You can use the Variable Persistency Strategies, that will store your facts in the database for you. 
You need to configure in the environment the strategies for example:
https://github.com/droolsjbpm/jbpm/blob/master/jbpm-human-task/jbpm-human-task-core/src/test/java/org/jbpm/task/service/persistence/variable/VariablePersistenceStrategiesSyncHTTest.java

Notice that you will need to provide your domain specific entityManager to the JPAPlaceholderResolverStrategy

Hi,

   We are in a fireUntilHalt during a persistent StatefulKnowledgeSession using JTA & JPA with Hibernate ... Our session consists in a series of facts ( well, we are not different of anyone else for that matter ... xD ) but some of our facts are also JPA @Entity . What we want is to persist those entities on their own database tables as well as the SessionInfo each time Drools considers the knowledge session needs to be persisted.

   We are aware that Drools uses org.drools.persistence.jpa.persist(SessionInfo) .... What would be the best approach to get certain facts that are JPA Entities persisted along with the Session taking advantage of the Drool's SessionInfo persistence loop?

Best regards,
