Thanks a lot for the reply, it did help *a lot* :-). I still have a few
concerns, though they're just things that surprise me rather than real

I guess the real problem here (apart from my being unable to find the proper
class by myself) might be that absolutely no error message regarding the
incorrect syntax of the expected property file is displayed when trying to
load the XML file using the PropertyConfigurator, even in the debug output.
There not being such an error message made me think there was no problem on
this front. That might be a thing they might want to improve in the next

I'd have thought having the level value of root set to "fatal" would prevent
"info" messages from being displayed by the root logger, even with the same
appender? Or is this not taken into account when displaying messages coming
from child loggers? 

anyway, thanks again, now it's gonna work like a charm :-)
