As a beginner, I first read the article in the first link and then read other articles, and I was very confused. In order to avoid the same mistake as me, I have integrated them here, hoping to help you!

The first step is to create a normal Java project

The second step is to create a web project. Right click the project name–>Add Frameworks Support

Check Web Application and click OK

Then create two folders in the web/WEB_INF directory: classes and lib

Then configure the folder path; shortcut keys ctrl + shift + Alt + s -> Modules-> Paths -> select "Use module compile out path" -> set both Outputpath and Test output path to the classes folder

Click Dependencies -> the + sign on the right -> 1 JARS or directories

Select the lib folder you just created, OK

Select Jar Directory, click OK, then save and exit

Configure Tomcat

Run -> Edit Configurations

Click ±->Tomcat Server->Local

Click Configure

Select your Tomcat path in Tomcat Home, ok

At this time, you can see a warning Warning: No artifacts marked for deployment below. Click Fix on the right and then jump to the Deployment panel.

Go back to the server panel, change On 'update' action and On frame deactivation to update classes and resources, save and exit

Test <br /> Write HelloWorld in index.jsp and run the project

Configuration successful
