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.
