couldn't commit hibernate session
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:
