public class JamonInterceptorServiceImpl
extends BaseInterceptorServiceImpl
implements JamonInterceptorService, org.apache.avalon.framework.configuration.Reconfigurable, org.apache.avalon.framework.thread.ThreadSafe, org.apache.avalon.framework.activity.Disposable, org.apache.avalon.framework.activity.Initializable

A service using JAMon for performance monitoring. The implementation relies on reflection to invoke JAMON to avoid compile-time coupling.
