The following is the syntax for the include directive:
<%@ include file="relativeURL" %>
As you can see the directive accepts a single file attribute that is used to indicate the resource whose content is to be included in the declaring JSP. The file attribute is interpreted as a relative URL; if it starts with a slash it's interpreted as relative to the context of the web application (namely a context-relative path), otherwise it's interpreted as relative to the path of the JSP that contains the include directive (namely a page relative path). The included file may contain either static content, such as HTML or XML, or another JSP page.
For example:
<%@ include file="/copyright.html"%>
Let's consider a real-world example of such a templating mechanism that utilizes the include directive to provide a consistent page layout for a web application.
Consider the following two JSP pages:
Header.jsp
<html>
<head><title>A Very Simple Example</title></head>
<body style="font-family:verdana,arial;font-size:10pt;">
<table width="100%" height="100%">
<tr bgcolor="#99CCCC">
<td align="right" height="15%">Welcome to this example...</td>
</tr>
<tr>
<td height="75%">
Footer.jsp
</td>
</tr>
<tr bgcolor=" #99CC99">
<td align="center" height="10%">Copyright ACompany.com 2003</td>
</tr>
</table>
</body>
</html>
As you can see, Header.jsp declares the starting elements of an HTML table that is to be 100 percent of the size of the page and has two rows, whereas Footer.jsp simply declares the closing elements for the table. Used separately, either JSP will result in partial HTML code that will look very strange to a user but when they're combined using the include directive it's easy to create consistent pages as part of a web application.
Let's see just how simple this basic template mechanism is to use:
Content.jsp
<%@ include file='./Header.jsp'%>
<p align="center">The Content Goes Here...!!!</p>
<%@ include file='./Footer.jsp'%>
