java rmi (remote method invocation) allows you to invoke methods on an object located in another jvm (java virtual machine). a common use case for rmi is implementing a callback mechanism where a client can register a callback with a server, and the server can call back to the client.

here’s a step-by-step tutorial on how to set up a simple java rmi callback system.

step 1: define the remote interface

first, you need to define a remote interface that extends `java.rmi.remote`. this interface will declare the methods that can be called from the client and the callback methods that the server can call.



step 2: create the server interface

next, create another remote interface for the server. this interface will allow clients to register their callbacks.



step 3: implement the server

now implement the server that will manage clients and invoke their callback methods.



step 4: implement the client

the client will implement the `callbackclient` interface and will register itself with the server.



step 5: set up the rmi server

to run the server, create a main method for it. here’s how you can do that:



step 6: running the example

1. **compile the code**: make sure to compile all your java files.
2. **start the rmi registry**: you can do this by running `rmiregistry` in the command line from the directory where your classes are located.
3. **run the server**: start the `callbackservermain` class.
4. **run the client**: start as many instances of the `callbackclientimpl` class as you want. each client will register itself with the server.

step 7: sending messages

to actually send messages to clients, you can modify the server to call `sendmessagetoclients` at some point, perhaps in response to a user action.

example usage

you can modify the server to automatically send a message after a few seconds:
