WebService InvocationTargetException

/ 16 марта 2020

У меня есть 2 SOAP приложения веб-службы - Потребитель и Производитель, оба выполняются в отдельных экземплярах Wildfly на моей Ma c.

  • Wildfly с источником работает в контейнере docker.
  • Wildfly с потребителем работает в экземпляре wildfly
    , работающем на моей маме c.

Теперь, когда Потребитель звонит через веб-службу, я сталкиваюсь со следующим исключением 

java.lang.reflect.InvocationTargetException: null

Проблема возникает: - 

Caused by: org.apache.cxf.binding.soap.SoapFault: Fault occurred while processing.

Вышеприведенная трассировка стека основана на регистрации переменной stackTraceAsString - фрагмент кода ниже

Однако, не так много, чтобы дать представление о причине сбоя.

Я могу успешно вызвать веб-сервис Producer через SoapUI, работающий на моем Ma c.

. Я проверил URL-адрес конечной точки, настроенный для Consumer. Это то же самое, что и SoapUI.

Будем благодарны за любые предложения, чтобы понять причину и решение.

Заранее спасибо.

Пит

фрагмент кода 

// get the web service operation to invoke for this request type.
final String webServiceOperation = getRequestOperation();

final Class<ProducerWebServiceInterface> clientProducerWebServiceInterface = ProducerWebServiceInterface.class;

// get the appropriate web service method to invoke
Method method = null;
WebServiceResponse serviceResponse = null;

try {

    method = clientProducerWebServiceInterface.getMethod(webServiceOperation, type);

    serviceResponse = (WebServiceResponse) method.invoke(client, operation);

}

catch (final SecurityException | NoSuchMethodException | IllegalArgumentException | IllegalAccessException exception) {

        logError ( exception );

}
catch ( final Exception exception ) {

    StringWriter stringWriter = new StringWriter();
    PrintWriter printWriter = new PrintWriter(stringWriter);
    exception.printStackTrace(printWriter);
    String stackTraceAsString = stringWriter.toString();

        logError ( exception );

}

Кажется строка кода

return invoke0 (method, obj, args);

in класс NativeMethodAccessorImpl создает исключение InvocationTargetException, но все еще не знает, в чем причина. Params - метод, obj, args - все выглядит хорошо. Я определил это, установив точку прерывания в eclipse для прерывания в вхождении InvocationTargetException. 

class NativeMethodAccessorImpl extends MethodAccessorImpl {
    private final Method method;
    private DelegatingMethodAccessorImpl parent;
    private int numInvocations;

    NativeMethodAccessorImpl(Method method) {
        this.method = method;
    }

    public Object invoke(Object obj, Object[] args)
        throws IllegalArgumentException, InvocationTargetException
    {
        // We can't inflate methods belonging to vm-anonymous classes because
        // that kind of class can't be referred to by name, hence can't be
        // found from the generated bytecode.
        if (++numInvocations > ReflectionFactory.inflationThreshold()
                && !ReflectUtil.isVMAnonymousClass(method.getDeclaringClass())) {
            MethodAccessorImpl acc = (MethodAccessorImpl)
                new MethodAccessorGenerator().
                    generateMethod(method.getDeclaringClass(),
                                   method.getName(),
                                   method.getParameterTypes(),
                                   method.getReturnType(),
                                   method.getExceptionTypes(),
                                   method.getModifiers());
            parent.setDelegate(acc);
        }

        return invoke0(method, obj, args);
