The thread pool created via the admin console is an ORB thread pool that is
meant to be assigned to J2EE connectors/resource adapters [WorkManager] or the
ORB. This cannot be used externally [in a portable fashion] by applications.

The EJB and the servlet specifications explicitly prohibit an application from
create their own threads/thread-pool within the container. The portable
mechanism would be to use the Work Manager Contract in the J2EE connector
specification or handle such work asy.

Quartz integration could also be done via a resource adapter.
