Log4J - email notification of production errors

There are a couple of things I try to do before I sit down to write Java code for even the smallest project (cause they always grow). One is creating an ant build script and the other is creating a log4j configuration file and adding log4j to my library path. I used to sprinkle System.out.println's throughout my code and now I've gotten in the habit of using the logging library.

I hadn't used the SMTPAppender, but recent issues with production code got me thinking about it so I'd have a heads up before users starting yelling. Below is the log4j.properties file that's worked well so far. The code is all custom so I have total control of all log.error and log.fatal statements, so when I get an email I know exactly what the issues is. Wouldn't be possible if I still used System.out.

Just a note, took me a few runs to figure out that I needed mail.jar and activation.jar in my classpath. After that, smooth sailing.
