In IDEA

i followed the jetbrains offical toturial to use tomcat but always fail, even cannot be available to tomcat home page

directly

i tried to launch tomcat without IDEA but still failed, this time i can see the home page, but i have no access to samples of tomcat

1. Use tomcat in IDEA

It didn’t work at first, and then I read the official jetbrains tutorial [https://www.jetbrains.com/guide/java/tutorials/working-with-apache-tomcat/]
Followed step by step. At first he said the error was normal, but later he solved it but I still haven’t.
Later I found a few more blogs and followed them, but it was still useless. After reading the logs, everything was normal, but the homepage could not be opened in the browser.

2. Open tomcat directly

• It is slightly better than using IDEA. You can see the tomcat homepage, but its samples cannot be opened, the same 404
• Tried to use maven to package the project into war and put it in tomcat’s webapps directory, but still got the message “The requested resource [/xxxxxx/] is not available”
