How to view historical process instances in bpm6.0.1?

[suraj.bahl.50]

Hi,

I want to show all process instances which have been completed. Once all tasks in a process is completed then instance object becomes null so cannot see it's status as completed.

Which jBPM API's i can use to view the historical process instances?

If you are using CDI you can inject an instance of RuntimeDataService which will query the JPA database:

  @Inject
    private RuntimeDataService rds;

    public void reportProcessInstances(List<Integer> states, String processId)
   {
        for (ProcessInstanceDesc pid : rds.getProcessInstancesByProcessId(allStates, processId, null))
            ...
    }

on top of what Jay has already provided you can use directly the AuditLogService to get access to history data.

Hi,

I tried to fetch the process instance by injecting RuntimeDataService as mentioned by Jay using following method:

ProcessIntanceDesc processInstanceDesc = rds.getProcessInstanceById(processID);

But I am getting following error:

java.lang.IllegalArgumentException: Named query not found: getProcessInstanceById

Do i need to include add some other jar to include the queries executed by RuntimeDataServiceImpl?

HI Suraj,

That particular query is in jbpm-kie-services.  If you want, you can include all these maven dependencies (below).  You may or may not need them all, so if you prefer you can add them one at a time.

Hi Jay,

I have already included all the jars which are generated in jBPM runtime folder at the time of installation. The jar "jbpm-kie-services-6.0.1.Final.jar" already exist in my lib folder then any clue why it would not be able to find the query...

Thanks,

Suraj,

you need to include Servicesorm.xml mapping file in your persistence.xml so the named queries will be available. See here for an example.

Hi Maciej,

I'll try that...

However, in general i have a question that where can i find all this information? is there any documentation available?

I went through jbpm 6 documentation but didn't find anything mentioning about RunTimeDataService or Servicesorm.xml...

Regards,

Suraj

it's in cdi section of the docs.

I have added Servicesorm.xml in my persistence.xml and now i am getting following error on calling:       

ProcessInstanceDesc processInstanceLog  = runtimeDataService.getProcessInstanceById(processInstance.getId());

Error:

[swiderski.maciej]

that indicates there is no such process instance, with given id. Might be that logging was not enabled and thus it does not store any data.

Process instance was there. How can i enable the logging?

[suraj.bahl.50]

I am able to see the process from auditservice after removing InjectableRegisterableItemsFactory from my RuntimeEnvironment.
