Managed scheduled executor service: The ManagedScheduledEx-
ecutorService interface extends the ManagedExecutorService and
java.util.concurrent.ScheduledExecutorService interfaces in
order to execute a task at a specific time.
• Instances of this interface are defined in the same way as that of the
ManagedExecutorService interface. The following code demon-

Future<String> monitor =
Managed thread factory: The ManagedThreadFactory interface
must implement the java.lang.Runnable interface. The following code
demonstrates how to create and run a container-managed thread.
Thread myThread =
Context service: This interface allows the creation of contextual objects
without using ManagedExecutorService or ManagedScheduledEx-
ecutorService interfaces, as we did in the previous cases, with the aim
of allowing the extension of the capabilities of a Java EE platform for con-

or use customized Java SE platform ExecutorService implementations
within a container. For example, if you desire to use the pool management
