You need to create a server application and host rmi service Adder in it. Public class Adder extends UnicastRemoteObject implements AddServerInterface Public interface AddServerInterface extends Remoteįor implementation of remote interface, a class must either extend UnicastRemoteObject or use exportObject() method of UnicastRemoteObject class. To be a remote interface, a interface must extend the Remote interface of java.rmi package. Clients program communicate to remote interfaces, not to classes implementing it. Creating a Simple RMI application involves following stepsĪ remote interface specifies the methods that can be invoked remotely by a client. It is responsible for passing request from Stub to remote object. Skeleton object resides on server program. It establish the connection between remote object and transmit request to it. It resides on Client side and communicate with Skeleton object. Stub act as a gateway for Client program. It then writes and transmits the parameters for the result.The method is invoked on the remote object.All the Parameters are read for the remote method.When a Server invokes the method on the skeleton object following things are performed internally: In RMI, a skeleton is an object that is used as a Gateway for the server-side.All the incoming request are sent through it. At last, it returns the value to the client.Now it reads the value or exception which is come as an output.After the 2nd step, it then waits for the output.It then transmits the parameters to the Remote Virtual Machine.A connection is established using Remote Virtual Machine.When a client invokes the method on the stub object following things are performed internally: All the outgoing request are sent through it. In RMI, a stub is an object that is used as a Gateway for the client-side. Stub and Skeleton are two important object used for communication with remote object. A Client program make request for remote objects on server and invoke method on them. A Server program creates some remote object, make their references available for the client to invoke method on it. Concept of RMI applicationĪ RMI application can be divided into two part, Client program and Server program. RMI is used for building distributed application. RMI provide remote communication between java program. Remote method invocation(RMI) allow a java object to invoke method on an object running on another machine.
