DECLARATION IN JSP
In this Section, we will discuss about declaration of variables & method in JSP using declaration tags.
Using Declaration Tag, you can declare any number of variables & methods , as long as you end each declaration with a semicolon. The declaration must be valid in the Java programming language.
Point to remember before Declaration :
- Declaration must be end with semicolon .
- You can use those variables & methods directly in your JSP without declaring , which are already declared in package imported using <@ page> directive.
Note :- The scope of the declaration is JSP page means
it is valid only in JSP page & any of its static included files.The dynamic
files included with <jsp:include>, does not comes inside the scope of
declaration.
Syntax :
<%! declaration; [ declaration; ]+ ... %> |
Example :
|
<%@ page import="java.util.*" %>< HTML>< BODY><!-- Declaring variable & method --> <%! Date theDate = new Date();Date getDate() { System.out.println( "In getDate() method" ); return theDate;} %> Hello! The time is now <%= getDate() %></ BODY></ HTML> |
