first,i want say sorry ,because i'm a Chinese and english isn't well.
i think you can know the folowing language:
when i do this:
RndfReport businessReport = new RndfReport();
| businessReport.setExampleName(example_name);
| businessReport.setExampleRemark(example_remark);
|
| JbpmConfiguration jbpmConfiguration = JbpmConfiguration.getInstance();
| JbpmContext jbpmContext = jbpmConfiguration.createJbpmContext();
| Session hsession = jbpmContext.getSessionFactory().openSession();
| Transaction transaction = hsession.beginTransaction();
| try {
|
| hsession.save(businessReport);
| transaction.commit();
| ProcessDefinition pd =
jbpmContext.getGraphSession().findLatestProcessDefinition("RNDFProcess");
| ProcessInstance pi = pd.createProcessInstance();
| pi.getContextInstance().setVariable("username", from_username);
| TaskInstance ti = pi.getTaskMgmtInstance().createStartTaskInstance();
| ti.setVariable("report_id", businessReport.getReportId());
| ti.end();
| } catch (Exception e) {
| System.out.println("Unknown error in the SaveGo().");
| return_code = Property.SQL_ERROR;
| message = "?????????";
| event_type = "";
| e.getMessage();
| e.printStackTrace();
| transaction.rollback();
| }finally{
| hsession.close();
| jbpmContext.close();
| }
