I'm afraid to say this, but you sound exactly like someone with very little experience when it comes to large scale enterprise systems (your "serverlets" sums it up).

Java EE is extremely powerful if you can wield its power, and obviously a good understanding of object oriented programming and design patterns is critical in order to make systems that are rock stable, safe (container managed transactions comes to mind) and scalability.

I think you'll see my point once you start working on larger problems. It's not random that many really big enterprise projects (such as banking software) are based around Java EE, and not Ruby on Rails.

Note that I am not trying to be overly negative - it's just that I see this kind of argument all the time, usually from people with no real enterprise experience.
