In JacORBSubsystemAdd:

CorbaORBService orbService = new CorbaORBService(props);
final ServiceBuilder<ORB> builder = context.getServiceTarget().addService(
CorbaORBService.SERVICE_NAME, orbService);
// inject the socket bindings that specify the JacORB IIOP and IIOP/SSL ports.
builder.addDependency(SocketBinding.JBOSS_BINDING_NAME.append(JACORB_SOCKET_BINDING), SocketBinding.class,
orbService.getJacORBSocketBindingInjector());
builder.addDependency(SocketBinding.JBOSS_BINDING_NAME.append(JACORB_SSL_SOCKET_BINDING), SocketBinding.class,
orbService.getJacORBSSLSocketBindingInjector());

The JACORB_SOCKET_BINDING and JACORB_SSL_SOCKET_BINDING values should be coming from some configuration attributes, which perhaps have those constants as their default values. Users can name socket-binding configs whatever they want; the names we provide in our standard configs are just obvious defaults.
