Interceptor used by the SCA Binding on the service side chain to provide a mechanism for optimising invocations when the reference and the service involved are both in the same JVM, and thus the need to use a transport of any kind is unnecessary.
     private static final Logger logger = Logger.getLogger(SCABindingLocalInvocationInterceptor.class.getName());
     private Invoker next;
 	private boolean skipPrevious;    
     } // end constructor
     public Message invoke(Message msg) {
         return .invoke(msg);
     } // end method invoke   
     public Invoker getNext() {
         return ;
     } // end method getNext
     public void setNext(Invoker next) {
         this. = next;
     } // end method setNext
Process request method is simply a passthrough
 	public Message processRequest(Message msg) {
 		return msg ;
 	} // end method processRequest

Handle an async response - deals with the local SCA binding case only (at present) - in this case, extract the async response invoker from the message header and call the EPR that is present in the invoker, which is in fact the local EPR from which the original forward request came
     public void invokeAsyncResponse(Message msg) {
 		AsyncResponseInvoker<?> respInvoker = 
         ifrespInvoker != null && "SCA_LOCAL".equals(respInvoker.getBindingType()) ) {
         	// Handle the locally optimised case
 	        RuntimeEndpointReference responseEPR = (RuntimeEndpointReference)respInvoker.getResponseTargetAddress();
 	        // Handle async response Relates_To message ID value
         	String msgID = respInvoker.getRelatesToMsgID();
 	        // Call the processing on the reference chain directly
 	        // Prevent the response being processed by the rest of the service chain
         } else {
         	// Carry on processing the response by the rest of the service chain
             InvokerAsyncResponse thePrevious = (InvokerAsyncResponse)getPrevious();
             if (thePrevious != null ) thePrevious.invokeAsyncResponse(msg);
         } // end if
     } // end method invokeAsyncResponse
processResponse is not called during async response handling (all handled by invokeAsyncResponse) - this version is a dummy which does nothing.
		return msg;
// end method processResponse
// end class
