У меня есть сервер, который выполняет вызов Webservice на внешний сервер. Этот вызов должен выполняться через SSL и с использованием прокси:

Моя доверенная сеть настроена правильно:

trustStore is: /opt/configuration/keystore/truststore.jks
trustStore type is : jks
trustStore provider is : 
init truststore
adding as trusted cert:

Также мое рукопожатие выполняется правильно:

У меня есть ProxySelector, который выбирает прокси для использования:

@Override
public List<Proxy> select(URI uri) {

    if (LOGGER.isDebugEnabled()) {
        LOGGER.debug("select for URL : " + uri);
    }

    if (uri == null) {
        throw new IllegalArgumentException("URI cannot be null.");
    }

    // Get protocol and management configuration for HTTP or HTTPS.
    String protocol = uri.getScheme();
    if (StringUtils.equalsIgnoreCase("http", protocol)
            || StringUtils.equalsIgnoreCase("https", protocol)
            || StringUtils.equalsIgnoreCase("socket", protocol)) {
        LOGGER.debug("Retrieving proxy list...");
        List<Proxy> proxyList = new ArrayList<>();
        for (InnerProxy p : proxies.values()) {

            proxyList.add(p.toProxy());
        }
        LOGGER.debug(proxyList.size() + " configured proxies");
        // Return configured Proxy
        return proxyList;
    }

    /*
     * For others protocols (could be SOCKS or FTP etc.) return the default
     * selector.
     */
    if (defaultSelector != null) {
        return defaultSelector.select(uri);
    } else {
        List<Proxy> proxyList = new ArrayList<>();
        proxyList.add(Proxy.NO_PROXY);
        return proxyList;
    }
}

Но при вызове метода на веб-методе, сгенерированном JAX-WS RI:

/**

 * @param xmlMetadata
 * @param xmlReferencedStandard
 * @return
 *     returns java.lang.String

;

Я получаю 8 запросов на выбор запросов (где я ожидал бы только 1):

Селектор Custom Proxy вызывается 4 раза для реального URL-адреса и 4 раза для сокета.

И в журналах я получил следующее исключение, вызванное HTTP-запросом, инициированным Axis (я использую Axis версии 1.6.2): ​​

Я понятия не имею, почему Axis выполняет эти вызовы и почему у меня есть java.net.ConnectException: соединение отклонено (соединение отказано) исключение...

Похоже, он не использует настроенный прокси-сервер...

Надеюсь, что кто-нибудь сможет мне помочь...

Я нашел следующие строки в моем протоколировании:
