Log4j not writing to FileAppender

[kwame Iwegbue]

I'm just learning to use Log4j and I've searched the Log4j site and mailing lists before posting this question here.

I have this properties file:

   log4j.rootLogger=debug, stdout, R
 
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
 
# Pattern to output the caller's file name and line number.
log4j.appender.stdout.layout.ConversionPattern=%5p [%t] (%F:%L) - %m%n
 
log4j.appender.R=org.apache.log4j.RollingFileAppender
log4j.appender.R.File=log_output.log
 
log4j.appender.R.MaxFileSize=100KB
# Keep one backup file
log4j.appender.R.MaxBackupIndex=1
 
log4j.appender.R.layout=org.apache.log4j.PatternLayout
log4j.appender.R.layout.ConversionPattern=%p %t %c - %m%n 

It is writing to ConsoleAppender quite alright, but not to the RollingFileAppender. I've tried placing the file 'log_output.log' in src, in /main-folder, and even WEB-INF/classes.

Can someone help?

why do not you try with the full path of the file 'log_output.log' .
like c:\test\log_output.log in the log4j.properties.
