TomEE中的ManagedScheduledExecutorService

Question

My application uses a ManagedScheduledExecutorService provided by the container (TomEE), injected via a @Resource annotation.

Is this my own instance, or is it shared with other webapps running in the same container?

As part of a graceful shutdown of my app, do I want to do anything to this service?

Answer 1

The spec is only dealing with responsibilities and behavior (eg see JSR-236: EE Concurrency Utilities 1.0 - Chapter 3.2)

TomEE is provding a documentation regarding implementation specific configuration of managed resources: TomEE - configuration of managed resources

Is this my own instance, or is it shared with other webapps running in the same container?

Documentation provides this info: "In TomEE resources are mainly 'singleton'..."

As part of a graceful shutdown of my app, do I want to do anything to this service?

The service lifecyle is container managed (see the spec).
