Spring @Autowired of @Service classes works on Tomcat but not Resin

I have a 100% working solution in Tomcat 8.0.20 packaged as a WAR using Spring restful services and spring core libraries.

When I take the same WAR and drop it into Resin 4.0.36 (and also 4.0.43) my @Autowired @Services are not recognized whatsoever.

This leads me to believe that there is an environmental difference between Tomcat and Resin. Do I need to set some property or reference something explicitly to make the WAR work on Resin?
