Log4j configuration on a per context basis
Guys, how can I setup log4j with a context specific configuration file ?
In the past I used to put a global log4j configuration in the system
classpath for the tomcat, but that is no longer appropriate in my
current setup.

This is trivial if you only introduce log4j.jar in each web app.
If you share log4j.jar across web apps, then you have some
LoggerRepositorySelector coding ahead of you. This is easy enough via
JNDI context for cases where the contextual classloader is set for you
by Tomcat, but in other cases (e.g. JMX remote request threads) you
have to do such classloader setup yourself.
Our web app now supports a per context log4j even if log4j.jar is shared
-- in which case anything outside all the web apps goes into another
log4j context.
Note the log4j JMX MBeans don't support this sort of thing properly
(they have a hard-wired ObjectName location for starters), so you'll
have to write your own if you're interested in that aspect.

Thanks.
I figured that something like that would work, but for some non-related
issues, I rather not have a classes directory. Is there a way to have a
log4j configuration available to the web app w/o putting it in the
classes dir or in a jar file ? maybe someway to setup the context.xml
to point to a log4j configuration directly in WEB-INF ?

Hi,
remove any log4j.jar and log4j.properties from your global classpathes
(system classpath, common, shared).
Put a log4j.jar and log4j.properties in each WEB-INF/lib (jar) and
WEB-INF/classes (properties) with the correspondent config.
