Software is too expensive to build cheaply…

We’ve been getting more interested in using RESTful web services and AJAX based applications recently. One of the tools we’ve been using with that is Jersey – the JAX-RS (JSR-331) reference implementation. I’ve been using it in anger for about a month now, and thought I’d write up some thoughts I had about it.

The idea is simple: create your normal class, and rather than going and fetching things you might want (like datasources, factories, and so on), get them given to you instead. This greatly facilitates things like unit testing, because you’ve got a lot less dependencies to set up.
