Re: [jakarta.ee-community] [jakartaee-platform-dev] Sanity Check - Makin

All of this is properly solved once “Micro Profile” moves to the platform where it rightfully belongs. No weird band aids necessary to try to solve a compound fracture.

Subject: RE: [jakartaee-platform-dev] Sanity Check - Making Core Profile a Dependency of Web Profile

 

Hi,

Reza, thank you for the link.

It is easy to forget to keep these guidelines front and center.

I think the whole integration of all these things whether it is Core Profile, Web Profile, MicroProfile, CDI Lite, Servlet, Jakarta REST, JCA, or JCA or the entire Platform, it is a lot trickier than people realize. Why did we have Managed Beans and CDI, why do we have similar annotations here and there, why can't you just use MicroProfile in a Web Profile runtime without gotchas or any of the MicroProfile specifications separately? Well, integration is hard. And I know as I am still on what has proven to be an extremely long road with the Piranha project to certify against the Core Profile let alone the Web Profile or even the full platform.

It is from that perspective I would implore folks to take a step back and look at the larger picture here. In the end a developer does not care about this profile, that platform, that specification or whatever.

What they care about is being able to use it without hassle and gotchas and if anything puts that at risk we should think twice about it.

In closing I want to call out that historically we shipped separate API jars and documentation for the platform and Web Profile and there was no Maven dependency between the two. So, from that perspective I fail to see why Core Profile should be any different.

This brief follow-up is not aimed at anyone in particular but rather a general attempt to try to potentially better inform anyone interested in this discussion. It is helpful to carefully read the Profiles section in the Jakarta EE specification:
https://jakarta.ee/specifications/platform/11/jakarta-platform-spec-11.0-m5#a3212.
The reason I am familiar with this content is because I helped formulate this as part of the Java EE 6 expert group so many years ago. I understand this all seems pedantic to some, but this is the nature of open specifications as opposed to just open source. The accuracy, reliability, and integrity of what is in these documents matters.
