Oh, no I have no problem with enterprise Java - it was merely an observation. Enterprise Java exists because it works, after all. I just find it interesting that most software projects will eventually come to the same conclusions regardless of their original source.
Actual hexagonal design is useful software architecture. It may just be extremely poor presentation, but I am far from convinced that the dictates in the article, or the very little bit of very abstract sample code it provides, reflect useful architecture (Hexagonal or otherwise) -- certainly, its not a presentation that fosters understanding and intelligent application over cargo-culting.
