com.sun.sgs.kernel.TaskScheduler
This interface is used to run tasks that may take an arbitrarily long time to complete, but are expected to complete eventually. These tasks may be scheduled to run immediately or after some delay, possibly re-executing at regular intervals.
Based on an implementation's policy, a task and its owner, that task may not be accepted for execution. In this case {@code TaskRejectedException}is thrown. To ensure that a task will be accepted methods are provided to get a {@code TaskReservation}. This is especially useful for {@code Service}methods working within a transaction that need to ensure that a task will be accepted before they can commit.
Note that, because the tasks submitted through this interface may run any length of time, there are no guarantees about when a given task will start. If a task is scheduled to run immediately, or at some point in the future, then this means that the scheduler will try to acquire resources to run the task at that point. It may still be some indefinite length of time before the task can actually be run.

Abstraction for scheduling a Task
org.springframework.scheduling.TaskScheduler
Task scheduler interface that abstracts the scheduling of {@link Runnable Runnables} based on different kinds of triggers.
This interface is separate from {@link SchedulingTaskExecutor} since itusually represents for a different kind of backend, i.e. a thread pool with different characteristics and capabilities. Implementations may implement both interfaces if they can handle both kinds of execution characteristics.
The 'default' implementation is {@link org.springframework.scheduling.concurrent.ThreadPoolTaskScheduler}, wrapping a native {@link java.util.concurrent.ScheduledExecutorService}and adding extended trigger capabilities.
This interface is roughly equivalent to a JSR-236 ManagedScheduledExecutorService as supported in Java EE 6 environments. However, at the time of the Spring 3.0 release, the JSR-236 interfaces have not been released in official form yet. @author Juergen Hoeller @since 3.0 @see org.springframework.core.task.TaskExecutor @see java.util.concurrent.ScheduledExecutorService @see org.springframework.scheduling.concurrent.ThreadPoolTaskScheduler
