New to Vaadin

Hi all,

I come from a java education with some front-end development experience using SmartGWT framework. I have also have been exposed to an ORM named iBatis. I’ve been asked to reseach Vaadin and develop a prototype that would basically consist of a widget bound to a relational database. I am pretty new to all of this and want to know if there are any good example applications that could help me implement this solution. Thanks!
