In order to better manage tomcat servers, we usually A user administrator will be added to tomcat so that you can log in to view the published project. For beginners, you need to be familiar with the principle of tomcat project release.
Tomcat is a core project in the Jakarta project of the Apache Software Foundation, developed by Apache, Sun, and other companies and individuals.

Step 4: The server does not report an error, indicating that the project is successfully published. Just put the project you want to send to the webapps directory in tomcat, and the tomcat server will automatically publish the project. Now the Mail project has been released online.
Step 5: Open your browser. Here I use Google Chrome to explain: access tomcat home page: If your tomcat can access the home page, then your tomcat configuration is successful.
