Where to place log4j.xml

Question

How can we specify were log4j has to look at when trying to find its xml configuration file ?

It seems that by default, log4j looks into the root of a class folder,

Answer 1

It finds the log4j.xml using the CLASSPATH. If log4j doesn't find any config file, it will send an error to the console. If you don't see any such error then it is likely that it is finding a config file which may not be the one you are editing. There is a command-line option to force Log4J to report the path of the config file it is using.

From http://wiki.apache.org/logging-log4j/Log4jConfigurationHelp

If you run with "-Dlog4j.debug" then log4j will print out info to standard output telling how it is trying to configure itself. Looking through that will tell you where it is looking for the config file.
