Java rmi Package
Java RMI (Remote Method Invocation) is a Java API (Application Programming Interface) that allows one Java Virtual Machine (JVM) to invoke methods on objects running in another JVM, located on the same host or on a different host on a network. RMI is a way to implement distributed computing in Java.
The RMI API is located in the java.rmi package and provides classes and interfaces that enable a client and server to communicate and invoke methods on remote objects. The RMI architecture includes the following components:
Remote Interface: An interface that extends the java.rmi.Remote interface and declares the methods that the remote object provides to the clients.
Remote Object: An object that implements a remote interface and provides the methods that the clients can invoke.
Registry: A service that provides a central directory for remote objects, allowing clients to look up the remote objects they need.
Stub and Skeleton: RMI uses stub and skeleton objects to communicate between the client and server. A stub is a client-side proxy for the remote object, while a skeleton is a server-side proxy for the remote object.
To use RMI, you need to perform the following steps:
- Create the remote interface and implementation classes.
- Compile the classes and generate stub and skeleton objects.
- Start the RMI registry.
- Create and bind the remote object to the registry.
- Create the client program that looks up the remote object and invokes its methods.
Overall, RMI provides a convenient way to implement distributed computing in Java, allowing objects to communicate across different JVMs and making it easier to build scalable and flexible applications.
