Ok,
I have set the system property before to initializing log4j
(just as test :
System.setProperty("log.name","temp.log");
DOMConfigurator.configure(PATH_TO_LOGS+"log4j.xml");
)
Then I change dynamically the system property to change the directory in
which the logs need to be stored :
System.setProperty("log.name",idRequest+".log");
But the logs keeps getting stored in temp.log

3. Both the system property and any needed directories need to be set
before log4j is configured. I created an appender that can create
directories as needed and it is at
http://stauffer.james.googlepages.com/DateFormatFileAppender.java
4. In your code you don't refer to a special appender, you refer to
special loggers.
i.e
Logger logger = Logger.getLogger(getClass().getName());
Logger specialLogger = Logger.getLogger("special." +
getClass().getName());
<logger name="special">
<level value="info"/>
<appender-ref ref="specialAppender" />
</logger>
<root>
<priority value ="info" />
<appender-ref ref="mainAppender" />
<appender-ref ref="consoleAppender" />
</root>
