No One Is Perfect » github http://watchitlater.com/blog A reluctant foray into the world of blogging.

In my opinion the current crop of web frameworks still make it very easy to do the “bad” thing since to do PRG properly you need to think what kind of an interaction you want with users and not cop out saying its technically very difficult in <insert framework here>. If you resort to ActiveX controls, popups without navigation bars and/or weird javascript hacks to stop users from clicking refresh or back buttons then perhaps you should have written a better web application.

Whenever I play with Rails, or for that matter any other web framework, I get stuck on trying to find a problem to solve (or a set of requirements). Fortunately the Agile Development with Rails book from the Pragmatic Programmers has a nice little bookstore application that I can develop iteratively. I’ve put my latest adaptation of their depot application to use post-redirect-get (even works with ActiveResource scaffolds), UUIDs as ActiveRecord primary keys, HAML, SASS and RSpec on GitHub. Feedback is always welcome.

However I wanted to see what it would take to use PicoContainer as an IoC container within Jersey.

Verdict: not much at all. Nicely extensible.

To see what I mean please take a look at my jersey-pico project on GitHub. I can now create JAX-RS services in Java or Groovy with a very simple IoC container.

This application does not use Spring Framework by deliberate design – as soon as I introduce it to any teaching session I spend more time talking about Spring then talking about what I am usually there to accomplish. As usual, any comments, bugs or enhancement requests are very welcome.
