I have an ApplicationServer with deployed Java Beans.

no additional "child" log4j.properties should be used e.g. in Beans/WebApps.

Is that a package you refer to with directory syntax? If so, it's
rather unconventional (but not completely unheard-of) to use mixed-
case package names.

In the central log4j.properties file I defined an additional "private" logfile:

log4j.RootLogger=INFO, .......
...
log4j.appender.mylogfile1234=org.apache.log4j.RollingFileAppender
....

How can I access exactly this fileappender from my java source?

All log.info(..) output from MY java app should go to MY private logfile
but NOT to the other possibly defined logfiles in log4j.properties.
Conversely all log output from other beans should NOT go to my logfile.

How can I address my private logfile?

At first I though that:

private final Log log = Logfactory.getLog("mylogfile1234");

does the trick but it does not help.

Any other solution?

Set additivity to 'false'.

Google around for exact syntax in properties files.
