JSP include Directive





include Directive


The JSP include directive allows you to include the content of a web page in the current page. The location where you insert the include directive is very important because it is at that specific location where the content of another web page is added to the current web page.




Syntax of include Directive


<%@ include file = " relative URL of the file " %>





include Directive Example


We have created a JSP web page that displays the current day, date and time, as shown below.

Date.jsp
<html>

<head>
<title>Display Date</title>
</head>


<body>

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

Current Date and Time : <%= new Date() %>

</body>

</html>



Next we have created a web page that uses include directive to include the contents of a web page Date.jsp(which displays the current date and time) at a particular location of the current web page.



IncludeExample.jsp
<html>

<head>
<title>Display Date</title>
</head>


<body>

Including the content of another page using include directive :
<%@ include file="Date.jsp" %> </body> </html>



executing this JSP page includes the content of Date.jsp and displays it the user.






Another example of include directive


In this example, we are going to include a webpage with a form, using include directive.

login1.jsp
<html>

<head>
<title>Login Form</title>
</head>


<body>


<form action="login.jsp" method="post">
    <b>Username</b>
    <input type="text" name="username">
    <b>Password</b>
    <input type="password" name="password">
    <button type="submit">Login</button>
</form>

</body>

</html>




IncludingExample2.jsp
<html>

<head>
<title>Using include directive</title>
</head>


<body>


Including the content of another page using include directive :
<%@ include file="login1.jsp" %> </body> </html>



executing IncludingExample2.jsp webpage displays the including contents of login1.jsp to the user.
