public class ResourceLoader

extends java.lang.Object

Utility class for loading resources.
This class fixes an issue where the Scope library wants to load a resource belonging to a client jar, but cannot find it because of the resource is not accessible from the scope classloader.
The solution is to give access from Scope to the client classloader, i.e the classloader used to load the client jars containing the application resources.
User code needs to set the client classloader with ResourceLoader.setClientClassLoader before Scope can load the client resources.
