Custom Appender
Hi,
I am trying to see if I can leverage log4js nice feature of being able to do book keeping of log files and their sizes (e.g RollingFileAppender). I have two files which are backed up everytime a process runs. I only want to maintain a certain amount of backup info. From those with experience would it be worth trying to extend one of the existing Appenders in log4j to do this, or is a manual solution (rolling my own check and verify) the better way to go. I am already using log4j in this app so it would be nice if I could piggy back on it for this functionality.

Thanks. Yes I realized a much simpler solution was just get all the text from my file into a StringBuffer and input one long string into a logger whose appender was a rolling file appender. Seems to work fine although probably not the most efficient way. Hopefully there are no message length constraints for loggers.

RollingFileAppender, but all of the major appenders are pretty easy to
customize. In your log4j.properties/xml file you'd just specify your
new class instead of the standard one.
