I don't understand what you really mean by your question. Anyway, for large projects, netbeans is a great choice. It supports enterprise applications, refactoring, cvs, all kinds of servers and more.
NetBeans is the best, and most user friendly IDE around. From mobile to enterprise.
I wouldn't totally agree on that. Eclipse and IntelliJ have a lot of great features too. Eclipse with MyEclipse might be a lot better than netbeans. It all depends on your perspective, and what you are looking for in an IDE.
