Subject Re: XML Config
Date Mon, 10 Sep 2012 13:20:24 GMT
Generally speaking, I think it would be good to have a mechanism for 
configuring beans that does not require re-compilation - may be of 
limited use in greenfield applications, but above all with 
brownfield/legacy code. In fairness, for the latter one could use 
producers and such, but it may still be a PITA in some cases.

Now, the key here IMO would be to have a scriptable (no recompilation) 
and toolable DSL outside the annotation system. It so happens that of 
all the options, XML is IMO the most common and better understood by the 
average developer. If we manage to define a proper intermediate model 
for this mechanism, then there could be plenty of other options (yaml, 
or even Groovy or Ruby if one so wishes) to add on later.
