Yes. J2EE is the de-facto standard for in-house development and there is some reasons behind. They think their code is a safe investment. Why? Because they are still believed in that slogan - "code once run everywhere" which was actively used by IBM and Sun to sell their hi-end hardware. Second they think their code is cheap to maintain and extend because there are a vast crowd of J2EE developers, especially in developing countries. And, yes, off-shoring. It is so good to "save" budgets. Together that is why. Java is backed by so many big companies because it is the cheapest way of off-shore development (coding fabs). And of course, project managers and IT executives in an investment banks does not want to create another facebook. They want their paychecks and bonuses and paybacks from their offshore partners.
