Boy, I sure wish log4j had logdie().
On the plus side, not only did knowing Log4perl make learning log4j a breeze (other than configuration issues, which got into Java properties I didn't understand at first), but the Log4perl FAQ is a better reference for a lot of log4j questions than many log4j specific resources.
Thanks, Mike Schilli. You've done a lot to help me become both a better Perl programmer and a better Java programmer. And your name always turns out to be on a much-needed module when I discover it. If there's an unsung Perl hero award, I'd nominate you for it.
