java log4j apache-commons

I'm working on a project that uses Log4J via Commons.

I'm trying to find the path to the log file, but I'm not finding an appropriate method that will return the logfile path from the Logger.

Anyone ever attempted this?

You have to get all appenders from the root logger and then get the name of the log file.

    Enumeration e = Logger.getRootLogger().getAllAppenders();
    while ( e.hasMoreElements() ){
      Appender app = (Appender)e.nextElement();
      if ( app instanceof FileAppender ){
        System.out.println("File: " + ((FileAppender)app).getFile());
      }
    }
