Log4j directing log output to directory?

Question

Ok how do you direct the log output to a directory? Below is a small snippet that does some log4j stuff using a properties file. Please excuse the crudeness of my directory structure. This will not be the final structure.
This is the logging app:package src.gov.osti.exceptions;
import org.apache.log4j.Logger;
import org.apache.log4j.Level;
import org.apache.log4j.SimpleLayout;
import org.apache.log4j.FileAppender;
import org.apache.log4j.PropertyConfigurator;
import java.io.IOException;
import java.lang.Object;
public class Log4JTest
   /** Creates a new instance of Log4JTest */
   public Log4JTest()
   public static void main(String[] args)
      //PropertyConfigurator.configure("log4j.properties");
      PropertyConfigurator.configure("/home/orozcom/proj/examples/WEB-INF/log4j.properties");
      Logger logger = Logger.getLogger("simple");
      logger.debug("A debug message");
      logger.info("A info message");
      logger.warn("A warn message");
      logger.error("A error message");
      logger.fatal("A fatal message");
This is the log4j.properties file:
# A simple logger
log4j.logger.src.osti.gov.exceptions.simple=DEBUG, simple
# This simple example will log to a file
log4j.appender.simple=org.apache.log4j.FileAppender
log4j.appender.simple.File=log4jsimple.log
# We will use a simple layout for this example
log4j.appender.simple.layout=org.apache.log4j.SimpleLayout
This is the testing directory which is local:
/home/orozcom/proj/examples/src/gov/osti/exceptions
This is the final directory Structure.
/app/tomcat/webapps/proj-name/logs
The proj-name is of couse the name of the app, and inside each app will be logs directory to log to.
How do I set up each app to log to its own logs directory?

Answer 1

Just to close this out. I figured it out on my own through alot of trial and error. The problem was that for some dumb reason (My Own Dumb Reason), I was trying to write to a file in the class itself, instead of change the directory in the properties file. When I look back I realize how dumb that was? Why was I looking in the class to write to a log file? Any way you can specify anywhere you want the log to go:
log4j.appender.simple.File=/home/orozcom/proj/examples/logs/log4jsimple.log
log4j.appender.simple.File=/tomcat/logs/log4jsimple.log
