You can extend the interface with a "stub" interface that is
defined as remotable, then have your implementation specify the
stub interface as its service interface.  For example, if there is
an external interface belonging to xyz.com that you can't change,
such as:

  package com.xyz;
  public interface HelloWorldService {

then you could create the interface

  package mypackage;
  import org.oasisopen.sca.annotation.Remotable;
  import com.xyz.HelloWorldService;
  public interface HelloWorldServiceRemotable extends HelloWorldService {

and write your implementation as:

  package mypackage;
  public class MyServiceImpl implements HelloWorldServiceRemotable {
