Re: Custom Appender

I'm unclear how what you're asking for isn't handled by
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.

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.
