here's one that that does debug lvl logging, creates new files every day, and writes it to D:/mylog.log

Code:

    log4j.rootLogger=debug,DRF
    #log4j.rootLogger=info, DRF
    #log4j.rootLogger=warn, C
    log4j.appender.DRF.File=D:/mylog.log


   # Setup the ConsoleAppender
    log4j.appender.C=org.apache.log4j.ConsoleAppender

    # Specify the layout (SimpleLayout or PatternLayout)
    log4j.appender.C.layout=org.apache.log4j.PatternLayout
    log4j.appender.C.layout.ConversionPattern=%d{dd MMM yyyy HH:mm:ss} [%-5p] %c - %m%n

   # Setup the DailyRollingFileAppender
    log4j.appender.DRF=org.apache.log4j.DailyRollingFileAppender



    # Rollover log file at the start of each week
    log4j.appender.DRF.DatePattern='.'yyyy-ww

    # Specify the layout (SimpleLayout, PatternLayout, or HTMLLayout)
    log4j.appender.DRF.layout=org.apache.log4j.PatternLayout
    log4j.appender.DRF.layout.ConversionPattern=%d{dd MMM yyyy HH:mm:ss} : [%-5p] %c %x - %m%n
