No logging to secondary appender

[James Pittman]

I have a default appender set up, which is working fine.
But when I try to add another appender for a specific purpose, it doesn't
seem to be working.

XML:
<configuration xmlns="http://logging.apache.org/log4php/";>
    <!--
    ! Default appender.  Logs INFO and above to logs/cs2Log.log and
    ! does not append.
    !-->
    <appender name="default" class="LoggerAppenderFile">
        <layout class="LoggerLayoutPattern">
            <param name="conversionPattern" value="%date{Y-m-d H:i:s.u}
%C.%M(%L) %p %msg%n"/>
        </layout>
        <param name="file" value="/path/to/logs/cs2Log.log"/>
        <param name="append" value="false"/>
    </appender>

    <!--
    ! Appender to monitor tool activity  Logs INFO and above to
    ! logs/activity/activity.log, appending to the files.
    !-->
    <appender name="ActivityAppender" class="LoggerAppenderRollingFile">
        <layout class="LoggerLayoutPattern">
            <param name="conversionPattern" value="%date{Y-m-d H:i:s.u}
%C.%M(%L) %p %msg%n"/>
        </layout>
        <param name="file" value="/path/to/logs/activity/activity.log"/>
        <param name="append" value="true"/>
        <param name="maxFileSize" value="1024KB"/>
        <param name="maxBackupIndex" value="10"/>
    </appender>

    <!--
    ! Default logger.  Logs all classes using the default and console
    ! appenders.
    !-->
    <root>
        <appender_ref ref="default"/>
    </root>

    <logger name="activity">
        <appender_ref ref="ActivityAppender"/>
        <level value="info"/>
    </logger>
</configuration>

PHP:
<?php
require_once("log4php/Logger.php");
$logger = Logger::getLogger("main");
$activityLogger = Logger::getLogger("activity");

$activityLogger->info("Client IP: " . $_SERVER['REMOTE_ADDR']);
$activityLogger->info("Script URL: " . $_SERVER['SCRIPT_URL']);

$logger->warn("Yo.");
?>

I see all three log lines in my cs2Log.log file (the default)
but nothing in my activity.log.
The directory and file both exist, and permissions are not the issue.

Help?

Thanks,
Jamie
