i m a newbie and followed the book for vaadin to try to create my first app for GAE.

I followed the stuff and put Google app engine for the servlet configuration. Rest as the book said.

When i ran the default app created by vaadin on tomcat it throws following exeptions:

I am guessing from the stack trace that you do not have Google App Engine libraries in your project.

tx… rightly said…

So here is the real question:

What all is need to finally deploy it to GAE?

i mean if u use the g+ sign in eclispse u get a pre-configured app ready to be deployed to GAE by just pressing the blue icon.

In the vaadin project what all i need to do?

In short you get it working by:

  1. Create a new Vaadin project
  2. Enable Google App Engine in project properties
  3. Deploy
