we normally do this through a "distribution/release" script (or ant 
build) which you can configure and hence is copying different versions 
of these configuration files into the WAR or just patches them.

Another possibility would be of course to use Environment properties as 
we do for finding the realms.xml file,
which would overwrite the ones from the configuration files. See for example

src/core/java/org/wyona/yanel/core/map/RealmManager.java#getRealmsConfigFile(...)

but so far only the "realms.xml" is overwritten like this.
