Tie generation
You must put an interfacing layer between the servant and the ORB code. In the old RMI (JRMP) naming convention, skeleton was the name given to the proxy that was used on the server side between ORB and the object implementation. In the RMI-IIOP convention, the proxy is called a Tie.
You generate the RMI-IIOP tie class at the same time as the stub,
by calling the rmic compiler. These classes are
generated from the compiled Java™ programming
language classes that contain remote object implementations. For example,
the command:
rmic -iiop SampleImpl
generates
the stub _Sample_Stub.class and the tie _Sample_Tie.class.
