Server-side implementation of RmiInvocationHandler. An instance of this class exists for each remote object. Automatically created by RmiServiceExporter for non-RMI service implementations.

This is an SPI class, not to be used directly by applications.

Create a new RmiInvocationWrapper for the given object.
Params:
  • wrappedObject – the object to wrap with an RmiInvocationHandler
  • rmiExporter – the RMI exporter to handle the actual invocation

Exposes the exporter's service interface, if any, as target interface.
