Hi all
I'm trying to signal a newly created ProcessInstance, it sounds workin because I
retrieve the current node and I found that it's the second node in the graph, but,
when I call jbpmContext.close() to close and flush the session I got the following
exception: org.jbpm.persistence.JbpmPersistenceException: couldn't commit hibernate
session
Here is the code
| JbpmConfiguration conf =
JbpmConfiguration.parseResource('/home/mustang/jbpm.cfg.xml");
| JbpmContext environment = conf.createJbpmContext();
| GraphSessin graphSession = environment.getGraphSession();
| ProcessDefinition pd =
graphSession.findLatestProcessDefinition("AProcessDefinition");
| ProcessInstance pi = new ProcessInstance(pd);
| pi.signal();
| environment.close();
|
I'd be grateful if anybody could help me
And here is the full StackTrace:
