    how to find all processInstance

    ciccio ciccio Newbie

      Hi guys,

      i start new processInstance everytime i catch an event in my java thread. I'm not in jbpm-console.

      I'd like to see the state and catch the end of them.

      Any suggestions?

      Thanks in advance

          I'm trying by myself to make query to db with

          JbpmConfiguration instance = JbpmConfiguration.getInstance();
                    JbpmContext context = instance.getCurrentJbpmContext();
                    try {
                         Session hibernateSession = context.getSession();
                         Query query = hibernateSession
                                   .createSQLQuery("select id_ from...
          

           

          with jbpm-3.1.4.jar. But i have an exception:

          So... Any idea? Is there a simple way to find all processInstance given processInstanceId or Key?

          Can anyone help me?

          TIA

            Use the Query API to get the list of Process Instances for a given ProcessInstanceID.

             

            I used below code to get the process instances.

            getExecutionService

              ProcessEnginer.get(ExecutionService.class)..createProcessInstanceQuery().processInstanceId(ProcessInstanceID).list()

                He is using jBPM 3 I think....

                  No, im using jbpm 4.3.

                  I'm explain my case:

                  I have a DirectoryListener and on addFile

                   dm.addDirectoryChangeListener(new DirectoryChangeListener() {
                              public void directoryChange(DirectoryChangeEvent dce) {
                                  File file = (File)dce.getSource();
                                  if (dce.getType() == DirectoryChangeEvent.FILE_ADDED) {
                                       HashMap<String,String> hashMap = new HashMap<String,String>();
                                       hashMap.put("image_path", file.toString());
                                 executionService.startProcessInstanceByKey("DEMO",hashMap);
                                 System.out.println("added: " + file.toString());
                                  } else if (dce.getType() == DirectoryChangeEvent.FILE_REMOVED) {
                                      System.out.println("removed: " + file.toString());
                                  }
                              }
                          });
                  

                   

                  When a file is added on dir, a new processInstace is started.

                   

                  Using

                  List<ProcessInstance> listP = processEngine.get(ExecutionService.class).createProcessInstanceQuery().processInstanceKey("DEMO").list();
                  

                  and while there are a lot of processInstances, the listP is empty.

                  I think that i can't use .processInstanceId("") because every process has a own Id (eg DEMO.xxxxxxx)

                  Any Idea?

                  TIA

                    HI,

                     

                    it seems like key is not set in JBPM4_EXECUTION table that's why the list is empty.

                     

                    You could do one of two things:

                    1. use process definition id to return all process instances of given definition

                    2. assign process definition key and process instance key while starting, this could be a solution if you can use this pair when querying for process instance and then you could use processInstanceId, check out user guide http://docs.jboss.com/jbpm/v4/userguide/html_single/#withakey

                    For instance, you could use something like this: DEMO.{file_name}

                     

                    Cheers,
