Separate business data and process relative data

I tried to understand how activiti works with data.I searched and read several forum posts, so I came prepared to ask question.What I currently understand is following: 1.Activity hides persistence layer and works with Variables, which , if defined as JPA entities, could be automatically fetched fro

I succeed to integrate with Hibernate (Jpa of course), and this my tutorial:
http://serverbabyblog.wordpress.com/2014/03/20/activiti-jpa-integration-using-hibernate/

But I found, that conceptually, when you develop with activiti or with Jbpm , you need realize, what you really want in your design:
1) change business objects as a part of a process transaction
(and then presumably, have these objects tightly coupled with the way activiti operates, e.g. you obliged choose JPA or MyBatis as a way you connect the app to the database )

2) change your business objects in separate transaction, may be in separate connection, may be in separate data base…
And then you have a freedom of ORM approach , but you need your own ways to rollback the change, if this rollback required by the virtue of the business process.

For me it looks a sort of a hard choice..

I have a similar problem, see http://forums.activiti.org/content/example-spring-configuration-transactionmanager-required

I'm sure that operations on business data and Activiti data could run in the same transaction, perhaps with JTA. I hope there will be a solution soon.

beep02: correct that is the tradeoff. I always found it a best practice to have it a separate from Activiti. Activiti should't be the master of your data. but indeed, it comes with the price of custom rollback, unless you can hook it up with some JTA enabled datasource.
