How to retrieve in java the value of the data process ?
Answer edited:
First, a simple recommendation: instead of using the getRootProcessInstanceId() method, you should use the getSourceObjectId() method. In fact, getArchivedProcessDataInstance expected to receive the process instance id as it was when the instance was "live" (i.e. not yet archived). Using getRootProcessInstanceId() should not be an issue as searchArchivedProcessInstances() will not return any sub-processes (and so root process instance should be the same as source object id).
I didn't did any important modification and it seems "to work just fine for me".
You can find below my version of the code and the associated Maven pom.xml file to build the project. Maybe you can try to run it and share with me log output (or your existing log output / stack trace).

Currently, there is no sub process but if I call getId instead of getRoot..() it didn't work !
Well, here are the logs : (don't think it is very useful)
11:02:46.791 [main] INFO - Found 129 archived process instances for process XXX 11:02:46.795 [main] INFO - Root process instance: 41008 11:02:46.795 [main] INFO - Source object id: 41008 11:02:46.795 [main] INFO - Process name: XXX 11:02:46.811 [main] INFO - value: yyyyy 11:02:46.811 [main] INFO - Root process instance: 42002 11:02:46.811 [main] INFO - Source object id: 42002 11:02:46.811 [main] INFO - Process name: XXX 11:02:46.822 [main] INFO - value: eeeee .....

I had to ask in order maybe to find the solution :
Using this from ProcessRuntimeAPI
DataInstance getProcessDataInstance(String dataName, long processInstanceId) throws DataNotFoundException Get the value of named data item from a specified process instance. The value is returned in a DataInstance object.
http://documentation.bonitasoft.com/javadoc/api/6.3/org/bonitasoft/engin...(java.lang.String, long)
When calling the getProcessDataInstance, are you sure that you set the "dataName" with exactly the same name as process data defined in the Studio?
Also can you share your code that you write in order to get the "processInstanceId" that you use?
Thanks.
I answer instead of Romain :)
Here is what we use :
LoginAPI loginAPI = TenantAPIAccessor.getLoginAPI(); APISession apiSession = loginAPI.login(bonitaLogin, bonitaPassword); ProcessAPI processAPI = TenantAPIAccessor.getProcessAPI(apiSession);
SearchOptions searchOptions = new SearchOptionsBuilder(0, 250).filter(ArchivedProcessInstancesSearchDescriptor.NAME,"process_name").done(); SearchResult archivedProcessInstanceResults = processAPI.searchArchivedProcessInstances(searchOptions);
List archives = archivedProcessInstanceResults.getResult();
for (int i=0;i<archives.size();i++) { ArchivedProcessInstance api = (ArchivedProcessInstance) archives.get(i); ArchivedDataInstance di = processAPI.getArchivedProcessDataInstance("data_name",api.getRootProcessInstanceId());
String value_to_retrieve = di.getValue().toString(); }
