Using Activation: Overview

Documentation Contents

This set of tutorials describes how to use the Java^TM Remote Method Invocation (Java RMI) APIs to implement, to register, and to use activatable objects. Each tutorial presents a different way to implement an activatable object. All tutorials use the same parameterized setup program that registers information about an activatable object with the Java RMI Activation System Daemon (rmid).

The tutorials are as follows:

The Setup program
A parameterized program for registering an activation descriptor for an activatable object with rmid, and binding a stub for that activatable object in a registry so that clients can look it up.
Extending Activatable
An implementation that extends the class java.rmi.activation.Activatable, a class whose constructors export a remote object during construction.
Not Extending Activatable
An implementation that does not extend the class Activatable, but instead uses its static methods to export a remote object.
Using Persistence
An implementation that, during construction, uses a MarshalledObject in an object's activation descriptor to specify a file that contains the object's persistent state.
