AddressingDispositionException

com.sun.corba.se.impl.protocol.AddressingDispositionException

AddressingDispositionException is described in the javadoc comments as:

This exception is thrown while reading GIOP 1.2 Request, LocateRequest to indicate that a TargetAddress disposition is unacceptable. If this exception is caught explicitly, this need to be rethrown. This is eventually handled within RequestPRocessor and an appropriate reply is sent back to the client. GIOP 1.2 allows three dispositions : KeyAddr (ObjectKey), ProfileAddr (ior profile), IORAddressingInfo (IOR). If the ORB does not support the disposition contained in the GIOP Request / LocateRequest 1.2 message, then it sends a Reply / LocateReply indicating the correct disposition, which the client ORB shall use to transparently retry the request with the correct disposition.
