How to define process variables inside a process

[kaech]

Hi,

what is the easiest way to define process variables inside of the process?
I don't want to inject them from the outside but define them as part of the process.

Maybe using a little Groovy script or a Java service task?
Ideally directly in BPMN. But I can't figure out how it can be done.

What would be the easiest way? Your suggestions would be highly appreciated.

I think I found it. Using a script task would be the simplest approach.
I's described in the user guide http://www.activiti.org/userguide/index.html#bpmnScriptTask.

I think u can do it with or during Java Service Task also:


public class ServiceTask implements JavaDelegate {
           public void execute(DelegateExecution execution) throws Exception {
                  execution.setVariable(variableName, value);
           }
}


Good luck
