Your 5 minute tutorial is not beeing displayed.

Hello guys,

The deployment is successfull.

And I see “Address Book” in the title. It means that there is response.

But nothing is displayed except the background color;

and got this fucking error;

any ideas?

If you have mapped the application to a context other than root in your web.xml, you also need to map /VAADIN/* to the same servlet (or serve them statically under the root).

the book
for details.

Thank you, Henri!
