SendingContext.RunTime interface.
 A sending context may be either the client side or the server side of an invocation, depending on which contains a value type. The sending context is the client side of an invocation if the request contains a value type. It is the server side if the reply contains a value type. The other party in the communication is the receiving context.
 The service context marshalled for SendingContext
 consists of an encapsulated IOR for the SendingContext.RunTime
 interface.  RunTime is just a marker
 interface defined to allow extensibility in the future.  There is
 currently only one subinterface of RunTime defined:
 the SendingContext.CodeBase interface.
 The interface CodeBase defines operations to obtain code URLs
 and meta-information about a value type received from the sending
 context.
 
 Note that these classes are currently defined in the
 com.sun.org.omg.SendingContext
 package rather than in the package org.omg.SendingContext.
 This has been done to avoid including large parts of the interface
 repository in the JDK core, since the interface repository is still
 evolving in response to the needs of the CORBA Components work.

support in Java[tm] SE 6.
