I have a WebService in which a method is used to create an ExecutorService object for managing some threads. I want to have another method that will allow to shutdown the ExecutorService object. Do I have to create a stateful web service? Or is there another possible solution?
No, as far as I understand, you do not have to create a stateful service. My suggestion is:
- When the operation that is to create the executor service is called, then check if an executor service already exists. If one exists, then exit without doing anything, otherwise create an executor service.
- When the operation that is to shut down the executor service is called, then if an executor service exists, then shut it down, otherwise do nothing.
