org.silverpeas.core.util.ConfigurationClassLoader

public class ConfigurationClassLoader
extends ClassLoader

The resource bundles and the properties files and all located into a particular directory in the Silverpeas home directory that isn't in the classpath of the running JEE application. Therefore this class loader aims to manage the access to the resources in this particular location; it acts as a bridge between the current hierarchy of class loaders and this particular unmanaged location.

By default, when a resource is asked, it looks for in the current hierarchy of class loaders before to seek the resource into the resources directory in the Silverpeas home directory.
