log4j.RollingFileAppender neither rolling nor timestamping

New job, new language...java this time. I'm working on integrating log4j into a new product and have after some issues managed to get it sort of working but a problem remain and I'm not sure how to go about solving them.

Using log4j 1.2.17 with log4j-extras 1.2.17 for RollingFileAppender.

Problem

It's not rolling. I wanted to set it to rolling every minute while developing this to check that everything works, but all I get it logs/stuff.log.

LogTest.java

package logTest;

import org.apache.log4j.LogManager;
import org.apache.log4j.Logger;
import org.apache.log4j.xml.DOMConfigurator;

public class LogTest {

   static Logger logger = LogManager.getLogger(LogTest.class);

   public static void main(String[] args) {
      DOMConfigurator.configure("log4j.xml");

      logger.trace("trace");
      logger.debug("debug");
      logger.info("info");
      logger.warn("warn");
      logger.error("error");
   }
}

log4j.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">
<log4j:configuration debug="true"
                     xmlns:log4j='http://jakarta.apache.org/log4j/'>

   <appender name="consoleAppender" class="org.apache.log4j.ConsoleAppender">
      <layout class="org.apache.log4j.PatternLayout">
         <param name="ConversionPattern" value="%d{yyyy MM dd HH:mm:ss} %5p %c{1} - %m%n"/>
      </layout>
   </appender>

    <appender name="rollingAppender" class="org.apache.log4j.rolling.RollingFileAppender">
        <rollingPolicy class="org.apache.log4j.rolling.TimeBasedRollingPolicy">
        <param name="FileNamePattern" value="logs/stuff.%d{yyyy-MM_HH-mm}.gz"/>
        <param name="ActiveFileName" value="logs/stuff.log"/>
        </rollingPolicy>
        <layout class="org.apache.log4j.PatternLayout">
            <param name="ConversionPattern" value="%d{yyyy MM dd HH:mm:ss} %5p %c{1} - %m%n"/>
        </layout>
    </appender>
   <root>
      <level value="INFO"/>
      <appender-ref ref="consoleAppender"/>
      <appender-ref ref="rollingAppender"/>
   </root>
</log4j:configuration>

Your pattern is wrong for the rollingAppender...

%%d{yyyy MM dd HH:mm:ss}

You need to drop the first "%"

For the second problem, (and I've not used TimeBasedRollingPolicy) do you need to set the actual time window as a parameter?

I answered a post similar to this the other day, not sure if it is correct yet though. See Log4j2 auto rollover after specified duration
