How to log statements using log4j in file and console with different log levels?

[Vaman Kulkarni]

Hi all,

I am using log4j for logging in my application. My requirement is to log DEBUG statements in a log file and INFO statements in console.
Here is my sample log4j.properties.

  
log4j.rootLogger=debug, fileout
log4j.logger.com.ptc.v1tool=info, stdout

# Console appender configuration
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
# Pattern to output the caller's file name and line number.
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{HH:mm:ss} %5p %5M.%C - %m%n

log4j.appender.fileout=org.apache.log4j.RollingFileAppender
log4j.appender.fileout.File=./applog.log
log4j.appender.fileout.MaxFileSize=500KB
# Keep one backup file
log4j.appender.fileout.MaxBackupIndex=1
# Rolling File Appender layout
log4j.appender.fileout.layout=org.apache.log4j.PatternLayout
log4j.appender.fileout.layout.ConversionPattern=%d{HH:mm:ss} %5p %5M.%C - %m%n  

In above file, I set rootLogger to log DEBUG statements in a fileAppender and another logger "com.ptc.v1tool" to log INFO statements in console.
But the log file contains same entries as that in console i.e. log file contains only INFO logs

Can anyone suggest me how to accomplish my requirement?

Thanks.

Varun,

I would suggest using an log4j.xml file. There is an excellent tutorial on logging at http://www.laliluna.de/log4j-tutorial.html. This tutorial will walk you thru all of the steps.
