Once you login via ssh to your cPanel dedicated server, the first thing you will need to do is stop tomcat:
/usr/sbin/stoptomcat
Next, use the following commands:
rm -f /usr/sbin/starttomcat
rm -f /usr/sbin/startomcat
rm -f /usr/sbin/stoptomcat
Remove all mod_jk lines from your httpd.conf, including addmodule, loadmodule and include line.
