body: <p>I want to integrate JSF with Spring Framework. I used <code>SpringBeanFacesELResolver</code> class on <code>faces-config.xml</code>,everythink works fine.My question is, what is the difference between <code>org.springframework.web.jsf.el.SpringBeanFacesELResolver</code> and  <code>org.springframework.web.jsf.DelegatingVariableResolver</code> ? </p>
