The compute engine server accepts tasks from clients, runs the tasks, and returns any results. The server is comprised of an interface and a class. The interface provides the definition for the methods that can be called from the client. Essentially the interface defines the client's view of the remote object. The class provides the implementation.

Designing a Remote Interface

This section shows you the Compute interface, which provides the connection between the client and the server. You will also learn about the RMI API, which supports this communication.

Implementing a Remote Interface

This section explores the class that implements the Compute interface, thereby implementing a remote object. This class also provides the rest of the code that makes up the server program: a main method that creates an instance of the remote object, registers it with the naming facility, and sets up a security manager.
