Question

我正在使用eclipse和jslt

我添加了jslt jar文件并导入了jslt“C”和“fmt”。但我仍然收到fmt的错误。第40行是这样的：

value="${peopleList[1].salary}"

下面是我得到的错误：

这是代码：

pageEncoding="ISO-8859-1"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>

<body>
<jsp:useBean id="people" scope="session" class="MyPackage.Bean02">
</jsp:useBean>

          <fmt:formatNumber type="currency"
         value="${peopleList[i].salary}"
         minFractionDigits="2"
         maxFractionDigits="2"/>
...

Answer 1

fmt的taglib导入错误。这是旧版本。将其更改为

<%@ taglib uri="http://java.sun.com/jsp/jstl/fmt" prefix="fmt" %>

错误或apache jasper jasperexception
