很简单的一个错误， /mynewtag.jsp(10,22) quote symbol expected
直接说明白了，mynewtag.jsp文件中第10行缺少引号……
原代码如下：
<%@ page language="java" %>
<%@ taglib uri="/WEB-INF/tlds/diego.tld" prefix="diego" %>
<html>
<body bgcolor="#FFFFFF">
<%
String s = "My New Tag Test!";
request.setAttribute("name", s);
%>
Test El supported TAG:
<diego:newout name=${name}/>
</body>
</html>
添加引号后问题解决了：
<%@ page language="java" %>
<%@ taglib uri="/WEB-INF/tlds/diego.tld" prefix="diego" %>
<html>
<body bgcolor="#FFFFFF">
<%
String s = "My New Tag Test!";
request.setAttribute("name", s);
%>
Test El supported TAG:
<diego:newout name="${name}"/>
</body>
</html>
