Are you using other than core Vaadin components? If so, remember to compile widgetset.

In web.xml’s servlet definition you should have widgetset parameter with value that points to com.your.application.ApplicationWidgetset widgetset in WebContent\VAADIN\ folder


Also, if you’re using other than /* servlet-mapping, you should add


mapping to your web.xml.

You can easily compile the widgetset with for example Vaadin Eclipse plugin

Thanks i got it -_-
