Tomcat 404错误：原始服务器没有找到目标资源的当前表示，或者不愿意透露该目录的存在 [英] Tomcat 404 error: The origin server did not find a current representation for the target resource or is not willing to disclose that one exists

问题描述

我遵循了o7计划的教程，并被困在第6步：

o7planning.org/en/10169/java-servlet-tutorial

这只是一个简单的项目，显示HelloWorld，但由于某些原因我不断得到404错误。详细信息：

-
HTTP状态404 - 未找到

类型状态报告

消息/ ServletTutorial /

描述源服务器没有找到目标资源的当前表示，或者不愿意披露一个存在。

更新更新：项目可能有多个web.xml文件。

如果

src / main / webapp / WEB-INF

中的另一个web.xml

然后，您可能需要添加另一个索引（此时index.jsp）到

src / main / webapp / WEB-INF / pages /

I've followed the tutorial on o7planning and got stuck in step 6:

o7planning.org/en/10169/java-servlet-tutorial

It's just a simple project that show HelloWorld but for some reason I keep getting 404 error. Detail:

-- HTTP Status 404 – Not Found

Type Status Report

Message /ServletTutorial/

Description The origin server did not find a current representation for the target resource or is not willing to disclose that one exists.

404 page

However the Tomcat welcome page showing properly.

Here solutions that I've tried so far (and they are NOT working):

Right-click project -> properties -> Project Facets -> Runtimes -> checked "Apache Tomcat v9.0" -> Apply -> finish.

Server tab -> Right-click "Tomcat v9.0..." -> properties -> switch location -> Choose "Use tomcat installation" on "Server locations" panel.

解决方案

Problem solved, I've not added the index.html. Which is point out in the web.xml

Update:

More update: a project may have more than one "web.xml" file.

if there are another "web.xml" in

src/main/webapp/WEB-INF

Then you might need to add another index (this time index.jsp) to

src/main/webapp/WEB-INF/pages/
