Question

I have a JSF 2.0 bean:

@ManagedBean
@SessionScoped
public class LoginBean implements Serializable
{
    protected String name;

    public String getName()
    {
        return name;
    }

    //....
}

I have a Spring 3.0 bean:

@Repository
public class Logins
{
    @ManagedProperty(value="#{loginBean}")
    protected LoginBean loginBean;

    public void recordLogin()
    {
         //... record in db that loginBean.getName() just logged in
    }
}

This code doesn’t work, Logins.loginBean is never set.

Alternatively (its the same question, simplified) – would the following code ever work?

@Repository
public class SpringBean
{
    @ManagedProperty(value="#{session.id}")
    protected String id;

    //....
}

The ContextLoaderListener and RequestLoaderListener are declared in web.xml.

Is it possible at all to inject a JSF bean into a Spring bean? (Without using yet another extra framework)

Or should I rather convert my JSF bean into a Spring bean and use the DelegatingVariableResolver trick in faces-config.xml? I have already tested this with a test Spring bean, and it works.

Using JSF annotations in spring-managed beans doesn’t work. And it shouldn’t – you should not inject things from the web layer in the other layers. It should be the other way around – inject spring services (or repositories) into web components (jsf managed beans), and invoke methods on them, passing the managed bean properties as arguments
