We have a modular application where modules have their own log4j logs (i.e. communication log and error log). The appenders and categories for these are all configured in the core log4j XML, but not all modules are always installed.
The DailyRollingFileAppender creates its file regardless of use and that exposes the full set of modules a...

I use log4j and would like to route the output of certain Loggers to specific files.
I already have multiple appenders in place. Now, to make debugging easier, I want to tell log4j that the output generated by a specific class (e.g. foo.bar.Baz) should be written to a specific log file.
Can this be done?

Hi ,

It seems that by default, log4j looks into the root of a class folder, I can say that using the debug log4j functionality and running my application from the IDE.
However, I don't have any class folder in my jar anymore. And the log4j....
I have recently inherited a J2EE Struts web app that was written back in 2002. There is no logging in the application other than the odd System.out.println().
I have added log4j logging so that I can write out some info to the console, but I'm concerned on how best to approach this. Any suggestions, tips, best practices would be welcome...
