Resource injection issue JSF 2.2

I try to achieve resource injection for a long time but couldn't succeeded.

I use JSF 2.2, JDK 1.7. And my ide is eclipse luna.

I have a session scoped bean called UserBean and view scoped bean called SettingsBean.

I set them in faces-config.xml UserBean as session scoped and SettingsBean as view scoped with their bean name "settingsBean" and "userBean"

public class SettingsBean implements Serializable {
    private static final long serialVersionUID = 1L;

    @Inject  // I also tried @ManagedProperty but didn't work
    private UserBean userBean;

    @PostConstruct
    public void init(){         
        System.out.println(userBean.getUser().getFullName());
    }

   public UserBean getUserBean() {
        return userBean;
    }

    public void setUserBean(UserBean userBean) {
        this.userBean = userBean;
    }

}

The problem is I get userBean as null. What is the problem here? Thanks for help.

I removed ManagedBean and ViewScoped definitions in faces-config.xml for settingsBean and added them in SettingsBean.java file manually.

And added this also:

@ManagedProperty(value="#{userBean}")   
    private UserBean userBean;

So finally, it works:

    @ManagedBean
    @ViewScoped
    public class SettingsBean implements Serializable{

        private static final long serialVersionUID = 1L;

        @ManagedProperty(value="#{userBean}")   
        private UserBean userBean;  
        //...
 @PostConstruct
    public void init(){         
        System.out.println(userBean.getUser().getFullName());
    }
    public UserBean getUserBean() {
            return userBean;
        }

        public void setUserBean(UserBean userBean) {
            this.userBean = userBean;
        }
}
