public class TenantSpecificResourceLoader
extends Object

A class that looks for a specific resource (using tenantSpecificPath) from the class path. If the tenant specific resource is not found then a generic path (genericPath is used. The resource is then opened and the name and URL are returned by calling obtainFileName(String, String) and obtainURL(String, String) Variable %{name} and %{tenantId} can be used for finding the name of the resource in both the generic and tenant specific paths.
