What is the difference between JSF, Servlet and JSP?

JavaServer Faces (JSF) is a user interface (UI) framework for building web applications. It is designed to simplify the construction of user interfaces for Java EE applications using a component-based architecture.

Java Servlets are server-side programs that run on a web server and handle requests made by a client, usually a web browser. They operate on a request-response model and are used to extend the functionality of a web server by executing custom code to generate dynamic content.

JavaServer Pages (JSP) is a technology that allows developers to create dynamic web content by inserting Java code into HTML pages. JSP pages are compiled into servlets and run on the server, following the same request-response lifecycle as servlets but optimized for view generation.

To summarize, JSF is a component-based UI framework, Servlets handle request-response logic on the server, and JSP provides a templating approach for dynamic web content.
