Get all instances of Bean JSF

I was wondering if it is possible to retrieve ALL instances of a given Bean from the FacesContext. This includes that beans might be session scoped.

Or do I have to register them somewhere in instatiating and retrieve them again later?

The method from which I want to clal this funktionality will be triggered by a @Schedule and is for clearing all caches that are held somewhere in the application

Thanks in advance :)

Yes, you have to.

@PostConstruct
public void init() {
    allBeans.add(this);
}

@PreDestroy
public void destroy() {
    allBeans.remove(this);
}

allBeans can be an injected application scoped bean.
