 The CommonJ API enables concurrent programming of EJBs and
 Servlets within a J2EE application. This API is also known
 as Timer and Work Manager API.
 .
 The CommonJ API contains the following components:
  - Timer API:
    The Timer API allows applications to schedule and receive
    timer notification callbacks for a specific listener defined
    within an application. Timers allow you to schedule and
    perform work at specific times or intervals.
  - Work Manager API:
    The Work Manager API allows an application to prioritize
    work within an EJB or Servlet. Applications can
    programmatically execute multiple work items within a
    container.
