Oliver,
Thanks for that reference, and while that is somewhat helpful it means that for
each environment, we still need a separate properties file for each of the
environments and another one for the common stuff. Previously, we had
accomplished this before by conditionally loading files based upon path within
our XML file like:
<properties
fileName="${config.root}/test-app/environment/${config.env}/test.properties"
listDelimiter="|">
<reloadingStrategy refreshDelay="10000"
config-class="org.apache.commons.configuration.reloading.FileChangedReloadingStrategy"
/>
</properties>
My hope was to find a way to do that a little bit more concisely within a
single file or as I mentioned hooking into the property loading process.
Thanks,
Ron

You might want to have a look at multi-tenant configurations [1]. If I
understand you correctly, this feature solves your problem. It is possible to
access different configuration sources based on interpolated properties. System
properties or environment variables can also be used to determine the set of
properties available.
