Class Service
java.lang.Object
org.apache.commons.discovery.tools.Service
[this was ServiceDiscovery12... the 1.1 versus 1.2 issue
has been abstracted to org.apache.commons.discover.jdk.JDKHooks]
Implement the JDK1.3 'Service Provider' specification. ( http://java.sun.com/j2se/1.3/docs/guide/jar/jar.html )
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.-
