NullServant is used to represent a null servant returned
OAInvocationInfo after a
ObjectAdapter.getInvocationServant( OAInvocationInfo ) call.
If the getInvocationServant call could not locate a servant
for the ObjectId in the OAInvocationInfo, getServantContainer
will contain a NullServant. Later stages of the request
dispatch may choose either to throw the exception or perform
some other action in response to the NullServant result. |
