Retrieving Process Variables

[hassang]

Hi

My solution is valid in case you want to get the output at the proper time but not from the process launcher code which is sayHello in your case.

I assumed it is OK for you to read the output from the ExecutionListener which is ExampleExecutionListener in your case.

In case you want to read it from the launcher code then you can try Webcyberrob’s solution below

Obtaining process instance variables as soon as process instance completes

I suspect that if your process uses an asynchronous continuation, your start process call will return when the asyc continuation is reached. In this case, the ended flag should be false. You could consider a user task as implicit async continuation, but you can also declare a task as an explicit async continuation. Ive considered your requirement. If your use case is you want to implement a function as a process; Ensure there are no async continuations. On process completion, store the proce…

thorben’s solution in case you have camunda version 7.6.0-alpha2 or above

Obtaining process instance variables as soon as process instance completes

Starting with 7.6.0-alpha2, there is an API method for this use case, see http://stage.docs.camunda.org/manual/latest/user-guide/process-engine/process-engine-concepts/#variables-in-return Cheers, Thorben
