cann't run sampler.war in gatein


Using gatein 3.1 on jboss 5
download sampler.war, put it in deploy server folder.
When accessing sampler portlet get following message in server console and javascript:

Requested resource [VAADIN/widgetsets/com.vaadin.portal.gwt.PortalDefaultWidgetSet/com.vaadin.portal.gwt.PortalDefaultWidgetSet.nocache.js]
