[jboss-user] [JBoss jBPM] - Making JBPM and Hibernate Work Together
hi ,
i am trying to make JBPM use Hibernate session .
the JBPM code worked with before .
the error i get is :
| 16:15:07,937 ERROR [STDERR] org.hibernate.MappingException: Named query not known:
GraphSession.findLatestProcessDefinitionQuery
|

org.hibernate.impl.AbstractSessionImpl.getNamedQuery(AbstractSessionImpl.java:70)

|
| at com.mts.WF.Engine.RequestsHandler.handleRequest(RequestsHandler.java:88)
|
| at com.mts.WF.Engine.WorkerThread.run(WorkerThread.java:30)
|
|
the code :
| JbpmConfiguration conf = JbpmConfiguration.getInstance();
| context = conf.createJbpmContext();
|
//context.setSession(HibernateSessionFactory.getSessionFactory().getCurrentSession());
|
|
| String fileName =
FileHandler.assembleName(req.processProperties.Path+req.processProperties.Name,
"processdefinition.xml");
| FileInputStream fis;
| fis = new FileInputStream(fileName);
|
| ProcessDefinition pd = ProcessDefinition.parseXmlInputStream(fis);
| if (pd == null) {
| logger.error("Unable to read definition: " + fileName);
| //context.close();
| return;
| }
|
| context.deployProcessDefinition(pd);
|
the error happens on the last line .
i have tried to make JBPM work with the already opened Hibernate session
by :
context = conf.createJbpmContext();
context.setSession(HibernateSessionFactory.getSessionFactory().getCurrentSession());
but is has crash because no CurrentSession is configured in the
hibernate.cfg.xml
i have tried entering this property with thread, JTA , MANAGED
values - with no success .
how can i resolve it ?
Thanks,
Yair
