I am sorry for my concepts as i am newbie to this Workflow development and if it does not make sense to you. poor me, Any ways i'll try again. According to jBPM-jpdl documentation "jBPM only stores Strings as actorIds and doesn't know the relation between the users, groups and other identity information." What if i want to manage these relationships for our application? Another question: How do we integrate the jBPM processes in our Web application? Will it be Web services or a simple jar or we have to customize the process that we deployed on the server??
