In this tutorial how to perform RMI (Remote Method Invocation) in Advance Java (J2EE) is shown.<\/p>\n
RMI system allows an object running in one Java Virtual Machine (JVM) to invoke methods of an object running in another JVM.<\/p>\n
Code:<\/p>\n
<\/p>\n
Prime.java<\/p>\n
import java.rmi.*;<\/p>\n
public interface Prime extends Remote
\n{
\npublic int check_prime(int no) throws RemoteException;
\n}<\/p>\n
<\/p>\n
Prime_Impli.java<\/p>\n
import java.rmi.*;
\nimport java.rmi.server.*;<\/p>\n
public class Prime_Impli extends UnicastRemoteObject implements Prime
\n{
\npublic Prime_Impli() throws Exception{}<\/p>\n
public int check_prime(int no) throws RemoteException
\n{
\nint i,cnt=0;
\nfor(i=2;i<=no\/2;i++)
\n{
\nif(no%i==0)
\n{
\ncnt++;
\nbreak;
\n}
\n}
\nreturn(cnt);
\n}
\n}<\/p>\n
<\/p>\n
Prime_server.java<\/p>\n
import java.rmi.*;
\nimport java.net.*;<\/p>\n
public class Prime_server
\n{
\npublic static void main(String args[])
\n{
\ntry
\n{
\nPrime_Impli primpli=new Prime_Impli();
\nNaming.rebind(“RmiPrime”,primpli);
\n}
\ncatch(Exception e)
\n{
\nSystem.out.println(e);
\n}
\n}<\/p>\n
}<\/p>\n
<\/p>\n
Prime_client.java<\/p>\n
import java.io.*;
\nimport java.rmi.*;
\nimport java.net.*;<\/p>\n
public class Prime_client
\n{
\npublic static void main(String args[])
\n{
\ntry
\n{
\nString url=”rmi:\/\/localhost\/RmiPrime”;
\nPrime intf=(Prime)Naming.lookup(url);<\/p>\n
BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
\nSystem.out.println(“Enter a no:”);
\nint no=Integer.parseInt(br.readLine());
\nint x=intf.check_prime(no);
\nif(x==0)
\nSystem.out.println(no+” is a prime number”);
\nelse
\nSystem.out.println(no+” is a composite number”);
\n}
\ncatch(Exception e)
\n{
\nSystem.out.println(e);
\n}
\n}
\n}<\/p>\n
