Hi Friend,

Template Data is a parameterized content that allows the JSP document to generate a response stream of characters.

JSP Elements provides information that will be translated and executed by the JSP server.

Types of JSP elements:
1)Directive Element: It provides global information for the translation phase.
<%@ page language="java" %>

2)Scripting Element: It provides embedded Java statements. There are three types of scripting elements:
a)Declaration Element: It provides the embedded Java declaration statements to be inserted into the Servlet class.

<%! Java decalaration statements %>

b)Scriptlet Element: It provides the embedded Java statements to be executed as part of the service method of the Servlet class. There are two ways to write a scriptlet element:

<% Java statements %>

c)Expression Element: It provides the embedded Java expressions to be evaluated as part of the service method of the Servlet class.

<% Java expressions %>

Thanks
