What is the configuration setting for modifying the default homepage in a Grails application to no longer be appName/index.gsp? Of course you can set that page to be a redirect but there must be a better way.
Add this in UrlMappings.groovy
"/" { controller = "yourController" action = "yourAction" }
By configuring the URLMappings this way, the home-page of the app will be yourWebApp/yourController/yourAction.
