This posting describes the steps necessary to change your Grails project if you’re using Grails for frontend only, without direct database access.
I was interested in whether there’s any truth in this startup-scene meme, so I took some time to walk through 13 startups who presented 30 second pitches at Web 2.0 summit 2010, a little more than one year ago.
While porting my Grails applications to 2.0 RC1, I recognized that ConfigurationHolder is now deprecated. The new way to access the configuration is through dependency injection of the grailsApplication bean. Before 2.0: With 2.0:
