technology is based on the Java platform, it brings the Security and portability of the Java platform to distributed computing. RMI greatly extends Java's network computing capabilities. It provides a powerful system platform for compiling enterprise-level Internet/Intranet applications based on distributed object technology.The architecture of Java RMI is as fo

1. Create a server-side project in Eclipse. Then, create an interface that is the method definition that you want to open to the client side. It is called: Usermanagerinterface, and must inherit the remote interface.1 Packagedataserver.rmi.stub;2 3 ImportJava.rmi.Remote;4 Importjava.rmi.RemoteException;5 6 ImportDataserver.rmi.bean.Account;7 8 Public InterfaceUsermanagerinterfaceextendsremote{9 PublicString GetUserName ()throwsremoteexception;Ten PublicAccount Getadminaccount ()th

with the hardware platform, RMI can run smoothly without transplantation, regardless of homogeneous or heterogeneous systems.RMI provides a simple and direct model for Distributed Computing On the Java platform. Because Java's RMI technology is based on the Java platform, it brings the Security and portability of the Java platform to distributed computing.

so that they can accept remote calls. This step can be included in a method of a remote object, or in an entity object in another class. This step is done in the following steps:? Create and install a security manager? Create and publish one or more remote objects? Register at least one remote object using RMI registryThe purpose of implementing the security Man

create an instance of a remote object and start the registry service from the specified port number through the Createregistry method of the Java.rmi.registry.LocateRegistry class, or by executing The Rmiregistry command starts the registry service, and the default run port for the registry service is 1099.code Example 3 package Com.itjob.rmi ; import java.rmi.*;import java.rmi.registry.*;public class rmisampleserver{public static void Main (String [] args) {/* Create and instal

Configure and run the RMI Service, right-click the rmi_server.java file in the tree on the left (the class implemented by your server interface), and choose debug as> RMI application. In the displayed dialog box, find the RMI Properties tab. The first two items are displayed in red. Select Java.

serialization of Java objects is: Provides a simple but extensible mechanism to maintain the type and security attributes of Java objects in a serialized manner, with extended capabilities to support marshalling and reconciliation to meet the needs of remote objects; scalability to support simple persistence of Java objects; You need to provide serialization implementations for each class, and allow objects to define their external formats. Third, t

Because rmi has security restrictions,

In the Java world, there is a technique for "cross-virtual machine" calls, which is RMI (remote method Invocation, a long-distance methods call). For example, service a runs in JVM1, service B runs in JVM2, and service A and service B can call each other remotely, just as you would call a local method, which is RMI. In distributed systems, we use RMI technology t

Java RMI (remote method invocation) is implemented in JDK1.1 with Java, which greatly enhances the ability of Java to develop distributed applications. Java as a rage network development language, its great power is embodied in its powerful development of distributed network applications, and RMI is the development of pure Java Network Distributed Application System is one of the core solutions. It can actu

Because Java has a wide and powerful function, such as Cross-platform, code portability, security, efficiency and so on, it can realize distributed computing with its own mechanism when developing network distributed application, a kind of Java based remote method call (RMI) For our development of enterprise distributed applications provide an effective solution.

RMI starts with Java1.1, and RMI enables Java applications that run on different JVMs, including different hosts, to talk to each other. That is, a Java application in a JVM can invoke a method defined by an object on another JVM (a remote object). Java RMI is of great significance. RMI has important applications in Ja
