The trouble with properties is that they are not always that good at
expressing hierarchies of concepts (something XML does well), and if
you accidently spell a property wrong, that property silently
vanishes, leaving the end user staring at the config for hours trying
to figure out why it isn't working as expected.
JSon is hierarchical, even if it does not have nameSpace (which is
_bad_). So it's a pretty good alternative. Also one thing that make me
crazy s that with Spring, you have no clue about which bean is going to
be instanciated and we=hen. I mean, you have to put breakpoints all over
the code, when you want to debug the initialization. Something you don't
have to do when using a simple file you load. That is typically what
make me want to through my computer through my office or my appartement.
For instance, having such error messages is self-explanatory. Two
bullets in the head, and you send the bills to the parents... (more to
read at the end of the damn long Stack trace)

Insane, isn't it ?
PS: I have changed the principalDN property to accept a String, with no
luck. Spring+XBean is still fooled...
