Masz elementy dwóch różnych konterów: kontenera Spring i kontenera JSF. Nie powinieneś jednocześnie rejestrować tego jako service spring i jsf managed bean. To obiekt zarządzany przez dwa różne kontenery (skomplikowane i może się zepsuć).

Ogarnij jak działa facesELResolver w faces-config.xml:

    <application>
        <el-resolver>org.springframework.web.jsf.el.SpringBeanFacesELResolver</el-resolver>
    </application>

Service springowy wstrzyknij jako JSF Managed Bean (za pomocą EL, pamiętaj o setterze):
http://www.mkyong.com/jsf2/injecting-managed-beans-in-jsf-2-0/

Jeśli nie musisz się meczyć ze Springiem radzę migrować to do CDI/JEE jeśli chcesz JSF (mniej problemów).

Czyli mieszanie springa z JSF nie jest dobrym pomysłem. A w jaki sposób najłatwiej połącze JSF z baza danych. Poszukuje jakiegos tutka lub gotowego szkieletu żebym podłapał jak działa JSF z JPA (bo pewnie skoro standard JavaEE to JPA bedzie najlepsza opcja ?)

Możesz użyć EJB3 i JPA2. Działa bardzo podobnie jak repozytorium springowe z JPA. Korzyść taka, że masz ułatwione wykorzystanie CDI w JSF. Jeśli chcesz możesz używać legacy JSF Managed Beans i wstrzykiwać springowe repozytorium tak jak wyżej napisałem (przez EL). Jest wiele sposobów na osiągniecie tego samego.

JSF Managed Bean może być lepszym wyborem jak nie masz serwera aplikacyjnego (trzeba coś na szybko zrobić na Tomcat / Jetty).
