Java Enterprise in a Nutshell, Second Edition

Name

Activator

Synopsis

An Activator is responsible for activating remote objects and their groups. Its only method, activate(), triggers the activation system protocol. The activator first finds the ActivationDesc matching the given ActivationID, and checks the activation information contained in it. If the target group for the object is not active, then the Activator starts its Java VM and activates the group object itself. Finally, the Activator tells the group to (re)create the object by calling the newInstance() method on the group.

                  
public interface Activator extends Remote {
// Public Instance Methods
   public abstract MarshalledObject activate(ActivationID id, 
        boolean force) throws ActivationException, 
        UnknownObjectException, RemoteException;  
}
