同学把配置文件改为下面这个后再试下~

	</servlet>
	<servlet-mapping>
		<servlet-name>logon</servlet-name>
		<url-pattern>/denglu.do</url-pattern>
	</servlet-mapping>
</web-app>

另外，同学运行存在问题的项目，其目录结构是不正确的，lib文件夹和classes文件夹应该都是存在于WEB-INF目录下的，同学如果运行还有问题，建议先把目录结构调整正确。

祝学习愉快！

    最后还是感觉工程出了什么问题，新建一个工程重写代码没什么问题了，就这样吧，还是多谢各位老师一周一直跟进我的问题。

同学你好，看你上面贴出来的内容目录，classes文件夹应该是在WEB-INF目录下的，建议同学把classes文件夹移动到WEB-INF目录下再试下~如果还有问题，建议同学把你的web.xml贴一下，方便我们帮助你盘查解决问题；设立问答区的好处就是方便老师追踪同学的问题，如果发邮箱可能会出现遗漏情况呢~ 因此同学如果还有有问题的话，可以将关键的配置文件web.xml贴出来，我们帮助你分析解决。祝学习愉快！

    其实第一张图的工程是我后来建的，没有问题了（当然这里的代码跳掉了中间的几节课），就是我一开始按照视频里一步步写下来的第一个工程出了问题。 这个工程的web.xml是： <?xml version="1.0" encoding="UTF-8"?> <web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd" version="4.0"> <servlet> <servlet-name>login</servlet-name> <jsp-file>/login.jsp</jsp-file> <init-param> <param-name>age</param-name> <param-value>100</param-value> </init-param> </servlet> <servlet-mapping> <servlet-name>login</servlet-name> <url-pattern>denglu.do</url-pattern> </servlet-mapping> </web-app> 其实也是照着视频写的。

现在是这样：

我重新把代码写了一遍，运行没问题了，没有报错。

http://img1.sycdn.imooc.com//climg/5b6d66c30001906307840888.jpg


我之前出问题的时候，项目除了示例代码以外，自己也加上了作业代码，结果出现了问题。

http://img1.sycdn.imooc.com//climg/5b6d66ca0001ee3408100968.jpg


这是什么原因？要我帖代码倒可以但是这么多文件，不能直接上传附件吗？

    不能上传附件的，如果同学找不到错误原因，可以新建一个问答，并把代码粘贴上来，注意贴jsp代码的时候要标注页面的名称，方便老师为你调试，并帮助你解答问题，祝学习愉快~

贴一下web.xml文件，看看是否配置有问题，另外也可以把你的代码都贴出来，我们运行看看是代码本身的问题，还是环境问题。你也可以重新建一个web工程，只有一个jsp文件，看看是否还会发生类似的问题。祝学习愉快！

    我又看了下，加入4-5这一章的代码之前都是没有问题的，正常部署正常运行。但是我就在源代码上加了new throw();，errorpage，新建了error.jsp，就不能运行了，是不是idea做错误处理需要额外的配置？
    2018-08-05 12:47:15
  • 一叶知秋519 回复 提问者 风岚醉 #2
    同学去掉error.jsp页面以后是可以正常运行的？ 建议同学把你的代码贴一下，我们运行试一下~
    2018-08-06 09:54:14
提问者 风岚醉 2018-08-03 19:06:46

还有，我后来把新加的error页面删了，新代码注释了，还是在部署上出了问题。
