This looks very promising, whether I use it as is or as the basis to customize my appender further. Thank you.
I am still not clear as to how to submit the variables in the application (about the time I call Logger.info()) so that they arrive at the Appender's subAppend() method inside the LoggingEvent. Could you clarify? I hope it is not a dumb question. bruno -----Original Message----- From: Curt Arnold [mailto:[EMAIL PROTECTED] Sent: Friday, August 15, 2008 3:39 PM To: Log4J Users List Subject: Re: Passing log-time values to the Appender On Aug 15, 2008, at 3:19 PM, Bruno Melloni wrote: > I have an app that makes all Logger calls happen from a single class > and it uses a custom appender.

It is not released and is subject to substantial change, but you may want to look at it. See https://issues.apache.org/bugzilla/show_bug.cgi?id=45165 and search the mailing list archives for MultiFileAppender.
