Recent projects have provided or called other interfaces, in the end of the tangle is the use of servlets or webservice, so the internet to see the difference between them and RMI, easy to deepen understanding. First compare under servlet and WebServiceRequest:Servlet: Provides the request/Response mode, is a Java specification, can only be used in Java, to replace the difficult to understand the early use of CGI, is a stateless request response, the

1.RMIRMI is a typical Java custom Remote communication protocol, we know that in a single VM, we can directly invoke the Java object instance to achieve communication, then in the remote communication, if you can also follow this way is of course the best, This remote communication mechanism became RPC (remote Procedure call), and RMI was born to this goal.Consider the principle of a complete remote communication process based on

-------------------------------------------------------------- Haven't updated the blog for a long time, today to a. -------------------------------------------------------------- 0x00 Introduction The Java RMI service is a remote method call (invocation). It is a mechanism that enables an object on one Java virtual machine to invoke the method of another Java virtual machine object. In the Java Web, RMI is

Using eclipse to develop RMI under linux-centos6.3, launch the Tomcat service and discover "ObjID already in use" error. The log interception is as follows: ERROR [Org.springframework.web.context.ContextLoader] context initialization failed Org.springframework.beans.factory.BeanCreationException:Error creating Bean with Name ' Avmremoteservice ' ... : Internal Error:objid already in use analyzes the cause of the error, which should be attributed

RMI is shorthand for remote method invocation. As the name implies, it is the object on one machine that calls the object on the other machine. The use of RMI is very simple, first of all the server defines an interface (interface to extend the remote interface), and then implement this interface (to extend the UnicastRemoteObject), and then bind to the naming static class. The client gets a remote object t

One of the main features of CORBA, as we already know, is support for RPC (remote procedure calls). Using this technique, our local object can invoke the method within the remote object of the location. Of course, there is already an inherent Java feature that can do exactly the same thing: RMI (refer to chapter 15th). Although RMI makes it possible to make RPC calls between Java objects, CORBA can rpc betw

RMI (remote method invocation) is a remote procedure call in Java (Procedure call,rpc) Implementation, is a distributed Java application implementation. Its purpose is to shield developers from the details of different JVMs and network connections, so that objects distributed across different JVMs can be easily communicated with each other as if they exist in a unified JVM. Communication involves the encoding and decoding of data, we do not need to do

RMI for C ++ is a remote method calling framework designed for the C ++ language. Unlike CORBA, RMI is suitable for interoperability between different programming languages, RMI for C ++ is designed for C ++, so it is more efficient, faster, and more convenient to develop.

When we look at the export mechanism provided by spring for RMI, we see the rmibasedexporter class. When we develop RMI to call the service interfaceYou do not need to implement the remote interface. Spring automatically generates a proxy object (rmiinvocationwrapper) for the Service Interface object at startup. This proxy class implements the remote interface.

The remote method call (RMI) mechanism can further extend the object-oriented idea because you can invoke objects not only on this machine, but also on other hosts.
