| Re: [jakarta.ee-community] Why not dropping EARs in Jakarta EE? |
I am not trying to split hairs, but I think it’s important that we differentiate between JAX-WS and SOAP. A Jakarta EE developer may have no control over whether the protocol is used since there is a peer involved that they might not govern.On Apr 30, 2018, at 10:28 AM, reza_rahman <reza_rahman@xxxxxxxxx> wrote:______________________________Just to be clear, I am not in favor of deprecating or removing JAX-WS precisely for these reasons.Whether it needs to be part of any other profile by default other than the "complete" or "full" Jakarta EE profile is another question. I think the answer is that it does not.Sent via the Samsung Galaxy S7, an AT&T 4G LTE smartphone-------- Original message --------From: Ben Evans <benjamin.john.evans@xxxxxxxxx> Date: 4/30/18 11:07 AM (GMT-05:00)To: Jakarta EE community discussions <jakarta.ee-community@eclipse.org >Subject: Re: [jakarta.ee-community] Why not dropping EARs in Jakarta EE?Just my own data point, but I train several hundred graduates as new intake at a couple of reasonably savvy banks. SOAP is still very much part of the curriculum.SOAP may not be the new hotness any more, but there’s a lot of it out there & it’s still a major integration tech for 3rd party / vendor products.Thanks,BenOn Mon, 30 Apr 2018 at 15:56, Adam Bien <abien@xxxxxxxxxxxxx> wrote:Just deprecating - not removal.

GlassFish was well on its way to achieving this under Sun ownership until everything with GlassFish went south with the Oracle acquisition.

If these projects are to keep pace with Jakarta EE's more rapid release pace and the resulting testing and acredidation requirements levied by customers then backwards compatibility will be key.

Right now I agree that this is an issue as well we recently moved our EAR deployment from GlassFish to JBossEAP with some headaches.

It is for good reasons that the web profile has been implemented as a subset of the full profile and not as a stand-alone profile, Applications that work with web profile should not break when working with full profile thereby assuring upgrade-ability and portability. If CDI or any other platform technologies has any problems inter-operating with the full profile then it is the responsibility of the respective platform technology stakeholders to address that in their own specs/implementations unless there are valid issues/limitations with any of the full profile specs/implementations. In addition to the EAR support mandated by the JEE full specs, several app servers have provided their own proprietary classloader mechanisms to make packaging and deployment more flexible albeit, at the cost of vendor lock-in/portability.

Also the concept of having a inter-application-wide parent classloader facilitates several implementation approaches such as scoped objects and simplified transaction boundary realization - stuff that are not easy to implement over microservices (and are often ignorantly dismissed as anti-patterns).

My opinion about EARs after years is: It's an awful disaster if you're trying to develop an ear platform independently. So why should it be called 'standard'?
