hi kukeltje, sorry for bothering u again. i tried to start another hibernate session with a new hibernate.cfg.xml which reads mapping from Student.hbm.xml. but i always got a "Resource: com/dgbdatamodel/Student.hbm.xml not found"exception! i found jBPM puts the deployed files in the tables: jbpm_bytearray & jbpm_byteblock. and the name of the mapping file in the db looks like classes/com/dgbdatamodel/Student.hbm.xml so ... how to locate the mapping file in the code or in hibernate.cfg.xml? (i really got frustrated trying out the possible ways of naming) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4059820#...
