Pieter, Have you set up Spring's ContextLoaderListener (a Servlet listener that initiates your Spring context) and registered the Spring SpringComponentInjector as a Component instantiaition listener [1]?
Your idea to instigate injection in the super classes constructor is fine as "this" will be the concrete subclass that you are instantiating - make sure the right super constructor is called in all places you want injection to take place, and also that you are not initialising the sub-classes injected properties as that would take place after the super class is initialised undoing what the super class constructor has done. Finally, in a case like this, get the simplest possible scenario working first (here, try injecting into the subclass directly) to show you have everything set up correctly and then try the conceptually slightly more complex solution of pushing-up the responsibility to instigate injection for all your "models" into their common, abstract superclass. Also, notice that this injector goes straight to your fields, even if they're private, so your setters not being called alone does not mean injection has not succeeded Does that make sense?
