customizing java logging configuration file

[rsst]

I would like to redirect the log messages coming from different applications to different files, specifying the file names in the configuration file, instead of in my program itself. The configuration file should look some thing like this...


# For example, set the com.xyz.foo logger to only log SEVERE
# messages:
com.xyz.foo.level = SEVERE

com.xyz.foo.file = file1.log
com.xyz.abc.file = file2.log

Pl. suggest me a way

Using log4j, something like this, in a log4j.properties file on the classpath, would give you two unlimited length log files.

log4j.logger.com.xyz.foo=FATAL, A
log4j.logger.com.xyz.abc=FATAL, B

# Configure appender 
log4j.appender.A=org.apache.log4j.FileAppender
log4j.appender.A.File=LogFile1.log

log4j.appender.A.layout=org.apache.log4j.PatternLayout
log4j.appender.A.layout.ConversionPattern=%-4r [%t] %-5p %c %x - %m%n

log4j.appender.B=org.apache.log4j.FileAppender
log4j.appender.B.File=LogFile2.log

log4j.appender.B.layout=org.apache.log4j.PatternLayout
log4j.appender.B.layout.ConversionPattern=%-4r [%t] %-5p %c %x - %m%n

There is no 'severe' level in log4j, but I believe you can 'roll-your-own' custom levels.
