Between Rod's recent blog on the origins of the Interface name, a recent thread querying the renaming of Acegi Security, and a suggestion late last year from my colleague Ben Hale to blog about the origins of the "Acegi" name, I've decided that it's probably time to do so! First of all, the pronunciation: it's Read more…

Spring 2.0.1 introduced an AbstractRoutingDataSource. I believe that it deserves attention, since (based on frequent questions from clients) I have a hunch that there are quite a few 'home-grown' solutions to this problem floating around.

I was on site with some clients the other day, and they asked me about unit testing and mock objects. I decided to write up some of the discussion we had as a tutorial on creating dependencies (collaborators) for unit testing. We discuss two options, stubbing and mock objects and give some simple examples that Read more…
