Log4j. appender. stdout. layout. conversionpattern = % d % P [% C]-<% m> % N

Log4j. appender. logfile = org. Apache. log4j. rollingfileappender
Log4j. appender. logfile. File =/home/trisberg/jakarta-tomcat-4.1.24/logs/springapp. Log
Log4j. appender. logfile. maxfilesize = 512kb
# Keep three backup files
