In my opinion, Spring and JSF - both could be used just fine. It, of course, mostly depends on your requirements and preferences of using those frameworks.

Spring - it has very nice ways of transactions management, dependency injection, security and many other features, however - plain JSF does not provide this kind of features out of the box, but JSF has very nice way of rendering views. So these features from both frameworks mixed up together could result in simplicity. JSF has a variety of it's frameworks which are built on it, like:

• Primefaces
• RichFaces
• IceFaces

In my opinion, you could simplify your views development, if you had been using JSF. JSF has ManagedBean(s), which depending on your configuration serves your requests, like Spring controllers does.

Actual configuration is pretty straight forward. You need to have:

faces-config.xml file which contains SpringBeanFacesELResolver:

    
        org.springframework.web.jsf.el.SpringBeanFacesELResolver
    

    
        
    

Spring applicationCotext.xml file. Usual spring config, nothing JSF specific.

Your web.xml which should look something like this:

    

    
        contextConfigLocation
        WEB-INF/applicationContext.xml
    

    
        javax.faces.PROJECT_STAGE
        Production
    

    
        org.springframework.web.context.ContextLoaderListener
    
    
        org.springframework.web.context.request.RequestContextListener
    

    
        Faces Servlet
        javax.faces.webapp.FacesServlet
        1
    
    
        Faces Servlet
        *.xhtml
    

    

The most pretty cool thing in JSF is View Scope, which would be lost by default, if you had been using JSF with Spring, but definitely you don't want to lose it. This explains how to make View Scope work in JSF and Spring integration.

If I would be building some application from scratch, I would choose these two frameworks and integrate them together, but this is just my opinion. Hope this clears some things for you.
