I'm confused with the jstl tag libs:
I want to format a number to a currency with german style ... but everything I tried did not worked ...
I found the following example but the output is the same -.-
<%@page contentType="text/html" pageEncoding="UTF-8"%>
<%@taglib uri="http://java.sun.com/jsp/jstl/core"
prefix="c" %>
<%@taglib uri="http://java.sun.com/jsp/jstl/fmt"
prefix="fmt" %>
<html>
<head>
<title>format number</title>
</head>
<body>
<c:set var="val" value="40.52" />
<p> Currency in USA
<fmt:setLocale value="en_US"/>
<fmt:formatNumber value="${val}"
type="currency" />
</p>
<p>Currency in Germany
<fmt:setLocale value="de_DE"/>
<fmt:formatNumber value="${val}"
type="currency"/>
</p>
</body>
</html>
And thats the output:
Currency in USA $40.52
Currency in Germany $40.52
what goes wrong there ?
thanks for your help.
Awesome, by chance I got the solution to my problem:
The trick is to set the scope-parameter of the setLocale
tag to session :D and then it works ^^ sweet :)
So the correct code snippet looks like:
<c:set var="val" value="40.52" />
<p> Currency in USA
<fmt:setLocale value="en_US" scope="session"/>
<fmt:formatNumber value="${val}"
type="currency" />
</p>
<p>Currency in Germany
<fmt:setLocale value="de_DE" scope="session"/>
<fmt:formatNumber value="${val}"
type="currency"/>
Ok, I do not really know why it works, but here is some more information about my project setup:
- Spring 3 Framework (MVC, Security usw.)
- and a standard application and servlet Setup
- every thing runs in tomcat 7 so I use JSP 2.2
Hope it helps.
I had the same problem. But i think it has to do with property files. I had 2 property files, text.properties and text_sv.properties, and when the initial locale was any other than 'sv' i could change it with fmt:setLocale anywhere in my jsp-files. But when the initial locale was 'sv', fmt:setLocale did nothing. Session doen't work..
