Training material on JSF, Spring and Hibernate

Question

Hi All,
I'm new to JSF. I need some good training material on JSF, Spring and Hibernate.
I've tried lot many tutorials online, but cannot find a real good one.
Also I need to learn how we can integrate together JSF, Spring and Hibernate to build web applications.
Thanks

As far as documentation vs examples, that depends on the individual.
The Spring documentation is quite large, but Spring itself is very modular. So you can pretty much get away with reading the pieces you need when you need them and ignoring the rest.
Start with inversion of control until you feel you understand the concept. At its core, the idea is simple. Suppose you have a business class, FooService, and it needs to utilize BarService to implement its business logic. The non-Spring way would be to have the FooService class be responsible for getting an instance of BarService. The Spring way is for FooService to have a setter to be given an instance of BarService:
public class FooServiceImpl implements FooService
    private BarService barService;
    public void setBarService(BarService barService) { this.barService = barService; }
}Then the Spring container is used to "wire together" the instances:
<beans>
    <bean id="barService" class="BarServiceImpl" />
    <bean id="fooService" class="FooServiceImpl">
        <property name="barService" ref="barService" />
    </bean>
</beans>Note the advantage when using the classes in different contexts, e.g. unit testing vs production.
If I were you, I would take the sample app you have already done with JSF and try to integrate Spring into it. Move all the business logic into beans in the Spring container while keeping the view logic in the JSF layer.
