my applications (multiple .ear and .war files) use properties files for configuration of misc things, url's to other systems, feature toggles +++. Pre AS7 I had these .properties files as an exploded .jar in the lib folder. After upgrading to AS7 this is not an option anymore, so I've created a module that basically is an exploded .jar in the modules folder, and all my applications have a dependency to this module in MANIFEST.MF.
This works for me, but I'm curious about how others are solving this. Am I the only one that uses .properties files that need to be changed at runtime?
