How to refresh vaadin JPAContainer once again any updation in db

I am fresh to vaadin, i dont have any idea about how to refresh Jpacontainer when data row updated in mysql db.
Note:Hibernate provider

Your best bet is to use a Hibernate Interceptor to detect when objects of that specific class have been modified, and use that event as a starting point. I would also add something like BlackBoard to decouple your views (or data model handler) from the Interceptor. You can additionally use BlackBoard to notify multiple Applications if you need to.
