Variable and method declaration in JSP

Hi Ervin,

variable declaration section:- This section can be used in a jsp to declare page scope variables and methods. This section can appear before any html tags.

 

Syntax:-

<%! Declaration of variables or methods %>

Ex:- <%! int x=100; %>


The JSP you write turns into a class definition.  All the scriptlets you write are placed inside a single method of this class.

You can also add variable and method declarations to this class.  You can then use these variables and methods from your scriptlets and expressions.

To add a declaration, you must use the <%! and %> sequences to enclose your declarations, as shown below.

<%@ page import="java.util.*" %>


<%!
    Date theDate = new Date();
    Date getDate()
    {
        System.out.println( "In getDate() method" );
        return theDate;
    }
%>
Hello!  The time is now <%= getDate() %>





Thanks
