What is a JSP Directive? - Programmingempire

The following example describes What is a JSP Directive.

A JSP directive is a special type of JSP tag that we use at the beginning of a JSP file. In order to specify some kind of instructions to the JSP engine, we use directives. Directives are used to define global settings or attributes that affect the entire JSP page, and are not executed at runtime like JSP expressions or actions.

There are three types of JSP directives.

Page directive. Basically, it contains the instructions about the page itself, such as its language, import statements, error handling, and session handling. Page directives are typically used at the beginning of a JSP file and are denoted by the <%@ page %> tag. For Example.

<%@ page language="java" contentType="text/html; charset=UTF-8" %>

Include directive: This directive is used to include the contents of an external file or resource at the current location in the JSP page. Include directives are typically used to modularize JSP pages and are denoted by the <%@ include %> tag. For Example.

<%@ include file="header.jsp" %>

Taglib directive: This directive is used to import and define custom tag libraries that can be used in the JSP page. Taglib directives are typically used to extend the functionality of JSP pages and are denoted by the <%@ taglib %> tag. For Example.

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>

Overall, JSP directives provide a way to define global settings and attributes that affect the entire JSP page and can help to improve code modularity and maintainability.
