By default Grails uses the following locations to look for config files:
But this leads to conflicts if two (or more) versions of the same application (with the same app name) are runing in the same servlet container. I need this for testing.
How can I use different config files for two Grails applications with the same name in the same servlet container?
Maybe by Externalize Your Grails Configuration. Here is a good link : externalize grails configuration
I hope this help.
