JPA in Vaadin with application managed entity manager

Vaadin 6 / 7 / 8 Framework Data Binding

Hey,

is it possible to use JPA in Vaadin with an application managed entity manager? We use only Tomcat but no J2EE-server so we have no container managing the JPA entity manager lifecycle. Furthermore we cannot use the JPA Container Addon because our JPA implementation does not fully support it (openjpa 2.2 with hector-jpa for Cassandra).

It’s possible. To learn how to do that check the JPAContainer add-on or just use this vaadin plugin.
