Subject Re: Communcating An Own Properties-Object To log4j As Substtution For System-Properties
Date Fri, 16 Nov 2012 17:03:41 GMT

Well, you can manually bind properties at configuration time by loading the 
config as a properties object, adding more properties, and then calling 
configure(Properties) [1].  It's not clear to me how this might be done with 
XML configuration, thought I vaguely recall it being talked about in the past?
