Setting hbm2ddl.auto does not provide the same behavior as the create.jbpm.schema target of the install ant file. In particular, it does not initialize the JBPM4_PROPERTY table. If you leave hbm2ddl.auto set to create-drop, Hibernate drops the tables when the session factory closes, recreates them when the session factory opens again, but does not initialize the JBPM4_PROPERTY table. When deploying jBPM or any other product on an environment other than what it provides out of the box, be careful to mimic the original environment as closely as possible. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/539898#539898] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
