I have a doubt regarding persistence. We use "org.jbpm.task" persistence unit for human tasks. We provide Taskorm.xml for orm mapping of sql queries, but where are we including *.hbm.xml file for the persistence entities related to task like "Task", "Escalation" where it could map these objects into their corresponding tables. I can see this for "org.jbpm.persistence.jpa" where we provide "ProcessInstanceInfo.hbm.xml" to persist state of the process. Kindly help me in this. I am using jBPM 5.3.
