Spring 3 and JSF 2 integration issue

[greengold]

hi guys!
As title is saying I want to integrate Spring with JSF and aslo with Spring Security...
The problem that Im having now is that I can't access springs @Component beans form JSF pages even though I have org.springframework.web.jsf.el.SpringBeanFacesELRe solver declared in faces-config.xml.
Here is my project snippet:

web.xml:

configuration java class:

    @Bean
    ViewResolver viewResolver() {
        InternalResourceViewResolver resolver = new InternalResourceViewResolver();
        resolver.setPrefix("WEB-INF/jsp/");
        resolver.setSuffix(".jsp");
        return resolver;  
    }   
}

finally presentation layer:

<?xml version='1.0' encoding='UTF-8' ?>

      xmlns:f="http://java.sun.com/jsf/core">
    <h:head>
        <title>Facelet Title</title>
    </h:head>
    <h:body>
        Hello from Facelets
        
        <div>
            <p:calendar autocomplete="true" label="kalendar"></p:calendar>
        </div>
        
        <div>
            <h:outputLabel value="#{testBean.text}" rendered="true"/>
        </div>
    </h:body>
</html>

TestBean class:

@Component("testBean")
@Scope(value="request")
public class TestBean {
    
    String text = "spring with jsf is working!";

    public TestBean() {
    }

    public String getText() {
        return text;
    }
}

Weird is that when I have testBean declared as bean in xml configm its working..
Also I wanted to ask why this app is not working when <context:component-scan base-package="sk.insdata.webmaven" /> is declared in aplicationContext.xml instead of dispatcher-servlet.xml?

Thanks for advices!

SpringMVC and JSF(2) don't really mix use either one not both...

JSF can only access beans loaded by the ContextLoaderListener (this contains nothing in your case) not the beans loaded by a DispatcherServlet.

[greengold]

not both? And why it is working when beans are declared in xml? see tutorial, perhaps: http://papweb.wordpress.com/2011/07/...-2-and-tomcat/

[Marten Deinum]

Because they load the same applicationcontext twice (once in the contextloaderlistener and once in the DispatcherServlet). Both the ContextLoaderListener and DispatcherServlet load the file applicationContext.xml.

The FacesServlet doesn't know about other servlets and as such cannot access its environment so that way it is impossible to get access to variables declared in that servlet. The ApplicationContext is just a variable stored in the servletcontext.
