Examples of org.osgi.jmx.framework.BundleStateMBean

org.osgi.jmx.framework.BundleStateMBean
This MBean represents the Bundle state of the framework. This MBean also emits events that clients can use to get notified of the changes in the bundle state of the framework. @version $Id: f5d5197fdabb4e0c420bc47812d38fd14edb61d0 $ @ThreadSafe
