How to resolve .htaccess 'SetEnv' for tomcat

Hi all, I am trying to host my java website and having a bit of trouble. I followed this tutorial: How to Deploy Java Applications - cPanel Knowledge Base - cPanel Documentation But I am receiving and Internal Server Error when trying to access the domain from the web. The message in the Error logs say: /home/myusername/public_html/.htaccess: Invalid command 'SetEnv', perhaps misspelled or defined by a module not included in the server configuration In my .htaccess file is: SetHandler jakarta-servlet SetEnv JK_WORKER_NAME ajp13 Could someone shed some light on the code that would fix this error?
