log4j-1.3alpha-7 - config load/reload? and watchdog?

[Jon Wilmoth <JW...@starbucks.com>]

I'm trying to upgrade to log4j-1.3alpha-7, but not seeing what I would
expect...which is hopefully user error.

First, I thought I could replace my call to
DOMConfigurator.configureAndWatch(<LOG4J_CONFIG_FILE>,
<LOG4J_CONFIG_FILE_CHECK>);

With:

JoranConfigurator joran = new JoranConfigurator();
joran.doConfigure(<LOG4J_CONFIG_FILE>,
LogManager.getLoggerRepository());

However, I don't see log events being sent to my appender.  Inserting
the following:  System.setProperty("log4j.configuration",
<LOG4J_CONFIG_FILE>);  
Forces the events to the log file appender I've set up.

Secondly, how do I force a reload of the config?

Third and finally can I specify any other a %d conversion specifier in
the FileNamePattern param for the TimeBasedRollingPolicy?  I have two
server that I'd like to share the same log4j config, but I'd like the
server log files to go to two different directories.  Ideally I could
specify the following (where %s{server.name} is a jvm system property
that evaluates to "server1" for one server and "server2" from another
jvm):

<appender name="LOGFILE"
class="org.apache.log4j.rolling.RollingFileAppender">
  <rollingPolicy
class="org.apache.log4j.rolling.TimeBasedRollingPolicy">
     <param name="FileNamePattern"
value="/var/tmp/%s{server.name}/server.%d{yyyy-MM-dd}.log.gz"/>
  </rollingPolicy>
  <layout class="org.apache.log4j.PatternLayout">
     <param name="ConversionPattern" value="%d{MMM-dd-yyyy h:mm:ss:SSS
a, z} [%-5p] (%l) - %m\n"/>
  </layout>
</appender>
