File Appender in log4j
Hi,
Can you please tell me how can I configure file appender so that it
writes to 1 log file per data and have the old one stays?
Thank you.

That parameter only exists for RollingFileAppender. To the best of
my knowledge there isn't a way to do that in log4j, but since the
files should be closed, you are free to have a cron job to do that
maintenance.

I try it, but I get this error "
log4j:WARN No such property [maxBackupIndex] in
org.apache.log4j.DailyRollingFileAppender.
I put this line in the log4j properties file.
log4j.appender.ACCESS.MaxBackupIndex=7

I think you can set the MaxBackupIndex parameter like this:
log4j.appender.drfa.MaxBackupIndex=7

Alternatively, if you're looking for one log file per application launch, you
could have a look at http://permalink.gmane.org/gmane.comp.jakarta.log4j.user/14467

I guessing that you meant "1 log file per DAY". If that is your
request, you could use a DailyRollingFileAppender which would write
all log messages to a file which would be renamed after the day
changes. The configuration would looks something like:
log4j.rootLogger=DEBUG, drfa
log4j.appender.drfa=org.apache.log4j.DailyRollingFileAppender
log4j.appender.drfa.file=mylog.log
log4j.appender.drfa.Append=false
log4j.appender.drfa.layout=org.apache.log4j.PatternLayout
log4j.appender.drfa.layout.ConversionPattern=%m\n
Messages would be logged to mylog.log and after the day changes the
file would be close, renamed mylog.log.2006-11-21 and subsequent
logging would be captured in a new mylog.log file.
There has been some development of a MultiFileAppender that could
actually write the file in place and would not require renaming the
file, but that isn't working yet.
