{quote} By not providing a scope bigger than 1 per WAR, we DO NOT HAVE THOSE AFOREMENTIONED PROBLEMS IN CDI. {quote}
OK, assume there is a shared @RequestScoped bean R in the shared library injected both into a Servlet in your web app and into the MailService in the shared lib. No alternatives nor specialization this time. What you say is that assuming the Servlet invokes MailService, the Servlet would operate on a different instance of the same R bean than the MailService? In the same call stack during processing of the single same request? How is that consistent? Maybe we could do a poll if this is what people want ;-) This is not CDI.

{quote} on which part? On the 'unusable' or the 'multiple contextual instances per Injection Point for the same call stack'? {quote}
I disagree that it is unusable.

> Since @ApplicationScoped currently is defined in 6.5.2 as to be 'like in the Servlet specification' this means that you will get a new instance for every WebApplication (WAR file).
> There is currently no specified CDI scope for providing a single shared instance for a whole EAR.
> We could (ab-)use @Singleton for that, but this is currently not well defined at all.
> Alternatively we could introduce an own new annotation like @EnterpriseScoped or likes.
