According to this page: http://logging.apache.org/log4j/1.2/manual.html

The preferred way to specify the default initialization file is through the log4j.configuration system property. In case the system property log4j.configuration is not defined, then set the string variable resource to its default value "log4j.properties".

So if you set the log4j.configuration system property before log4j is dynamically loaded (i.e., referenced in any object), then log4j will use that value for the name of the config file.

   System.setProperty("log4j.configuration","abclog4j.properties"); 

You could do this in a static block at the beginning of some base class so that it is set before any log4j references are encountered.
