Subject Re: using a different log4j.properties file per classes directory
Date Wed, 15 Jul 2009 01:31:44 GMT
Got it working exactly as I want.  thanks everyone.  I included my
.properties file below for reference

log4j.rootLogger=INFO, R
log4j.appender.R=org.apache.log4j.RollingFileAppender
log4j.appender.R.File=${catalina.home}/logs/tomcat.log
log4j.appender.R.MaxFileSize=100MB
log4j.appender.R.MaxBackupIndex=50
log4j.appender.R.layout=org.apache.log4j.PatternLayout
log4j.appender.R.layout.ConversionPattern=%-5p: %d{MM-dd@HH:mm:ss} %t %c -
%m%n

log4j.additivity.com.tabs=false
log4j.logger.com.tabs=DEBUG, T
log4j.appender.T=org.apache.log4j.RollingFileAppender
log4j.appender.T.File=${catalina.home}/logs/tabs.log
log4j.appender.T.MaxFileSize=25MB
log4j.appender.T.MaxBackupIndex=50
log4j.appender.T.layout=org.apache.log4j.PatternLayout
log4j.appender.T.layout.ConversionPattern=%-5p: %d{MM-dd@HH:mm:ss} %t %c -
%m%n
