Meanwhile I found the solution (for all, who'll might have the same question
in future:) by defining an XML entity declaring the logfiles directory (or
any other parameter, required, to be referenced in the log4j.xml) - Sample:
"C:/MyProject/MyLogs">]>
class="org.apache.log4j.DailyRolling
You're right, I did miss something. I didn't see "log4j.logdir" being set
within the file in the original example. Sorry about that. Your original
answer appears to be right on the money.

Yes, exactly this is my main question (How to set a property, which can be
referenced in the xml config elsewhere? It works in flat log4j text config
files) - it's still open. Unfortunately I didn't even

Curt,
Maybe I'm missing something, but how does using XML entity refs do anything for
referencing Java system properties? The simple answer is that Log4j XML config
files support exactly the same syntax as properties files, e.g.,
I don't recall whether/where it's specifically docu
XML entity references can be used for that purpose and are defined in the XML
Recommendation (http://www.w3.org/TR/xml/#sec-references).

Hi,
actually you are right. I think we should improve our documentation here.
In meanwhile, please try this:
http://wiki.apache.org/logging-log4j/Log4jXmlFormat
Let me know if this solves your problems.

Hello,
usually in flat plain text log4j.config files global system properties can
be defined, which may be referenced in the configuration of different
appenders, e. g.
log4j.logdir=C:/Data/logfiles
...
log4j.appender.MyAppender1.File=${log4j.logdir}/MyAppender1.log
...
log4j.appender.MyAppen
