Using yum installed Tomcat and JDK

I have Lucee 5 running on Amazon Linux (EC2). I would like to start using yum to install and manage Tomcat and Java. This way I could more easily update Tomcat and the JDK.

From what I can tell I would just need to install Tomcat and JDK via yum, change the environment variables in lucee_ctl to point to the new locations and move my Tomcat configuration over. Is that correct?

Is this even advisable? Should I worry about updating these myself, or is this something that the Lucee updater would take care of if/when needed?
