Re: [webbeans-dev] Spec Conflicts Between JSR-299, JSR-318

Hi guys. In discussing WebBeans/EJB integration with Pete this week we came across a few issues I'd like to hash out. *Guiding Principles* The points below are based on my view of the following bullets; please correct if they're inaccurate. * JSR-299 implementations are treated the same as any client of EJB; they use/consume EJB as one of the target component models. * A mechanism EJB makes available to JSR-299 should be available to everyone. ---- 1) EJB does not define an endpoint for SFSB removal outside business/component method @Remove/remove() and timeout JSR-299 PR2 6.5 - "When the destroy() method is called, the container removes the stateful session bean. The @PreDestroy callback must be invoked by the container." JSR-318 PFD2 4.6 - "When the client calls a business method of the bean that has been designated as a Remove method, or a remove method on the home or component interface, the container invokes PreDestroy lifecycle callback interceptor method(s) (if any) for the bean instance after the Remove method completes." JSR-299 is declaring that "destroy" on a contextual object will invoke a removeal path not defined by EJB. ---- 2) JSR-299 defines activity in the middle of EJB Lifecycle JSR-299 PR2 6.11 - "When the EJB container creates a new instance of an EJB, the container must perform the following steps after Java EE injection has been performed and before the @PostConstruct callback occurs..." EJB defines no callback mechanism for a hypothetical @PostInstanciated before @PostConstruct. Thus there's no hook defined for WB to do its magic. ---- I'd like to open up discussion on either adding these points to EJB 3.1 (a bit late in the game) or revising the JSR-299 spec such that it doesn't impose upon EJB. Either way, as I've committed to Pete, I'll be taking on the EJB/WB integration bits. But I do want to ensure the lines are properly drawn. If properly scoped, we should have to alter no code under the EJB3 components to support WB.
