Log4j output files

[Fisher Daniel]

Hi all,
I have an application that consists of some business modules.
And I am going to use log4j to log every incoming request to that modules.
I want every module have own log files so I can trace every request in each module.

I try to setting the log4j.properties file like this

  
log4j.rootLogger=debug, stdout, R1, R2
 
######### Console
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
 
######### First file
log4j.appender.R1=org.apache.log4j.RollingFileAppender
log4j.appender.R1.File=example_1.log
 
log4j.appender.R1.MaxFileSize=100KB
# Keep one backup file
log4j.appender.R1.MaxBackupIndex=1
 
log4j.appender.R1.layout=org.apache.log4j.PatternLayout
log4j.appender.R1.layout.ConversionPattern=%p %t %c - %m%n
 
######### Second file
log4j.appender.R2=org.apache.log4j.RollingFileAppender
log4j.appender.R2.File=example_2.log
 
log4j.appender.R2.MaxFileSize=100KB
# Keep one backup file
log4j.appender.R2.MaxBackupIndex=1
 
log4j.appender.R2.layout=org.apache.log4j.PatternLayout
log4j.appender.R2.layout.ConversionPattern=%p %t %c - %m%n
 

Example module A using R1 and module B using R2.
How can I use that inside my classes in each module?

Thanks
daniel

You will have to add following

log4j.category.Module1=DEBUG,R1

log4j.category.Module2=DEBUG,R2

Then you can do following to check logging

Category cat = Category.getInstance(yourClassFromModule1.class.getName());
cat.info("Opened log file");

hey Shreeya,

Can we do something like that using Logger class since Category is deprecated in the version tht i m using (log4j-1.2.8)

Thanks,
