Upgrade hibernate to the latest, not the old one you have running on ur hdd. for me it was hibernate3.2(latest). next problem will be no transaction defined or something similar. change the example code to | jbpmConfiguration = JbpmConfiguration | .parseXmlString("<jbpm-configuration>" | + | | // A jbpm-context mechanism separates the jbpm core | // engine from the services that jbpm uses from | // the environment. | | " <jbpm-context>" | + " <service name='persistence' " | + " factory='org.jbpm.persistence.db.DbPersistenceServiceFactory' />" | + " <service name='tx' factory='org.jbpm.tx.TxServiceFactory' />" | + " </jbpm-context>" | + | | // Also all the resource files that are used by jbpm are | // referenced from the jbpm.cfg.xml | | " <string name='resource.hibernate.cfg.xml' " | + " value='hibernate.cfg.xml' />" | + " <string name='resource.business.calendar' " | + " value='org/jbpm/calendar/jbpm.business.calendar.properties' />" | + " <string name='resource.default.modules' " | + " value='org/jbpm/graph/def/jbpm.default.modules.properties' />" | + " <string name='resource.converter' " | + " value='org/jbpm/db/hibernate/jbpm.converter.properties' />" | + " <string name='resource.action.types' " | + " value='org/jbpm/graph/action/action.types.xml' />" | + " <string name='resource.node.types' " | + " value='org/jbpm/graph/node/node.types.xml' />" | + " <string name='resource.varmapping' " | + " value='org/jbpm/context/exe/jbpm.varmapping.xml' />" | + "</jbpm-configuration>"); | | well, this fixed it View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4073209#...
