JSTL Core <c:import> Tag
Advertisements
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 |
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="http://www.tutorialspoint.com"/>
<c:out value="${data}"/>
</body>
</html>
Above example would fetch complete content from tutorialspoint.com/index.htm and would store in variable data which will be printed eventually. Try it yourself.
