Could you please give a simple example of config required to run the dvd store example in a way that jBPM uses a separate database (ie NOT the orders database)? I have tried several combinations of multiple persistence-units + @PersistenceUnit and also leveraging the components.xml file (as per chapter 4 of the doc). Exceptions seem to be suggesting that the annotations are being ignored (ie empty unitName on EntityManager's persistence unit). PS I think this is a big step in the right direction. I have only just started playing with Seam. The examples are pretty impressive and I have a couple running in Eclipse. The documentation is getting there too.
