In Spring 2.5 framework we can annotate classes with @Component, this automatically create a managed spring bean, this
is very usefull in JSF projects when we add:

<variable-resolver>
      org.springframework.web.jsf.DelegatingVariableResolver
</variable-resolver>

To faces-config.xml, we can use @Component and any spring bean in JSF pages using EL. For example

@Component("myBean")
@Scope("request")
public void MyBean{
      public String someAction(){
              return "action"
      }
}

In any jsf web file we can use EL to invoke that action

<h:commandButton action="#{myBean.someAction}/>

Its will be very nice that in jsf files we can get a code completion for this kind of beans..
