Have you tried the following?
(in log4j 1.1.x or log4j 1.2) if(!condition) { Category cat = Category.getInstance("net.winward"); cat.setPriority(Priority.FATAL); } (in log4j 1.2 only) if(!condition) { Logger logger = Logger.getLogger("net.winward"); logger.setLogger(Level.OFF); } Hope this helps, Ceki At 16:42 13.03.2002 -0700, you wrote: >Hi all; > >I have a library that I ship to people as a jar.
