Re: [jakartaee-platform-dev] Should we consider rebasing Enterprise Beans Lite to a mapping/extension on top of CDI?

Doesnt RPC means nothing? Some will say GraphQL (others will hate it), some will say gRPC (same), others will say JSON-RPC, others will just bring back SOAP to life.
RPC is likely a synonym to "single endpoint for multiple handlers" but without a format (JSON in EE for ex to stay consistent) and a transport it is undefined and hard to integrate (as were remote EJB between services when not the same vendor and version).
So on EE side the one making the most sense is likely JSON-RPC since it will enable to be interoperable and optimized but guess it can start a lot of debates we should maybe avoid to work on a stronger and lighter platform instead?

Yes, Payara has EJB over HTTP and gRPC currently, but that’s proprietary. 
I think there should be some kind of RPC plan post-EJB on the spec level.

Just out of curiosity, is EJB-deprecation-in-favor-of-CDI going to contain RPC of some kind?

EJB Lite would not, as Remote Beans are only in EJB Full. EJB Full is way too complex I think to ever rebase on CDI without making it a totally different spec.
Listening to the industry “weak signals” it sounds like RPC is coming back into fashion.
Would hate to miss that hype, especially that remote EJB-type RPC already exists and well-understood and tested…
Bring back remote EJBs? in CDI form?

I did something in Payara that approximated this. There were plans to take that even further, but you know how these things go.
