| /** |
| * Factory for transport tubes that enables transport pluggability. |
| * |
| * <p> |
| * At runtime, on the client side, JAX-WS (more specifically the default {@link TubelineAssembler} |
| * of JAX-WS client runtime) relies on this factory to create a suitable transport {@link Tube} |
| * that can handle the given {@link EndpointAddress endpoint address}. |
| * |
| * <p> |
| * JAX-WS extensions that provide additional transport support can |
| * extend this class and implement the {@link #doCreate} method. |
| * They are expected to check the scheme of the endpoint address |
| * (and possibly some other settings from bindings), and create |
| * their transport tube implementations accordingly. |
| * For example, |
| * |
| * <pre> |
| * class MyTransportTubeFactoryImpl { |
| * Tube doCreate(...) { |
| * String scheme = address.getURI().getScheme(); |
| * if(scheme.equals("foo")) |
| * return new MyTransport(...); |
| * else |
| * return null; |
| * } |
| * } |
| * </pre> |
| * |
| * <p> |
| * {@link TransportTubeFactory} look-up follows the standard service |
| * discovery mechanism, so you need |
| * {@code META-INF/services/com.sun.xml.internal.ws.api.pipe.TransportTubeFactory}. |
