How to improve productivity when developing Java EE based web applications

Question

I\'d like to know how you address the seemingly low productivity of Java EE-based web application development compared to other technology stacks (Seaside, Ruby on Rails, etc).<

Answer 1

I would definitely go for Spring together with Hibernate for persistency related stuff.

Why Spring?

The advantage of using Spring instead of another framework is that Springs philosophy is to be "non-invasive". Usually when you're using a framework most probably you'll start to depend on that framework which can be a bad issue if the application is considered to run for a longer time where you then have also to do maintenance etc. Spring uses the so-called "Inversion of Control" (IoC) pattern. Basically your code doesn't (it can but it doesn't have to) call Spring, but Spring will call you (Hollywood principle: "don't call me, I'll call you"). So for instance you can use normal POJOs (Plain Old Java Objects) and you don't have to inherit from any framework-related classes/interfaces. Another big problem (if not the biggest) in Software Engineering are dependencies. You'll fight for reducing them as much as possible since they will make your life harder (especially in maintenance later on). Spring reduces dependencies among your components drammatically by managing the instantiation of components through configuration files and the dependency injection pattern. I wouldn't want to go on, the best thing is that you start reading some tutorials at the official Spring website. Initially it may need some time in the understanding but once you got it you'll earn a lot of benefits.
