Hi, I am trying to get working persistence for workflow and also for audit trail. What really confuses me is why for workflow you use JPA and for auditing Hibernate (chapters 5.1 and 5.3 in the https://hudson.jboss.org/hudson/job/drools/lastSuccessfulBuild/artifact/t... documentation ). I think that it would be better to use the same technology for both. But maybe I am wrong, I am not very experienced in this area. Thanks for your opinions.
