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

Just wanted to pitch in another idea... you can actually use JRuby and Rails (similar to the previous comment about Django and Jython).

If you use JRuby with Rails and JRuby Rack (and maybe some other utilities... I wasn't the one to actually get the integration going initially), you can deploy JRuby Rails additions to an existing Java web app. We have a legacy JSP application deployed with Tomcat, and are now starting to add new pages using Rails with just that setup (in addition to extending the JSP side when necessary). So far it has been quite successful, though we don't have any of the major high traffic pages implemented in Rails, so I don't know how well it will scale.

We have full access to the session, and have even set up mechanisms to invoke JSPs from Rails pages (such as existing header and footer type JSP includes). It takes some effort and trial and error to fully integrate the 2, but if Rails and JRuby is an option, I highly recommend it (as a personal fan of Ruby).

A colleague has dabbled in JBoss Seam, which is a framework by Gavin King (the guy who brought us Hibernate), which was meant to emulate Rails. Having seen both, I feel Rails is a lot easier to develop with.
