FW: Rotating catalina.out.
Howdy,
I just posted this to the tomcat-user mailing list. Over there, several
users now and in the past have asked for the catalina.out (tomcat's
default System.out / System.err destination) file to be rotated on a
regular basis. One person suggested using Apache's rotatelogs
(http://httpd.apache.org/docs-2.0/programs/rotatelogs.html) program to
accomplish this.
Tomcat already uses an internal mechanism to rollover other log files.
Log4j obviously has its own mechanism.
Now that we have a brand new rollover implementation in the works for
log4j 1.3, I was wondering if it makes sense to make a jakarta-commons
subproject out of it. See the message below for more details.
What do people think?

Hi Ceki,

Where did you hear that? Based on build of the recent CVS of Tomcat5,
commons-logging seems to be the logging API used. Log4j isn't even
included in common/lib. I don't see how it could be used directly if it
doesn't exist at runtime?
