奇怪的问题

Question

WEB-INF\classes目录JavaBean必须打包

Answer 1

WEB-INF\classes\yourpackage\xxx.class
usebean的时候记得也要yourpackage.xxx

Answer 2

WEB-INF\classes\yourpackage\xxx.class
但是还是找不到怎么办？具体情况这样exam.jsp文件放在jswdk下的webpages目录下
exam.jsp中使用bean情况
<%@ page language="java" contentType="text/html;charset=GB2312" buffer="none"%>
<jsp:useBean id="exam" scope="session" class="ch8.exam"/>
＋＋＋＋＋＋＋＋＋＋＋＋＋＋＋＋＋＋＋＋＋＋＋＋＋＋＋＋＋＋＋＋＋＋＋＋＋
java文件如下
按要求放在jswdk>webpages>web_inf>classes
下package ch8;
public class exam
{}
确认exam无错误
执行返回错误为
