This page shows you the steps for creating an activatable object, by extending java.rmi.activation.Activatable . If you are interested in finding out about Making a UnicastRemoteObject Activatable or Activating an object that does not extend java.rmi.activation.Activatable , these are also available as tutorials. The RMI daemon, rmid , provides a JVM from which other JVM instances may be spawned. The reason for this omission, is that the client code for activatable objects is no different than the RMI client code for accessing non-activatable remote objects.
Activation is strictly a server-side implementation decision.
For this example, the implementation class will be examples.activation.ActivatableImplementation . For this example the setup class will be examples.activation.Setup . Do not use this policy file in a production environment . In the setup application,the job of the activation group descriptor is to provide all the information that rmid will require to contact the appropriate existing VM or spawn a new VM for the activatable object. The job of the activation descriptor is to provide all the information that rmid will require to create a new instance of the implementation class.
