You’d often have to worry about environment variables such as the classpath, and installing the tools into your environment. Installing major Java frameworks is a major time drain.

3: Features that boost the productivity of Ruby over Java 43 P RODUCTIVITY For long-term productivity, you also want a language that allows rapid extension. Dynamic languages have an excellent reputation for reducing coupling and for allowing extensions in ways that Java can’t. In Beyond Java, I make the case that many cumbersome and complex extensions in the language (using buzzwords such as dependency injection, aspect-oriented programming, and XML-based configuration) are needed precisely because Java is difficult to extend in certain ways.
