Tomcat log rotation

Hi everyone

I am trying to rotate my tomcat logs....i am using log4j.properties file and it works fine for tomcat log messages.
But, the problem is with my app. (9 apps) which actually write to stdout (using consoleappender), this makes my stdout file
very large. so, i decided to rotate that stdout log file. I redirected stdout and stderr to a rollingfileappender but it did not work.

So, please does any one know if it is possible....can we use piped log just as apache server does?
please any solutions and suggestions are highly valuable....because i am kinda stuck here....

configuration:

tomcat 5.5
windows xp operating system.

please let me know if you need anymore info...

thank you in advance
