I think there is a more fundamental reason. Java, being a compiled language that has traditionally aimed at compile once, run anywhere, offers a significant overhead, but with a development speed of a compiled language. It may or may not be faster to write code in Java vs C++, but it's certainly way faster to write code in Perl, Python, or Ruby. I have always felt that Java was ill-suited to web applications generally, and that the main advantage of using it for web apps was being able to make use of third party libraries written in it. In this regard it's kind of like "why would you write your web app using DCOM on Windows?" Well, maybe because you are recycling VB logic from desktop apps?
