we have had this discussion already I think. Take a look at this thread:
Hope this answers your question.
P.S.: Does anybody know why the forum search is not working?
I appreciate your answer, but not enough, because i dont know
how can i separate hibernate from jBPM?
I am still quite new to jBPM and I am not an expert on this but I think jBPM depends heavily on Hibernate. Changing jBPM to use a different ORM would require quite some changes and coding.
You would have to rewrite / change all parts where Hibernate is used - this means all method and function calls etc. So there is no easy way or description of changing the ORM used in the project. Whereever persistence is required in jBPM Hibernate is used - so that would mean huge changes.
In case I got something wrote I'll be happy to hear corrections and statements of the advanced users here.
Anyway: What's the problem with Hibernate? Since it is used internally by jBPM you don't have to deal directly with it. So where is the point in changing the ORM?
The forum search obviously is down *again*. It has been down for two weeks, worked for a week now and fails again.
Indeed ... JBoss helpdesk is already contacted multiple times, but they don't seem to get it fixed for one reason or another ... but don't worry - we keep pinging them.
