Logging into clustered enviroment
Hi all, I am preparing myself for my first commercial application in clustered Tomcat environment. One of requests that I have is to allow exposing logs that happened on either TomcatA or TomcatB aggregated in single report. TomcatA and TomcatB are behind Apache Server and load balancing should be used. Until now I developed web applications just for single Tomcat, or in case that Load Balancing is requested no-one asked for such kind of aggregated report. My guess is that some kind of central repository for Logging should be used (TomcatA and TomcatB can access to that central repository and write thier logs there) but I am wondering what about permissions? What is TomcatA is writing to log and TomcatB should log to same log his stuff? Any experience about this matter? Can You point me out some inet address, blog, book ? Thanks in advance ? -- Aleksandar dipl. ing.

Re: Logging in Tomcat 5 (SysOut SysErr)
You will need some kind of logging framework to do this (e.g. Log4J).

Or even better would be to have 2 outputs: file and Windows console. I have tried to read Tomcat docs and got lost there. It mentions default catalina.log as output, but I don't have it. Nor logging.properties. Please, can someone give me short guide what I have to do to acomplish logging of system.err and system.out into the file(s)? I can not change the way applications log, apps log to system.out and doesn't use log4j.
