It returns an array of the names of the remote objects bound in the registry. It binds the remote object to the new name. It destroys the remote object which is bound with the given name. It binds the remote object with the given name. It returns the reference of the remote object. The Naming class provides methods to get and store the remote object. Now rmi services need to be hosted in a server process. There is only one method named add() and it declares RemoteException. Here, we are creating a remote interface that extends the Remote interface. The return value is sent back to the proxy object and then to the client application.įor creating the remote interface, extend the Remote interface and declare the RemoteException with all the methods of the remote interface. The client application invokes methods on the proxy object, RMI sends the request to the remote JVM. In the rmi application, both client and server interacts with the remote interface. The client application need only two files, remote interface and client application. In this example, we have followed all the 6 steps to create and run the rmi application.

Create and start the client application.

Create and start the remote application.

Start the registry service by rmiregistry tool.

Compile the implementation class and create the stub and skeleton objects using the rmic tool.

Provide the implementation of the remote interface.

The is given the 6 steps to write the RMI program.

The RMI application have all these features, so it is called the distributed application.

The application need to load the class definitions for the objects.

It need to provide the communication with the remote objects, and.

The application need to locate the remote method.

If any application performs these tasks, it can be distributed application. Understanding requirements for the distributed applications In the Java 2 SDK, an stub protocol was introduced that eliminates the need for skeletons.

It writes and transmits (marshals) the result to the caller.

It invokes the method on the actual remote object, and.

It reads the parameter for the remote method.

When the skeleton receives the incoming request, it does the following tasks: All the incoming requests are routed through it. The skeleton is an object, acts as a gateway for the server side object. It finally, returns the value to the caller.It reads (unmarshals) the return value or exception, and.It writes and transmits (marshals) the parameters to the remote Virtual Machine (JVM),.It initiates a connection with remote Virtual Machine (JVM),.When the caller invokes method on the stub object, it does the following tasks:

It resides at the client side and represents the remote object. All the outgoing requests are routed through it. The stub is an object, acts as a gateway for the client side. Let's understand the stub and skeleton objects: stub RMI uses stub and skeleton object for communication with the remote object.Ī remote object is an object whose method can be invoked from another JVM. The RMI provides remote communication between the applications using two objects stub and skeleton. The RMI allows an object to invoke methods on an object running in another JVM. The RMI (Remote Method Invocation) is an API that provides a mechanism to create distributed application in java. Requirements for the distributed applications.
