Hi guys, I have a problem persisting a process instance using hibernate. Here is the scenario: - I had a project based on jBPM, created on seam 4.0; when persisting a process instance there were no problems - in the meantime I changed the project structure to work on seam 4.2; and now I get error when persisting the process instance; below is the error: 12:35:10,017 ERROR [STDERR] org.hibernate.MappingException: An AnnotationConfiguration instance is required to use <mapping class="ro.fii.projectmanager.model.Flow"/> | at org.hibernate.cfg.Configuration.parseMappingElement(Configuration.java:1600) | ... and here is the code that is used to persist the process instance: JbpmConfiguration jbpmConfig = null; | JbpmContext jbpmContext = null; | try { | jbpmConfig = JbpmConfiguration.getInstance(); | jbpmContext = jbpmConfig.createJbpmContext(); | ProcessDefinition pd = ProcessDefinition.parseXmlString( | "<process-definition name=\"pd-name\">" + | " <start-state>" + | " <transition to='s' />" + | " </start-state>" + | " <state name='s'>" + | " <transition to='end' />" + | " </state>" + | " <end-state name='end' />" + | "</process-definition>"); | ProcessInstance processInstance = new ProcessInstance(pd); | jbpmContext.save(processInstance); | } | catch(Exception e) { | e.printStackTrace(); | } | finally { | if (jbpmContext!=null) { | jbpmContext.close(); | } | } Even stranger is that when I comment my classes from hibernate.cfg.xml and then try to persist again the process definition I don't get any errors, but the first time it wants to persist the process instance, all the classes from hibernate.cfg.xml are re-mapped and then the process instance is saved. I don't know exactly what to ask from you. If anyone has any suggestion they are more than welcomed. Thanks!
