GWT RPC

GWT RPC (Google Web Toolkit Remote Procedure Call) is a mechanism that allows a web application to communicate seamlessly between the browser (client) and server. It enables the client-side code, written in Java, to call methods on the server as if they were local functions, simplifying the process of exchanging data and commands. GWT RPC handles converting data into a format suitable for transmission, sending it over the internet, and then reconstructing it on the server side. This approach enhances the efficiency of building interactive, dynamic web apps by enabling smooth, structured communication between client and server components.
