RMI is used to used to communicate betwwen two remote JVM. It is just like Remote Procedural Call(RPC). In RMI, We can pass/recieve Obejcts  as parameters. It is possible due to serialization of data.

If U want a bulid a Distributed Application in Java , we have to for RMI. Here, U must keep one constraint in mind : i.e., We should have JVM at both the ends. This is known as Distributed Object MOdel (DOM) in Java. It is possible for a remote client to access the server methods and avail any special specail services provided by him. More over RMI is based on 3-tier architecture, where RMI server object implements the business logic. For example, U can write a program for online train/flight resrvation system, in which the server implements the business logic ---Connecting to the data base and allocating the seats for the client. Here, the client accesses the server from a remote place (from a JVM only). We can build similar application using other DOM technologies like:CORBA tec.,

RMI is also used to maintain a seperate connection between two hosts in the NET.
