hi everyone,
I am a beginner, I want to get correl id by workflow api,
my code is as follows,
ControlObject controller = wfLogon(wfProps, wfPropertyNamePrefix);
ExecutionService es = controller.getExecutionService();
// Query a set of processinstances (30 at maximum), sort them by name
ProcessInstance[] procInstances =
es.queryProcessInstances("NAME='F2_TelnActivating-200602272982427'", "NAME DESC", max_process_instance );
i want to get correl id from procInstance[0], but it seems not function supported.
Can somebody help? thanks very much! |

Correlation IDs are only used when using the XML interface. When using the API you never need a correlation id. Have a look at some of the IBM supplied samples.

| After completely agreeing with John, I wanted to see why somebody needs a CorrelId and in what context. |

There is a repository on this site (on the top of the page).
Goto the java section and there is a ProcessTemplateCreateAndStartInstance program that does exactly this. |

Hi guys,
Its been a long time since I worked on Workflow, but is there a correlId in workflow, isn't it only in MQ messages.....?
Are you guys referring to the same correlId...??
If yes, then how can workflow have the API of MQ....won't we explicitly have to set it in a variable or the processInstanceId or whatever.....
Regards. |

I know exactly what u mean, normally it is. but if this MQ message lost( for some reason),
and we need to write a tool to resolve this issue, and the only thing we know is process instance name, so I want to get correl id by process instance name, then I can construct a reply message containing this correl id and send it to exexmlinputq.
And now I get the correl id by directly connect to db2,  , though sucessful,I think it is a bad way.
and i want to get it by using workflow api directly.
Thanks |

This is not possible

I want to know how.
Because, MQ will not lose it. If you make the same efforts to rewriting your program, include some transactional behaviour, message will not be lost |

Hi neweric,
You could browse the message, create the instance and then do a read on it, if the instance creation was successful.....
Also, you could store the corelId in the instance name, or the description or as a variable in the workItem.....
Regards. |
