OmniFaces 2.x requires CDI. See also Download section of OmniFaces homepage:

OmniFaces 2.x

Required: Java 1.7, JSF 2.2, EL 2.2, Servlet 3.0 and CDI 1.1
Optional: BV 1.0

Tomcat as being a barebones JSP/Servlet container doesn't ship with CDI out the box. It's only available in full fledged Java EE containers like WildFly and TomEE. The same applies to JSF (and JSTL), by the way, you'd have to manually install it in Tomcat.

You've 2 options:

Replace Tomcat by TomEE or any other Java EE container.
Manually install CDI in Tomcat.
