编写 RMI 服务器

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

设计远程接口

This section explains 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.

实现远程接口

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, including a main method that creates an instance of the remote object, registers it with the RMI registry, and sets up a security manager.
