Hi people, i got an issue and i hope that you can help me! I'm trying to combine my own persistent classes with the JBPM persistent classes. First I follow the steps described on the following link: http://docs.jboss.org/jbpm/v3/userguide/persistence.html#d0e2412 but i recieve an org.hibernate.MappingException:Unknown entity with my custom class. First I have mi POJO class named: Metric, then I created a Metric.hbm.xml file that try to creates a TABLE NAME="Metric". Finally I put the reference to that file on my hibernate.cfg.xml: Hypersonyc is my defauld DB, and supposedly when I start my jbpm suite my custom table must be created, but it doesn't. I need some help. Thank you! View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4213579#...
