...and, as we discovered at the Open Source User Group meeting on 24th March, also on the iPod Touch!
If you'd like to explore in detail the application I used yesterday, download it from GitHub. The webapp uses, as the headline suggests, Spring MVC (with particular focus on
ViewResolvers), and alongside the bog-standard JSP code, exploits jQTouch to make the iPhone/iPod Touch interface look very native app-like.
Alternatively, if you don't want to get messy with the source code, you can just download the Spring MVC iPhone Slides.
