Detailed Description

All the action for a synchronous twoway invocation happen here.

An object of this type is created by TAO::Invocation_Adapter and invokes a method on this class. The method takes care of creating and sending a request, waiting for a reply and demarshalling the reply for the client.

Invocation_Status TAO::Synch_Twoway_Invocation::handle_system_exception (  TAO_InputCDR &  cdr  )  [protected]

Helper method used to handle system exceptions from the remote objects. There has been a unanimous view that this is not the right way to do things. But a need to be compliant is forcing us into this. Note: A location forwarding loop may occur where a client is bounced from the original target to the forwarded target and back if the application is not equipped to handle retries of previously called targets. TAO may be able to help in this case but it ultimately ends up being an application issue.
