Hi,
I got the same errors mentioned by you in your first message. Mauricio's reply was helpful in knowing about the cause.
But unfortunately I was unable to rectify the error as I am new to Hibernate concept. Luckily there was help from bpmn2user
in one of his blog articles which explains in detail for introducing persistence. Please find the link below.

Hello Process ( with persistence )

I did try the one with persistence. But there were error messages related to Bitronix Transaction Manager. I don't have the
error messages with me rigt now. I will post it tomorrow with more details.
You may also want to check bpmn2user's blog which has several interesting and informative articles explained very well.
