well, there are differences between engine exceptions and businessservice exceptions. The latter in our case were stored in specific processvariables called error__<seq#> they were used to direct the process (e.g. decisionnodes) to nodes where appropriate action could betaken. So that is kind of what I think Jim means by making it part of the process. It would be nice to get this in a full example though but I'm still waiting for the jBPM book to arrive, might be something in there.
