Вы можете использовать мое старое универсальное решение, , но никогда не делайте этого в реальном проекте , это не кросс-язык (это только для решения java client + java server).SerializableAdapler.java может маршалировать и демаршалировать любой объект Java.Для маршалинга он сериализует Java-объект в String, а затем кодирует его в Base64.Для демаршалинга он декодирует строку base64 и десериализует ее для получения объекта Java.Кстати, в этом решении вам нужны помощники (SerializableAdapler.java, Base64Coder.java) как на стороне сервера, так и на стороне клиента.В обычном решении вам нужен только один интерфейс, например SomeService.java на стороне клиента (и SomeService.java, и SomeServiceImpl.java на стороне сервера).Я протестировал его с http://cxf.apache.org/docs/a-simple-jax-ws-service.html, но вы можете использовать другие фреймворки веб-сервисов.
