New with vaadin


I’m new with Vaadin, I already tried all the Vaadin project samples, now I’m wondering if someone has a full project Vaadin with MVC, using JPA and EJB. I’m a student and want to know how to use Vaadin properly.

Hi, here’s one (smallish) example I have of using Vaadin with EJB/JPA:

I have some older ones as well, but they’re similar. People have tried this in various ways, but to me the simplest way to get an EJB reference in your code is to have it injected into the servlet that loads the Vaadin app. My example is with Vaadin 6, but the same idea should work with Vaadin 7 as far as I know (am just now learning about v7).
