Confirm whether the name and value of the environment variable are correct, whether the path exists, etc. You can check whether the environment variable settings are correctly configured in the system properties.

2. Restart the computer: Sometimes you need to restart the computer after modifying the environment variables to take effect. Try restarting your computer and check again whether the environment variables take effect.

3. Check the Tomcat installation directory: Make sure the path of the Tomcat installation directory is correct and has not been modified. If the installation directory has been modified, the values ​​of the environment variables need to be updated accordingly.

4. Check the Tomcat configuration file: Check whether the configuration file in the Tomcat directory is configured correctly, such as server.xml, etc. Make sure there are no errors or omissions in the configuration file and that it matches the settings of the environment variables.

5. Check system permissions: Check whether the current user has sufficient permissions to access the Tomcat directory and its subdirectories. Sometimes, environment variables cannot be configured correctly due to permission issues. Make sure the current user has appropriate read, write, and execute permissions.

6. Reinstall Tomcat: If the above steps do not solve the problem, you can consider reinstalling Tomcat. Before reinstalling, please back up important configuration files and data, then follow the correct steps to reinstall Tomcat and ensure that the environment variables are correctly configured.

7. Check the log file: Check the Tomcat log file to see if there are any errors or warnings related to environment variables. This helps diagnose the source of the problem and find a solution.

9. Check the port number: Check whether Tomcat is bound to the correct port number. If the port number is occupied or configured incorrectly, Tomcat will not start or run normally. Make sure the port number in the Tomcat configuration file is set correctly and is not occupied by other applications.

10. Update the operating system: Sometimes, the unsuccessful configuration of environment variables may be related to the operating system version or configuration. Try updating the operating system to the latest version and make sure it is compatible with the version of Tomcat.

Tomcat requires a Java environment to run, so please ensure that the JDK is installed and configured correctly.

12. Check the network connection: If Tomcat needs to access other services through the network connection, please check whether the network connection is normal. Network problems may prevent Tomcat from starting or running properly.

13. Reference documents and communities: Check Tomcat's official documentation or related communities to learn more details about environment variable configuration. Occasionally, other users may have encountered similar problems and found solutions.

14. Use a script to start Tomcat: Try to use a script to start Tomcat, such as using startup.bat or startup.sh file. This ensures that environment variables are set correctly on startup.

Through the above methods, you should be able to solve the problem of unsuccessful configuration of Tomcat environment variables. If the problem persists, further inspection of the system and application configuration may be required to find the root cause and take appropriate action.
