Use Vaadin with google app engine

Question

I'm just wondering if its possible to have a Vaadin project working under google app engine? If it is then please refer me to any kind of documentation or "how-to".

Answer 1

The Vaadin wiki contains a step-by-step process.

Answer 2

There is an ticket about supporting Vaadin by GAE: http://dev.vaadin.com/ticket/2835

I've tried it - and id works. First of all you need to enable sessions:

<sessions-enabled>true</sessions-enabled>

and use GAEApplicationServlet instead of default vaadin's.

Second: make sure that all you domain objects, are serializable (i bet it's no problem, btw)

And third: move all static files (theme css and images) from vaadin's jar to your webapp folder
