Hi there,<br>
<br>
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.
<br>
<br>
Could I configure Flow in a direct way to be used by my
EJB?<br>
<br>
Thanks very much,<br>

Ok, looking at the code, I guess that Drools flow is not ready
to work with standards EJBs. The reasons are the following:<br>
<br>
* The JPA annotations are not standard JPA annotations, but
hibernate ones. For example "CollectionOfElements" in
ProcessInstanceInfo class.<br>
</div>
</blockquote></div>
That was the one element we couldn't find a replacement for in JPA1,
JPA2 fixes this, but we haven't updated to JPA2 yet. I don't believe
we use any other hibernate specific annotations.<div class="im"><br>

You can use both JTA transactions and local entity transactions. So
transactions can be drools maintained or container/external
maintained.<br>

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. <br>
<br>
I will post the modifications in case they are of interest to
someone.<br>
<br>
Thanks very much,<br>

Could you tell me how can I use Drools with my container managed transactions, or where can I read how to do that?. I think that the example given in the documentation (Drools Flow, 6.1.4 - Transactions) does not apply to this case, and I can't figure out how to do it.<br>
<br>Thanks again,<br><br>tizo<br><br></div></div><br>
