Re: [] Why not dropping EARs in Jakarta EE?


EARs are a nice idea. But they are basically non portable between containers ever since.
Especially when it comes to accessing or sharing information between WARs.
This severly affects CDI for example.

This is due to the lush definition of the visibility rules in the umbrella spec.
The EE spec only talks about SHOULD, and doesn't even define a default visibility strategy which MUST be supported

I've had a long discussion with Linda, Bill and a few other EE leaders about this already (starting early 2015).
During that I've created a sample which highlights the visibility issues back then:
