Hatim has written a very nice blogpost about Roo and Spring Security, including source and going into a good level of detail.

I don’t know if you’ve noticed yet, but I’m a big fan of both Roo and the guys behind Roo. Big thanks to Alan & James from the forum post, ROO-1537 and ROO-1538, as of git version a474dc7b95613fae564f0e0fa50d89a6818bd753, and tested today one day later, my scripts run flawlessly through the tests! Which means, we can continue with Tiles. Stay tuned!

While resolving the test problems in the last code, let’s look at what we get by doing a

mvn jetty:run

The application has a header on top, a footer in the bottom, and a menu on the left hand side. This is in line with the Composite View pattern described in the Tiles tutorial:. To recompose this layout, see src/main/webapp/WEB-INF/layouts/layouts.jspx. In there you find that what we want to work with is , but working with this file will let you get the basic layout you want. The different attributes are found in layouts.xml, and they reference their respective files in /WEB-INF/views, so that should get you started making a nice template

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:
