JSTL c:import Core Tag

The JSTL <c:import> Core Tag is used to include the content of other resources at a specific position in the current JSP. It works like include action but the difference is that it can work on relative as well as absolute url while include action can work only on relative url.

Syntax:

<c:import var="varName" url="relUrl/absUrl"/>

c:import tag attributes:

Attribute	Description	Required
url	URL to retrieve and import into the page.	Yes
context	/ followed by the name of a local web application.	No
charEncoding	Character set to use for imported data.	No
var	Name of the variable to store imported text.	No
scope	Scope of the variable used to store imported text.	No
varReader	Name of an alternate variable to expose java.io.Reader.	No

Example:

test.jsp

<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
 
<html>
    <head>
        <title>c:import JSTL core tag example</title>
    </head>
    <body>
        <c:import var="data" url="/showInfo.jsp"/>
        <c:out value="${data}"/>
    </body>
</html>
