Ok, what does 'TINA' mean :-) ???

I see your point, I'll play a bit more with the class loaders ( I'm using
log4j in common ). 

In JDK1.4 we don't have the option to move the logging in
the container loader :-), and at least log4j can be upgraded in common
at any time, not only when you upgrade the VM.

I'll try to get it in container. It should work, except the messages that
are displayed before the logger is set up ( where the 'default' of 
commons-logging will be used ).


What I'm worried about is setting up the per/context loggers and where 
they'll write. I assume webapps using log4j will provide their own 
configuration, but how do we mix this with the global settings ? And 
how do we deal with the sandbox.


Fortunately ( or not ) JDK1.4 logger doesn't seem to care about security,
so why should we worry ...

Ok, it'll be more painfull than I thought - but still we should do it,
it's a mess.

Long term I think o.a.t.u.log should be deprecated. I agree qlog is a nice 
( and quite efficient ) piece, so maybe it can be turned into a 
common-logging logger ( and so available to other apps ). 

The last thing we need is yet-another logging API ( o.a.t.u.log is 
probably older than most others, but that doesn't matter ).
