问题描述
我有jstl代码，它由maven好建立...但Eclipse有编译错误未知标签（c：foreach）。
代码在这里：
<％@ page language =javacontentType =text / html; charset = ISO-8859-1
pageEncoding =ISO-8859-1％>
<％@ taglib uri =http://java.sun.com/jsp/jstl/coreprefix =c％>
<！DOCTYPE html PUBLIC - // W3C // DTD HTML 4.01 Transitional // ENhttp://www.w3.org/TR/html4/loose.dtd\">
< html>
< head>
< meta http-equiv =Content-Typecontent =text / html; charset = ISO-8859-1>
< title>在此插入标题< / title>
< / head>
< body>
< ul>
< c：forEach items =$ {listOfMyFriends}var =friend>
< c：out value =$ {friend}>< / c：out>
< / c：forEach>
< / ul>
< / body>
< / html>
有人可以帮我避免这个提议吗？

解决方案
在Eclipse中发生了同样的事情。我删除了您的代码中出现的<％@和taglib之间的空白区域。
所以现在看起来像这样，并且警告消失了： p>
I have jstl code and it builds by maven well... But Eclipse had compilation error "Unknown tag (c:foreach)."
code are here:
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
<ul>
<c:forEach items="${listOfMyFriends}" var="friend">
<c:out value="${friend}"></c:out>
</c:forEach>
</ul>
</body>
</html>
could someone help me to avoid this promlem?

解决方案
Same thing was happening to me in Eclipse. It dissapeared after I deleted the white space between <%@ and taglib that appears in your code.
So now it appears like this and the warning is gone:
