tomcat OCF resource-agent also supports redirecting to systemd:
<parameter name="force_systemd" unique="0" required="0"><longdesc lang="en">
Force use of systemd when available.
</longdesc>
<shortdesc lang="en">Force use of systemd when available</shortdesc>
<content type="string" default="$OCF_RESKEY_force_systemd_default" />
</parameter>
If this does not work for you, or you have valid use case where direct tomcat management works but systemd-based does not, you should open bug report.
