SetLocale did not work in jsp site to format currency in german

currency-formatting, jsp-tags, jstl, spring-mvc

Solution

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.

Problem

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.
