First, we want to know our own locale，how to display the locale in a JSTL?
<c:out value="${pageContext.request.locale.language}"/>
I'm confused with the jstl tag libs:
I want to format a number to a currency with german style
<%@page contentType="text/html" pageEncoding="UTF-8"%> <%@taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %> <%@taglib uri="http://java.sun.com/jsp/jstl/fmt" prefix="fmt" %> <html> <head> <title>format number</title> </head> <body> <c:set var="val" value="40.52" /> <p> Currency in USA <fmt:setLocale value="en_US"scope="session"/><fmt:formatNumber value="${val}" type="currency" /> </p> <p>Currency in Germany <fmt:setLocale value="de_DE"scope="session"/><fmt:formatNumber value="${val}" type="currency"/> </p> </body> </html>
And thats the output:
Currency in USA $40.52
Currency in Germany 40,52 €

I am using fmt:formatNumber to format currency in JSTL, it will display negative currency in ($100) format, if you want to make it display negative currency in negative format instead of ($100). I would suggest:
<c:set
var="val" value="46563746375"/>
<fmt:formatNumber
value="${val}"
pattern="###.###E0"/>
