Hi,
Over at FOP, several (4) users have recently raised concerns with
FOP's adoption of Avalon and LogKit. The most valid complaint is by those
who had embedded FOP into applications that use Log4J and now have two
different logs. I remember the proposal to make a single Avalon interface
that either Log4J or LogKit could be plugged into interchangeably, but now
that Avalon 4.0 final is out, I wanted to raise the issue again. Also,
there's an alternative approach to the proposal that might have some good
ideas:
