不知道为什么本来能够通过的程序全都出错了  上面是抛出的异常  原因？？？
是不是  因为导入的工程全都是一个名字tomcat 有了相应的处理
发现在Tomcat里边Olympic已经被编译成Olympic.eclipse.bak运行这个可以出来结果


又错误
这又是什麽原因呢    为什么？后不运行了

在做QueryStuffTimeRecord 时  出现这种情况  光能出现这句话 “对不起，没有你要浏览的条目”  都觉得改对了  原因是没有把信息送回给页面啊
HttpSession session = request.getSession();
session.setAttribute("stuffTimeRecordList", stuffTimeRecordList);

[e-mail]


在修改和增加混合得页面中  ，为什么attendance是null呢
别的都没有出错是因为你的jsp页面中的问题  下拉列表框的表示应该是
<html:select>
<html:option></html:option>
</html:select>
都丢掉html了
不符合Struts格式了

不知道怎么做的
1 是怎样自动生成的 数据库 类 的
2 是怎样让Log4j控制查看用户的输入信息的
3  多模块开发的要求是怎样又创建的 Struts-config.xml
Web.xml  中是不是要
<param-name> congfig/m10config</param-name>
<param-value>struts-configm10.xml</param-value>

新建 —— File——Struts-config.xml——后出现的标志和已存在的不一样

HttpSession session 
Request.getAttribute
Jsp 的用法
