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.

Java Servlets are server-side programs that run on a web server and handle requests made by a client, usually a web browser. They are used to extend the functionality of a web server and provide a way to execute custom code on the server 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, so they can be used to create dynamic content in the same way as servlets.

To summarize, JSF is a UI framework, Servlets are used to create dynamic content on the server, and JSP is a technology for creating dynamic web content by inserting Java code into HTML pages.
