A default servant is a single servant object that provides the implementation for many CORBA objects. In a sense, it is an extension of the concept of a service object (see the section “POA for Service Objects”). However, it is implemented using a different set of POA policies and does not require an active object map.

The following list gives some typical uses for a default servant:
