My Java EE Container Choice

It has been a while since I've worked with Java EE.  Back then, we were still using JBoss 3.2.7.  Bootstrapping, we didn't have much resources and relied on open-source, free-to-use, software.

Reviewing the current technology, how much things have changed.

I have read a few articles and it seems the right Java EE container choice is TomEE.
