Vaadin with JPA EclipseLink

Hello I am new to vaadin and don’t know how to combine vaadin with JPA Eclipselink.
I have designed a form in which tere are some controls like TextField button etc.
When the user click on button the value of the textfield should be stored in the database.
I have designed the form but having problem in incorporating the database operation with JPA eclipselink.

Vaadin JPAContainer
