出现这个错误？javax.servlet.jsp.JspException: Cannot find bean personList in any scope，其实很简单 

严重: Servlet.service() for servlet jsp threw exception

 出现这个错误，找不到解决方法，我也遇到了，其实我是在参考java web整合开发

代码明明都正确，但是为什么listPerson.jsp就是运行不出来，一点击就出错呢？

 

原因很简单，首先应该运行的页面时addPerson.jsp

 

书中没有addPersonList.jsp这个页面，需要自己再添加

 

 

页面参考代码：

<%@ page language="java" pageEncoding="UTF-8"%>
<%@ taglib uri="http://jakarta.apache.org/struts/tags-bean" prefix="bean"%> 
<%@ taglib uri="http://jakarta.apache.org/struts/tags-html" prefix="html"%>
 
<html> 
	<head>
		<title>JSP for PersonForm form</title>
	</head>
	<body>
		添加成功。<a href="person.do?action=list">返回人员列表</a>
	</body>
</html>
