Solutions to Tomcat unable to display the page: 1. Check the Tomcat configuration file; 2. Check port conflicts; 3. Check project deployment; 4. Check browser settings; 5. Check network connection; 6. View logs file; 7. Restart the Tomcat server; 8. Check the firewall and anti-virus software settings. Detailed introduction: 1. Check the Tomcat configuration file to ensure that the configuration items in the Tomcat configuration file are correct. Errors in the configuration file may cause Tomcat to fail to start normally or fail to display the page, etc.

If Tomcat cannot display the page, it may be caused by a variety of reasons, including configuration file errors, port conflicts, project deployment issues, etc. The following are some steps and methods to solve the problem that Tomcat cannot display:

1. Check the Tomcat configuration file: Make sure that the configuration items in the Tomcat configuration file (such as server.xml) are correct. Errors in the configuration file may cause Tomcat to fail to start properly or fail to display the page. When checking the configuration file, you need to pay attention to the syntax and format of the configuration file, and refer to Tomcat's official documentation for repairs.

2. Check port conflicts: If the port used by Tomcat is occupied by other programs, the page will not be displayed. The solution is to modify the port number of Tomcat or stop the program occupying the port. The port conflict problem can be solved by modifying the port number in the Tomcat configuration file (such as server.xml).

3. Check project deployment: Ensure that the project has been correctly deployed to the Tomcat server. If the project is not deployed correctly, it may result in the page not being displayed. When checking project deployment, you need to pay attention to the project's directory structure and configuration files to ensure that the project can be correctly identified and run.

4. Check the browser settings: Check the browser settings to ensure that it allows loading pages from the Tomcat server. Sometimes the browser's security settings or proxy settings may prevent pages from the Tomcat server from loading.

5. Check the network connection: Make sure the network connection is normal and the Tomcat server can access the Internet normally. If there is a problem with your network connection, it may prevent the page from loading.

6. Check the log file: Check the Tomcat log file (such as catalina.out) to understand the server running status and abnormal information. The log file may contain error information about the page that cannot be displayed, which can help locate the problem.

7. Restart the Tomcat server: Sometimes restarting the Tomcat server can solve the problem of being unable to display the page. You can try restarting the server and accessing the page again to see if it can be displayed normally.

8. Check the firewall and anti-virus software settings: Sometimes the firewall or anti-virus software may block the communication between the Tomcat server and the browser, resulting in the page being unable to be displayed. You need to check the settings of your firewall and anti-virus software to make sure they allow communication between the Tomcat server and the browser.

In short, solving the problem that Tomcat cannot display the page requires comprehensive consideration of a variety of factors, including configuration file errors, port conflicts, project deployment, browser settings, network connections, log files, firewall and anti-virus software settings, etc. In the process of solving the problem of being unable to display, you need to pay attention to maintaining the consistency of character encoding between the system and the application to avoid other garbled characters. At the same time, it is also necessary to regularly check the status of the server hardware and promptly discover and repair hardware faults to ensure the normal operation of Tomcat.
