Hi there,

I have seen in chapter 6 of the documentation, that Drools Flow can be configured to use JPA and transactions to persist the running states. However, I am in a EJB where I obtain entity managers with a @PersistenceContext annotation, and the transactions are managed by the container, whereas in the example an EntityManagerFactory and a TransactionManager are used.

Could I configure Flow in a direct way to be used by my EJB?

Thanks very much,

Ok, looking at the code, I guess that Drools flow is not ready to work with standards EJBs. The reasons are the following:

* The JPA annotations are not standard JPA annotations, but hibernate ones. For example "CollectionOfElements" in ProcessInstanceInfo class.
* Transactions are managed by Drools, as opposed to some EJBs where transactions are managed by the container.

As for that, I will probably modify the codes, so Flow could be used in our EJBs. I would like to know if someone could guide me on what should I modify.

I will post the modifications in case they are of interest to someone.

Thanks very much,

tizo
