java .net logging log4net log4j

I would like to set the log file name for a log4j and log4net appender to have the current date. We are doing Daily rollovers but the current log file does not have a date. The log file name format would be

logname.2008-10-10.log

Anyone know the best way for me to do this?

edit: I forgot to mention that we would want to do this in log4net as well. Plus any solution would need to be usable in JBoss.

Answer

DailyRollingFileAppender is what you exactly searching for.

<appender name="roll" class="org.apache.log4j.DailyRollingFileAppender">
    <param name="File" value="application.log" />
    <param name="DatePattern" value=".yyyy-MM-dd" />
    <layout class="org.apache.log4j.PatternLayout"> 
      <param name="ConversionPattern" 
          value="%d{yyyy-MMM-dd HH:mm:ss,SSS} [%t] %c %x%n  %-5p %m%n"/>
    </layout>
  </appender>
