CometD vs JSP: What are the differences?

## Introduction
In this comparison, we will explore the key differences between CometD and JSP.

1. **Communication Protocol**: CometD is based on the Bayeux protocol, a publish-subscribe messaging system, while JSP (JavaServer Pages) is a technology that helps developers create dynamically generated web pages.

2. **Real-time Interactivity**: CometD is ideal for real-time applications where clients need to receive updates instantly, while JSP is better suited for generating dynamic content on the server side before sending it to the client.

3. **Client-Side vs Server-Side Rendering**: CometD enables client-side rendering of data by pushing updates to the browser without a page refresh, while JSP generates dynamic content on the server side before sending it to the client.

4. **Event-Driven vs Request-Response**: CometD follows an event-driven architecture, where events trigger actions on the client side in real-time, while JSP operates on a request-response model, where clients request data from the server and receive responses.

5. **Asynchronous Communication**: CometD supports asynchronous communication between clients and servers, allowing for non-blocking interactions, whereas JSP is synchronous in nature, where clients wait for responses from the server.

6. **Technology Stack**: CometD typically uses WebSocket and long-polling as transport mechanisms for real-time communication, while JSP is part of the Java EE technology stack for server-side web development.

In Summary, CometD and JSP differ in communication protocols, real-time interactivity, client-side vs server-side rendering, event-driven vs request-response architecture, asynchronous communication, and technology stack.
