minimum possible to get it to work. Pretty much anything can have
a different name. The main ugliness I see is the handling of
properties that are lists (or sets) of strings.
So, at the risk of posting too large a message, here's the shiny
new server.xml (I removed some commented out bits) :
