Is there a way to configure additional directory location, where JBoss AS could pick up configuration files such as -server.xml and -ds.xml files, in addition to the deploy directory?

I would need this capability to manage multiple sets of configuration files relevant to various deployment stages i.e. development, qa, production. Preferably, I could just change the configuration value (if one exists) specifying this additional configuration directory when switching deployment environments.

Thanks in advance,
