Hi
I want to add the theme and widgetset into my web application. I want to use spring security role -right base authentication, thats why I am extending the Root class of Vaadin. I have added the Theme at the Root extended class as annotation and I wrote the widgetset pkg into web.xml. But during build it is showing errors -
I am attaching the pom.xml, web.xml and the error log. Please suggest me the correct way.
Thanks 
pom.xml
