JSP directives

JSP directives are special instructions that are used to provide instructions to the JSP container, and to configure various settings for the JSP page. The three main types of directives in JSP are page directives, include directives, and taglib directives.

• Page Directives:

Page directives are used to provide instructions to the JSP container about how to process the JSP page. The syntax for a page directive starts with the <%@ symbol and ends with the %> symbol. Here's an example of a page directive that sets the character encoding for the JSP page:

This directive sets the content type of the page to text/html, and sets the character encoding to UTF-8.

• Include Directives:

Include directives are used to include another file into the current JSP page. The syntax for an include directive starts with the <%@ symbol and ends with the %> symbol. Here's an example of an include directive that includes the contents of the file "header.jsp" into the current JSP page:

This directive includes the contents of "header.jsp" into the current JSP page at the location where the directive is placed.

• Taglib Directives:

Taglib directives are used to declare custom tags that are used in the JSP page. The syntax for a taglib directive starts with the <%@ symbol and ends with the %> symbol. Here's an example of a taglib directive that declares a custom tag library with the prefix "custom":

This directive declares the custom tag library located at "/WEB-INF/custom.tld", and assigns it the prefix "custom". This allows custom tags in the tag library to be used in the JSP page with the "custom" prefix.

Overall, JSP directives provide a way to configure and customize the behavior of JSP pages, and are an essential part of JSP development
