jBPM Persistance

[3biga]

Hi!

I'm working on a jBPM project now and I can't get jBPM to persist its state into the DB. After I run a process, I see no records in the tables. I expect to see some records in processinstancelog, sessioninfo or nodeinstancelog tables, but there's none. I use PostgreSQL.

persistence.xml:

<persistence version="2.0"

  </persistence-unit>

</persistence>

My Java method that invokes jBPM:

public Response test() {
  KieServices kieServices = KieServices.Factory.get();
  KieContainer kContainer = kieServices.getKieClasspathContainer();
  KieBase kBase = kContainer.getKieBase();
  KieSession ksession = kBase.newKieSession();
  ksession.getWorkItemManager().registerWorkItemHandler("Human Task", new WorkItemHandler() {
  @Override
  public void executeWorkItem(WorkItem workItem, WorkItemManager manager) {
  System.out.println("executeWorkItem done");
  }

  @Override
  public void abortWorkItem(WorkItem workItem, WorkItemManager manager) {
  System.out.println("abortWorkItem done");
  }
  });
  Map<String, Object> params = new HashMap<String, Object>();
  params.put("name", "world");
  ProcessInstance proc = ksession.startProcess("test-project.sample", params);
  System.out.println("ID: " + proc.getId());
  return Response.status(200).entity("ok " + proc.getId()).build();
}

After I created the Test schema in DB and run the code, I see that it has created tables, but they all are empty.
