Я пытаюсь запустить веб-службу на основе ее owls
файла описания, используя owls-api -3.1а>.
Веб-служба представляет собой простой jax-ws, развернутый с помощью grizzly, файл owls сгенерированный с использованием класса WSDL2OWLS
из примеров кода (загруженных и извлеченных из jar-файла src
), код размещен в этой версии репозиторий github.
(веб-сервис хорошо протестирован с использованием soapUI
)
Определение веб-службы
@WebService(serviceName = "Hello", targetNamespace = HelloService.WSDL_FILE)
public class HelloService {
public static final String ROUTE = "/hello";
public static final String OWLS_FILE = Bootstrap.OWLS_DIR + "/hello.owl";
public static final String WSDL_FILE = "HTTP://127.0.0.1/hello?wsdl";
/**
* This is a sample web service operation
*
* @param name
* @return
*/
@WebMethod(operationName = "hello")
public String hello(@WebParam(name = "name") String name) {
return "Hello " + name;
}
}
Развертывание веб-сервиса
HttpServer httpServer = new HttpServer();
NetworkListener networkListener = new NetworkListener("grizzly", "0.0.0.0", 8080);
httpServer.addListener(networkListener);
httpServer.getServerConfiguration().addHttpHandler(new CLStaticHttpHandler(Bootstrap.class.getClassLoader(), "static/"), "/");
httpServer.getServerConfiguration().addHttpHandler(new JaxwsHandler(new HelloService()), HelloService.ROUTE);
httpServer.start();
Thread.sleep(2 * 1000); // The services are up and running
System.out.println(" --- OWLS client --- ");
new HelloServiceOWLSClient().start();
Thread.currentThread().join();
клиент OWLS
public class HelloServiceOWLSClient {
private static final Logger LOG = Logger.getLogger(HelloServiceOWLSClient.class.getName());
public void start() {
try {
OWLKnowledgeBase kb = OWLFactory.createKB();
Service service = kb.readService(URI.create(HelloService.OWLS_FILE));
Process process = service.getProcess();
ProcessExecutionEngine executionEngine = OWLSFactory.createExecutionEngine();
ValueMap<Input, OWLValue> inputs = new ValueMap<>();
inputs.setValue(process.getInput("name"), kb.createDataValue("tarrsalah"));
LOG.log(Level.INFO, inputs.debugString());
ValueMap<Output, OWLValue> outputs = executionEngine.execute(process, inputs, kb);
LOG.log(Level.INFO, outputs.debugString());
} catch (IOException | ExecutionException ex) {
LOG.log(Level.SEVERE, ex.toString());
} finally {
}
}
}
