You're right, and I plan on ignoring this one in the future. From looking at the list, I can tell you I've seen every one of those points discussed over and over in different places, whether it be here, rails-core, ruby-talk, or on blogs. Which point haven't you seen discussed before? If a technical lead was actually doing their due diligence, they would have already found the past discussions from both sides on all those points, evaluated it, and made a decision. Instead we have yet another yet another j2ee vs rails "question" looking for "easy answers" when there are none.
