Yeah, I don't want to weigh in the JavaScript side of things but I've worked with a ton of "large" Java applications. All of them have been large because... > Everything must be an interface/impl/dao/controller so you get 4 files + hibernate mapping (if not using annotation) + view files. Eventually you have 10 files for every object. > Mid-stream decisions (we need to go from Struts to Spring) that effectively create two separate in-process branches of the code base. > Java developers building their own castle. Some guys "owning" a side of the application and not communicating therefore creating solutions their own way instead of using common libraries. Specifically to your description I would argue whatever you are doing must be in multiple projects or it has been poorly engineered. If it is in multiple projects why couldn't another language take it on?
