org.eclipse.persistence.jpa.osgi.eclipselink.Activator

All Implemented Interfaces:

EventListener, org.osgi.framework.BundleActivator, org.osgi.framework.BundleListener, org.osgi.framework.SynchronousBundleListener

public class Activator
extends Activator
implements org.osgi.framework.SynchronousBundleListener

Activator for JPA OSGi service. This Activator recieves forwarded events from the activator in org.eclipse.persistence and allows EclipseLink's OSGi behavior to occur in an EclipseLink specific manner as defined in our 2.0 release. When the Eclipse Gemini project comes out of incubation that behavior will be decremented and users will be encouraged to use OSGi JPA in the way defined by the OSGi EE specification
