Java RMI Simple Example

The example RMI is the specification of a remote invocation of the Java platform, and here is a small example of the native test passing

A total of three Java classes, remote interfaces, server-side programs, client programs

Remote interface:

Import java.rmi.*;

Public interface Helloin extends java.rmi.remote{
String SayHello () throws remoteexception;
}

Service-Side programs:

Import java.rmi.*;
Import java.net.*;
Import java.rmi.registry.*;
Import java.rmi.server.*;

public class Hello extends Java.rmi.server.UnicastRemoteObject implements helloin{
Public Hello () throws remoteexception{
Super ();
}
Public String SayHello () throws remoteexception{
return "hello,world!";
}
public static void Main (string[] args) {
System.setsecuritymanager (New Java.rmi.RMISecurityManager ());
try{

Hello h=new hello ();
Java.rmi.Naming.rebind ("Hello", h);
System.out.print ("Ready ...");
}
catch (Exception e) {
E.printstacktrace ();
}

}
}

Start the RMI registration program on the command-line before executing the server-side program: Start Rmiregistry

Client program:

Import java.rmi.*;
Import java.rmi.registry.*;

public class helloworld{
public static void Main (string[] args) {
System.setproperty ("Java.security.policy", "Client.policy");
System.setsecuritymanager (New Java.rmi.RMISecurityManager ());
try{
Helloin hi= (Helloin) naming.lookup ("//fengl/hello");
for (int i=0;i<10;i++) {
System.out.println (Hi.sayhello ());
}
}
catch (Exception e) {
E.printstacktrace ();
}
}
}

Use Rmic Hello to generate stub and skeleton class before executing the client program, which
is actually the underlying implementation of the remote call.

Finally, execute the Java Helloworld console to print out the Hello,world, successfully invoked.
