This class supports any VM, including JDK1.1, via org.apache.commons.discover.jdk.JDKHooks. The caller will first configure the discoverer by adding ( in the desired order ) all the places to look for the META-INF/services. Currently we support loaders. The findResources() method will check every loader.- Author:
