Internationalization Tag Library in JSP
What is Internationalization Tag Library in JSP?
Explanation
Internationalization Tag Library or 118N Tag library lists the tags that confirm the client locale settings for formatting and parsing client sensitive data like currency, date, etc in a locallized or customized manner. The following table lists all the tags that confirm to 118N standards and is used with a prefix "fmt".
<%@ taglib uri="http://java.sun.com/jsp/jstl/fmt" prefix="fmt" %>
<%@ taglib uri="http://java.sun.com/jsp/jstl/fmt"
prefix="fmt" %>
<p>Convert the number 14.3 with 4 decimal places</p>
Formatting: <fmt:formatNumber value="123.4" type="NUMBER"
minFractionDigits="4" /> Result :
Convert the number 14.3 to have 4 decimal places
Formatting: 123.4000
In the above example we have used the 118N tag to add "4" decimal places to the number given.
<%@ taglib uri="http://java.sun.com/jsp/jstl/fmt" prefix="fmt"%>
<jsp:useBean id="dat" class="java.util.Date" />
<fmt:formatDate value="${dat}" type="time" /> Result :
1:44:40 PM
In the above we have used the "<:jsp:useBean/>" tag to include the java date class, using the format tag attribute "type" the time alone is displayed.
