|
|
In the previous Classpath releases, an instance of a UnicastRemoteObject
|
|
could be accessed from a server that:
|
|
<ul>
|
|
<li>has created an instance of that object<li>
|
|
<li>has been running <i>all<i> the time</li>
|
|
</ul>
|
|
<p>The the activation system allows to activate and execute the object
|
|
implementation on demand rather than running all time. If the activation
|
|
system is persistent, the server can be terminated and then restarted.
|
|
The clients, still holding remote references to the server side
|
|
activatable objects, will activate those objects again. The server side
|
|
objects will be reinstantiated (activated) during the first call of any
|
|
remote method of such object.
|
|
</p><p>
|
|
The RMI client code for activatable objects is no different than the code for
|
|
accessing non-activatable remote objects. Activation is a server-side feature.
|
|
</p><p>
|
|
In order for an object to be activated, the "activatable" object class
|
|
(independently if it extends the {@link Activatable} class or not) defines a
|
|
special public constructor that takes two arguments, its activation identifier
|
|
({@link ActivationID}) and its activation data ({@link java.rmi.MarshalledObject}),
|
|
supplied in the activation descriptor used during registration. When an
|
|
activation group activates a remote object, it constructs the object via
|
|
this special constructor. The remote object implementation may use the
|
|
activation data to initialize itself in a needed manner. The remote object may
|
|
also retain its activation identifier, so that it can inform the activation
|
|
group when it becomes inactive (via a call to the Activatable.inactive method).
