Re: Platform wide guideline for build-in annotation literals?

Sorry, that's not what I meant ;)

What I meant was that each annotation should of course stay within their respective spec. I.e. @Transactional should of course stay in JTA.

But the annotation literal support should be somewhat mandated by the umbrella spec, so that all specs provide those for their annotations (where applicable) and all specs do it in the same way.

For instance, CDI now has:

RequestScoped requestScopedLiteral = RequestScoped.Literal.INSTANCE;

So JSF should get:

ViewScoped viewScopedLiteral = ViewScoped.Literal.INSTANCE;

And not say:

ViewScoped viewScopedLiteral = ViewScoped.getAnnotation();

or 

ViewScoped viewScopedLiteral = ViewScoped.of(ViewScoped.class);

or ...

ViewScoped should of course stay within JSF and nothing should ever move to the umbrella spec. The umbrella spec should only establish a rule saying that annotation literals are to be done via [annotation class].Literal.INSTANCE;

Hope it's more clear now ;)

Kind regards,
Arjan Tijms
