Of course it is possible to set -D System properites using Weblogic. You just
have to have access to the startup script, which is not guaranteed.
In any case, setting a system property does not fully solve the issue unless
there is only a single app running on the server. When there is more than one
app, setting a single system property to point to a log file path assumes that
you want all apps using the system property to log to the same directory. The
original request mentioned "I would prefer the log file to be under the same
folder application is installed".
In fact, I wrote a servlet context listener that does exactly this. It
dynamically determines the path of the current webapp and sets a system
property according to a naming convention making it possible to reference this
system property in your webapp. I know it works under Tomcat, but I can't
guarantee it will work under other appservers because I haven't tested under
other appservers. See....
http://wiki.apache.org/logging-log4j/AppContainerLogging
specifically, read the javadoc for InitContextListener...

I use Tomcat and I can set system properties. I would be very
surprise if you can't set system properties on WebLogic. This might
not work if you aren't given the rights to set system properties.
