by default jbpm executor is enabled so there is no need to enable it again. That is based on assumption you run with jBPM conole (aka kie workbench).
Thanks for reply.
But how can i enable it from eclipse project?
What do you mean by enable it from eclipse project? are you using the the kie workbench / jbpm console?
The executor service is like a deamon that runs inside the tooling. If you want to integrate that with your application you will need to inject the services inside your application and start it.
But it returns blank/null value.
What is it so?
how can i see these values?
and can i modify them using System.setProperty()?
If you are using the UI, you can enable the executor from the Jobs Perspective.
