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
