http status 404

IE错误如下：

HTTP Status 404 - /streetManager/index.jsp

type Status report

message /streetManager/index.jsp

description The requested resource (/streetManager/index.jsp) is not available.

Apache Tomcat/6.0.10

百度下：

HTTP Status 404 - //

type Status report

message //

description The requested resource (//) is not available.

Apache Tomcat/6.0.18

在百度搜索了，得到了提示：

原因：servlet没有配置正确 ，查看web.xml确认正确,以及自己的请求路径正确。

解决：在MyEclipse中点开web.xml查找了n遍，web.xml配置的没有一点错误。然后到程序中查找各个请求的路径，也没有错误。查找了好半天，终于找到了，原来是我在MyEclipse重构的时候复制web.xml的时候,不小心把它复制到了WEB-INF中的lib文件夹中了。当时没有察觉，浪费了我好多时间。把web.xml拖出来放到WEB-INF中就解决了。

HTTP Status 404

在IE中提示“404”错误有以下三种情况

I．未部署Web应用

II．URL输入错误

排错方法：

首先，查看URL的IP地址和端口号是否书写正确。

其次，查看上下文路径是否正确 Project--------Properties------MyElipse-----Web-----

Web Context-root检查这个路径名称是否书写正确。

最后，检查一下文件名称是否书写正确。

III．目录不能被引用

排错方法：

在 Eclipse的“包资源管理器(Package Explorer)”检查文件存放的位置。由于META-INF

WEB-INF文件夹下的内容无法对外发布，所以，如果你引用了带这两个目录的文件，肯定是不允许。例如：http://localhost:8080/guestbook/WEB-INF/index.html就是错误的

文件位置存放错误。

解决办法：查看下MyEclipse报错吧..

看来是applicationContext-dailyOfficeBeans.xml文件配置问题喽~~打开看下

呃…问题出在…感觉没错..⊙﹏⊙b汗

继续找其他文件…struts-config.xml

无语中…注释写错了。

继续找问题….Daoimpl.java文件没有import…

import com.common.HibernateSessionFactory;
import com.dailyOffice.dao.daoI.DailyOfficeDaoI;

重新发布成功。

怎么MyEclipse有时候不会提示出错…写代码时那个小红叉有时候从不出现…重启后才有…

查看下有什么红叉问题没有解决
