how to find all processInstance

[cicciovega]

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

[mike_burton]

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,
