Hi all,

I am new for jbpm. I have passed *boolean value* to the variable name "*qcapproval*". I used *constraints* in bpmn diagram, in that if the variable *qcapproval == true* the process end. otherwise (that is *qcapproval == false*) process continue. But I need to change the variable value as *true dynamically*. Because if i set the variable false loop continues. I need to stop the process in the particular stage. So i need to change the variable value as *true dynamically*. Kindly advise me. I have attached my code below.

*Code:--    * 


            StatefulKnowledgeSession ksession = createKnowledgeSession("Print.bpmn");
            Map<String, Object> params = new HashMap<String, Object>();
            params.put("qcapproval", false);
            TaskService taskService = getTaskService(ksession);
            ProcessInstance processInstance = ksession.startProcess("com.tnq.workflow.jobflow.Print.bpmn", params);
            assertProcessInstanceActive(processInstance.getId(), ksession);

Thanks for looking into this....
