Different appenders for different loggers?

[Steve Kuo <st...@yahoo.com>]

Here's what I'm trying to do. Use one appender for a
particular logger (say x.y.z), and another default
appender for everything else.

The default appender is easy:
log4j.rootLogger=ERROR, logFile
log4j.appender.logFile=org.apache.log4j.RollingFileAppender
log4j.appender.logFile.MaxFileSize=1MB
and so on..

What I can't figure out is how to setup an appender
for a particular logger instance?

Thanks, Steve

log4j.<loggerName>=<level> \
|INHERITED| NULL,<appenderName>,<appenderName>...

are my notes. so for logger x.y.z it might be

log4j.x.y.z=DEBUG, a1

where a1 is defined as

log4j.appender.A1=<full appender class Name>
e.g.

log4j.appender.A1=org.apache.log4j.FileAppender

I think that's right.

But making slow progress.
