Howdy,
"What are make files" is an opening for a long philosophical debate
I'm not going to go into ;) (Except to say one thing: Ant!)
The DailyRollingFileAppender always writes to one file, then rolls it
over. The file it writes to doesn't have a timestamp, only the past
files do. And you have to keep your JVM running through the rollover
period for it to happen.
So for example, let's say you have a DailyRollingFileAppender with
an hourly rollover pattern, file named "foo.log." When you start
logging, foo.log will be created and will be written to. If the JVM
is running for over an hour, the file will be rolled over to
foo.log.[date_pattern], a new foo.log will be created, and log4j will
write to foo.log. The earlier file is closed and never opened again.
Of course, if you stop the JVM or never log to the file before the
rollover occurs, it won't occur, so the next time you start the JVM
you'll be writing into the old file ;)
I hope this helps,
Yoav
