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" %>

	
	<%
		String s = "My New Tag Test!";
		request.setAttribute("name", s);
	%>	
		Test El supported TAG:
		${name}/>
	

 

添加引号后问题解决了：

 

<%@ page language="java" %>
<%@ taglib uri="/WEB-INF/tlds/diego.tld" prefix="diego" %>

	
	<%
		String s = "My New Tag Test!";
		request.setAttribute("name", s);
	%>	
		Test El supported TAG:
		"${name}"/>
