RMI architecture

The remote method invocation goes through a STUB on the client side and a so called SKELETON on the server side.

STUB

A stub for a remote object acts as a client's local representative for the remote object. In RMI, a stub for a remote object implements the same set of remote interfaces that a remote object implements.

SKELETON

When a skeleton receives an incoming method invocation it does the following:

• Unmarshals (reads) the parameters for the remote method,
• Invokes the method on the actual remote object implementation, and
• Marshals (writes and transmits) the result (return value or exception) to the caller.

RMI registry

I have started the RMI Registry within the server JVM, via the LocateRegistry.createRegistry() API.
(Default port: 1099)

• Remote objects can be listed in the RMI Registry.
• Clients can get a reference to the remote object by querying the Registry.
• After that, the client can call methods on the remote objects.
  

Establishing connection with Telnet

From the client machine

1. Activate Telnet protocol.
2. Find out the ip address of the server.
3. Type Telnet <IP Address> <port number> Note: Do not include the <> when entering the IP Address and the Port Number.
