log4j

How do I get log4j to pick up a properties file.

I'm writing a Java desktop app which I want to use log4j. In my main method if have this:

   PropertyConfigurator.configure("log4j.properties");

The log4j.properties file sits in the same directory when I open the Jar.

Yet I get this error:

log4j:ERROR Could not read configuration file [log4j.properties]. java.io.FileNotFoundException: log4j.properties (The system cannot find the file specified)

What am I doing wrong?

I noticed however, that writing a regular .properties file in the style of foo=bar fu=baz also works. This would mean a lot less typing (and maybe easier to read and more efficient as well). So what… >>> More
