That's interesting. To me, J2EE is a pic failure in turns of developer enthusiasm (might be considered successful because of usage). I am yet to meet a developer who likes to code in J2EE and they would take every opportunity to jump ship to just about anything. That said, mine is a startup world and nobody I know writes new code in J2EE.
I have nothing against Erlang. Good for erlang if its successful. I wonder why then I see AOL these defensive posts about why Erlang has not been adopted enough
