How to create global variables in a Grails project

Question

What\'s the best practice of making a variable that would be accessible by almost all classes in a Grails project? Is there a config file that I can use for storage of that data

Answer 1

With Grails 2.2

//In Config.groovy
myVar = '/My/Root/Images/Folder'

//In your Services/Controllers/etc..  
import grails.util.Holders
def grailsApplication = Holders.getGrailsApplication()

//access you variable
def myVar =  grailsApplication.config.myVar;
