[jboss-user] [JBoss jBPM] - couldn't commit hibernate session

[remon_sherin]

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:
