Well, actually, under Tomcat, I wrote an InitContextListener which automagically figures out where the current webapp exists and sets a system property which is referenced in log4j.xml and, viola!, the log files are placed in WEB-INF/logs of the current application no matter where it exists and without ever hardcoding the actual path. Of course, this assumes you actually have write access to your webapp which is not guaranteed by the servlet spec. In that case, your file appender will not work since it won't have a valid location to write to.
See the InitContextListener in the log4j-sandbox. Instructions are in the javadoc. See info and links here...

G'day,
Ummmm, so basically then it is not possible to define a directory path in the log4j.xml properties file so that log files are placed relative to the web apps root directory? Or for that matter relative to any known anchor point like the server root directory?
A problem we have is that we deploy .war files by sending the package to the server gods who then drop it into the webapps directory. Alas we don't have the rights to deploy directly to the server environment and tools like ANT whilst are good at building a distributable archive they do not quite make the grade when resolving tokens in a dynamic style of deployment. Another issue we have is that most of the development work is done on a Windows based machine and the production servers are hosted on a flavor of Unix. Hard coding a directory path like "C:\..\" may work when doing the dev work under Windows but just don't kind of cut it on a Unix file system when it comes time to deployment.
BTW, the last time I looked me was male so I'll opt out for king!

Howdy, I suppose Adrian could be a woman's name as well, so you're right ;)
