Good Vaadin learning resources


I am new to Vaadin and would like to ask you guys for good learning resources beyond the Vaadin site. This sort of information could probably be found from the internet, but I wanted to ask straight from the professionals.

Thank you

Currently I am reviewing the Vaadin 7 cookbook and it is a ton of good information.


official Vaadin classroom trainings
are a great way to get both basics and advanced knowledge on Vaadin.

Thanks for the replies guys. The classroom training seems a bit too expensive for a student, but I will definitely check out the cookbook.
