What do you mean by RMI and how it is useful?

Hi friend, the concept of RMI (Remote Method Invocation) is of great help when we go for creating Java based web applications.By RMI we can facilitate communication between two JVM on two different Machines.Thus if suppose that one server is located in USA and which has the cricket database and I from India want only current updated score information to be shown on my site then by using RMI I can call a method from India on the remote object located in USA and get the information I want without keeping the database on my Machine in India.Thus we can share the resources and make them more usefull.RMI is exciting, just experience its use and then you will come to know its importance.If you have any more querys or want RMI example then PM me and I will cretainly help you.

Using RMI , we can invoke a object in a remote places.

The concept os RMI is invoking a method which is not present in your JVM and that is the challenge in RMI,
