This method takes a filename. Since you've not provided a path to the
file, here, where did you put your file to ensure that it gets properly
loaded?

That depends on how you configure log4j. We simply do this:

new PropertyConfigurator();

...and put log4j.properties into the CLASSPATH by dropping it into the
WEB-INF/classes directory in our webapp.

What path are you using when you try to open the file? If you aren't
fully-specifying the path, then the path is relative. Relative to what?
Relative to the current working directory of the JVM process. What's the
CWD? It could be anything, though it tends to be either the CWD of the
parent process or CATALINA_BASE. You shouldn't have to worry about that,
though, because you should always fully-specify your file paths.

Better yet, load your file using the ClassLoader.
