This has been bugging me for ages too.. Just committed a change. I think it's still an ERROR level, but doesn't log the full trace. The message though does contain the underlying exception message, so it's still pretty useful. Maybe a property on the appender if you DON'T want it to nag on error?
This could be controversial, but I'm in agreement with Jacob on this one. cheers, Paul Smith > -----Original Message----- > From: Jacob Kjome [mailto:[EMAIL PROTECTED] > Sent: Saturday, May 08, 2004 1:41 AM > To: Log4J Developers List > Subject: socketappender stacktrace, is it necessary? > > > > Hi everyone, > > I've been using Chainsaw2 and like it quite a bit (nice work > guys!).
