JSTL – Import Tag <c:import>

JSTL Import tag is being used in JSP to include the content of other resource in the current JSP. The <c:import> tag provides all of the functionality of the <include> action but also allows for inclusion of absolute URLs.

For example, using the import tag allows for inclusion of content from a different Web site or an FTP server.

Attribute:
The <c:import> tag has following attributes:

Attribute	Description	Required	Default
url	URL to retrieve and import into the page	Yes	None
context	/ followed by the name of a local web application	No	Current application
charEncoding	Character set to use for imported data	No	ISO-8859-1
var	Name of the variable to store imported text	No	Print to page
scope	Scope of the variable used to store imported text	No	Page
varReader	Name of an alternate variable to expose java.io.Reader	No	None

JSTL Import Tag Example:

<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<html>
<head>
<title><c:import> Tag Example</title>
</head>
<body>
<c:import var="data" url="https://www.dineshonjava.com"/>
<c:out value="${data}"/>
</body>
</html>

As you can see above, <c:import> tag imports the content of another resource specified in url attribute to the current JSP. It store the content to variable tutorial and prints it using <c:out> tag in the next line.

The <c:import> tag is similar to import action in JSP. However, <c:import> can import resources from other applications also by providing absolute path to it.
