Before save operation ,I never close context.see this: try { | hsession.save(businessReport); | ProcessDefinition pd = jbpmContext.getGraphSession().findLatestProcessDefinition("RNDFProcess"); | ProcessInstance pi = pd.createProcessInstance(); | //pi.getContextInstance().setVariable("username", from_username); | TaskInstance ti = pi.getTaskMgmtInstance().createStartTaskInstance(); | jbpmContext.close(); | 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(); | jbpmContext.setRollbackOnly(); | }finally{ | jbpmContext.close(); | }
