<DD>Returns the instance associated with the requested name, which may be in a atomic or composite form. Atomic (i.e.
 leaf) contexts will return an instance associated with the service name part of the compound name, which may be
 null.
 <p/>
 Composite contexts will return an instance (likely a proxy) of a contained entry point context. In this case, the
 port name on the qualified name will correspond to the composite context name and the part name will be used to
 retrieve the contained entry point context. The latter may be null. If the contained context is not an entry
 point context, an exception will be thrown.
