[jBPM 4]
Is there a simple mean to differentiate the differente possible ends of a
process?
For instance in the example
org.jbpm.examples.end.multiple.EndMultipleTest
that comes with the distribution, a process may have three different ends. But
once the process is ended, how can we know what end it reached?
The Unit Test only tests that the process ended correctly, not that it reached
the intended end ("ok", "bad request" or "internal server error") that are
defined in the JPDL :
| <?xml version="1.0" encoding="UTF-8"?>
|
| <process name="EndMultiple" xmlns="http://jbpm.org/4.0/jpdl";>
|
| <start g="16,96,48,48">
| <transition to="get return code" name=""/>
| </start>
|
| <state g="96,94,111,52" name="get return code">
| <transition g="151,60:-36,11" name="200" to="ok"/>
| <transition g=":-16,-27" name="400" to="bad request"/>
| <transition g="151,183:-33,-32" name="500" to="internal server error"/>
| </state>
|
| <end g="238,37,48,48" name="ok"/>
| <end g="238,98,48,48" name="bad request"/>
| <end g="240,160,48,48" name="internal server error"/>
|
| </process>
|
I did not find how to query about it with the API.
here is what I tried, in EndMultipleTest :
| public void testEndMultipleOk() {
| ProcessInstance processInstance =
executionService.startProcessInstanceByKey("EndMultiple");
| String pid = processInstance.getId();
| processInstance = executionService.signalExecutionById(pid,
"200");
| assertTrue(processInstance.isEnded());
| // end of the official test
|
|
| assertEquals("ended", processInstance.getState());//state is
"ended", not "ok"
|
| //HistoryActivity
| HistoryActivityInstanceQuery historyActivityInstanceQuery =
historyService.createHistoryActivityInstanceQuery();
| historyActivityInstanceQuery.executionId(pid);
| List<HistoryActivityInstance> list =
historyActivityInstanceQuery.list();
| System.out.println("list for pid size : " + list.size());
| for (HistoryActivityInstance historyActivityInstance : list) {
| System.out.println("history activity for pid: " +
historyActivityInstance.getActivityName());
| }
|
| historyActivityInstanceQuery =
historyService.createHistoryActivityInstanceQuery();
| historyActivityInstanceQuery.activityName("get return code");
| list = historyActivityInstanceQuery.list();
| System.out.println("list for \"get return code\" size : " +
list.size());
| for (HistoryActivityInstance historyActivityInstance : list) {
| System.out.println("history activity for \"get return
code\": " + historyActivityInstance.getActivityName());
| }
|
| historyActivityInstanceQuery =
historyService.createHistoryActivityInstanceQuery();
| historyActivityInstanceQuery.activityName("ended");
| list = historyActivityInstanceQuery.list();
| System.out.println("list for \"ended\" size : " + list.size());
| for (HistoryActivityInstance historyActivityInstance : list) {
| System.out.println("history activity for \"ended\": " +
historyActivityInstance.getActivityName());
| }
|
| historyActivityInstanceQuery =
historyService.createHistoryActivityInstanceQuery();
| historyActivityInstanceQuery.activityName("ok");
| list = historyActivityInstanceQuery.list();
| System.out.println("list for \"ok\" size : " + list.size());
| for (HistoryActivityInstance historyActivityInstance : list) {
| System.out.println("history activity for \"ok\": " +
historyActivityInstance.getActivityName());
| }
|
|
| //Job
| JobQuery jobQuery =
managementService.createJobQuery().processInstanceId(pid);
| List<Job> listJobs = jobQuery.list();
| System.out.println("listJobs size : " + listJobs.size());
| for (Job job : listJobs) {
| System.out.println("job : " + job.getId());
| }
|
|
| //HistoryProcessInstance
| HistoryProcessInstanceQuery historyProcessInstanceQuery =
historyService.createHistoryProcessInstanceQuery();
| historyProcessInstanceQuery.state("ok");
| List<HistoryProcessInstance> listHPI =
historyProcessInstanceQuery.list();
| System.out.println("IP list for \"ok\" size : " +
listHPI.size());
|
| historyProcessInstanceQuery =
historyService.createHistoryProcessInstanceQuery();
| historyProcessInstanceQuery.state("get return code");
| listHPI = historyProcessInstanceQuery.list();
| System.out.println("IP list for \"get return code\" size : " +
listHPI.size());
|
| historyProcessInstanceQuery =
historyService.createHistoryProcessInstanceQuery();
| historyProcessInstanceQuery.state("ended");
| listHPI = historyProcessInstanceQuery.list();
| System.out.println("IP list for \"ended\" size : " +
listHPI.size());
| }
|
and here the output :

I tried a bit in all directions, but did not find a clue on how to get more
precision other than the fact that my process is in "ended" state. I have seen
that I could have "cancel" or "error" too (cf
org.jbpm.examples.end.state.EndStateTest), but I would have been interested in
finding some history about the names of the end nodes. For exemple find all
process that ended with "bad request". Is it possible with the API ?
