What are the different types of JSP tags?

The different types of JSP tags are as follows:

What are JSP directives?

·JSP directives are messages for the JSP engine. i.e., JSP directives serve as a message from a JSP page to the JSP container and control the processing of the entire page

·They are used to set global values such as a class declaration, method implementation, output content type, etc.

·They do not produce any output to the client.

·Directives are always enclosed within <%@ ….. %> tag.

Ex: page directive, include directive, etc.

What is page directive?

·         A page directive is to inform the JSP engine about the headers or facilities that page should get from the environment.

·         Typically, the page directive is found at the top of almost all of our JSP pages.

·         There can be any number of page directives within a JSP page (although the attribute – value pair must be unique).

·         The syntax of the include directive is: <%@ page attribute="value">

·         Example: <%@ include file="header.jsp" %>
