requires that an attribute name is preceded by whitespace异常总结

JSPApacheHTML 
阅读更多

在tomcat7.0下，会报一个异常：

org.apache.jasper.JasperException: /head.jsp(1,84) The JSP specification requires that an attribute name is preceded by whitespace

head.jsp我是用<jsp:include page="head.jsp" flush="true"/>引入的，在tomcat6.0的环境下，不会报以上的异常，但在tomcat7.0会报这个异常，后来，仔细查了一下head.jsp文件第一行。原来我真的漏了一个空格，

<%@ page language="java" contentType="text/html; charset=UTF-8"pageEncoding="UTF-8"%>

在pageEncoding之前漏了一个空格。改正，重新运行，ok了！

<%@ page contentType="text/html;charset=GB2312"%>
<%@ taglib tagdir="/WEB-INF/tags"prefix="beijing"%>
<%@ taglib tagdir="/WEB-INF/tags/geng"prefix="dalian"%>
<html><body bgcolor=cyan>
<h3>以下是调用tag文件的效果：</h3>
<beijing:AddSum/>
<h3>以下是调用tag文件的效果：</h3>
<dalian:EvenSum/>
</body></html>
