new project with vaadin7

I’ve tried to make a project with the new version of vaadin eclipse plugin and vaadin7. The instructions in wiki “Creating an eclipse project” for maven: I can’t find the “vaadin-archetype-application”; using Ivy on running the application on JBoss (of course Tomcat inside to JBoss) I have this message on console:
[VaadinServlet]
Requested resource
[/VAADIN/widgetsets/com.example.new_project7.widgetset.New_project7Widgetset/com.example.new_project7.widgetset.New_project7Widgetset.nocache.js] not found from filesystem or through class loader. Add widgetset and/or theme JAR to your classpath or add files to WebContent/VAADIN folder.
It’s impossible to try vaadin7.
For vaadin6 all is ok
