t.b.h. I am very very worried (enough to post).
This is why I use JEE:
I worry that the "Spring" people will "take" over and the simplicity of JEE (that has taken years to perfect) will be lost.
The point of having an EE server, to run on, is that you don't have to build you server from scratch in your own code base (aka Spring).
EE servers are incredibly powerful and millions of man hours has gone into perfecting them.
People are blown away with how productive JEE is (from personal experience).
As another poster pointed out; a lot of java is not about web front ends.
