菜鸟求助：manager cannot be resolved

[fengyun2999]

jsp页面有错
是下面navigation.jsp中的manager有错，MyEclipse提示是manager cannot be resolved
网上说manager是在banner.jsp文件中定义的，banner.jsp和navigation.jsp文件都被静态包含于main.jsp文件中，在运行时这几个文件将被合成了一个servlet。
本人是初学，如何修改

navigation.jsp代码：

<%@ page contentType="text/html; charset=gb2312"%>
<%@ page import="com.dao.ManagerDAO"%>
<%@ page import="com.actionForm.ManagerForm"%>
<%
ManagerDAO managerDAO=new ManagerDAO();
ManagerForm form1=(ManagerForm)managerDAO.query_p(manager);
int sysset1=0;
int readerset1=0;
int bookset1=0;
int borrowback1=0;
int sysquery1=0;
if(form1!=null){
	sysset1=form1.getSysset();
	readerset1=form1.getReaderset();
	bookset1=form1.getBookset();
	borrowback1=form1.getBorrowback();
	sysquery1=form1.getSysquery();
}

MyEclipse提示是manager cannot be resolved
[/Quote]

是运行时报错，还是只是在eclipse里面提示有错？
如果是后者的话可以忽略，ide还不能智能到可以判断在其他地方已经定义过并且被inlude到了一张页面，对于单个的navigation.jsp，那个manager就是没有被定义过的

[fengyun2999]

在eclipse里面提示有错
但无法运行

eclipse提示有错是正常的
无法运行是指访问main.jsp出错？什么错误信息？

启动tomcat有错误信息，以下只是一部分，

但是最终，tomcat能启动
是不是配置有问题
MyEclipse左边的包资源管理器中显示只有navigation.jsp这一个文件有红色叉号，
其它的有不少黄色叹号的

我这个系统本身是jsp+tomcatMySQL的
我想改成连SqlServer2000的，现在，SqlServer里已经有数据库了
现在缺的就是能连接上数据库

[believefym]

这个已经不是那个not resolved的错误了吧

还有，以后要贴这些exception stack trace, 记得把那个root cause贴上，那个通常容易定位错误

谢谢提醒
