Vaadin Element in Liferay (Osgi)

Is there any example or support for Vaadin Elements winside Liferay DXP (i.e., OSGi environment).

I tryed to follow the example (for a Grid element) as it was in a servlet environment. The problem is that inside OSGi Liferay DXP it doen not find and parse correctly the html files.

Does somebody has used vaadin element inside LiferayDXP?
