[rules-dev] Drools Flow in EJBs

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
