I love Roo! Ben Alex and his team have made a great job making starting a Spring project a breeze. However, I’ve shied away from using Java for XHTML/JS/CSS since 2003, so while I know the underlying technologies with Roo (JPA, the databases, Spring, JUnit, Tomcat, etc etc) I don’t know Apache Tiles at all. So I figured I’d like to learn it, at least until Roo 1.1 hits in a few weeks, when I’ll probably want to learn GWT. Stay tuned…

So, for learning this I’m going to make a project I’ve been planning ever since I released my awesome tuner for early music musicians: Well Tempered for the iPhone:  Open Temperament. It’s going to be an open database for tuning temperaments. So, first step, register the domain (let’s hope this isn’t going to be one of those many great ideas that are parked on a domain due to lack of time ), done, and let’s get the basic Roo script up:
