RMI is one of the distributed computing technology alternative powered by Java . RMI stands for Remote Method Invocation ,to keep it SIMPLE it means accessing a service from DIFFERENT node ( i.e., accessing a service provided by an object on server machine , here an object in client JVM talks with object in the server JVM ). Java provides an API and base some classes ( in package java.rmi ) to perform these kind of OPERATIONS . We basically use this methodology when we need to publish an object at server side which exposes set of services ( as methods in Object oriented programming TERMINOLOGY ) and where in one or more clients access these services from remote machines. By this we are distibuting a common code in TWO different JVM's and we are able to access the code on different JVM.
