从 C# 问题访问 JAX-WS webservice

Question

我必须在 VPN 网络中使用 SOAP 网络服务（所以你无法测试它），用 Java 编写（JAX-WS 网络服务） . 我在服务器端没有访问权限。当我尝试从 C# 4.0 客户端调用 Web 方法时出现此异常：

  The CustomBinding on the ServiceEndpoint with contract 'ServicesSoap' lacks a TransportBindingElement.  Every binding must have at least one binding element that derives from TransportBindingElement.
at System.ServiceModel.Channels.Binding.EnsureInvariants(String contractName)
   at System.ServiceModel.Channels.ServiceChannelFactory.BuildChannelFactory(ServiceEndpoint serviceEndpoint, Boolean useActiveAutoClose)
   at System.ServiceModel.ChannelFactory.CreateFactory()
   at System.ServiceModel.ChannelFactory.OnOpening()
   at System.ServiceModel.Channels.CommunicationObject.Open(TimeSpan timeout)
   at System.ServiceModel.ChannelFactory.EnsureOpened()
   at System.ServiceModel.ChannelFactory`1.CreateChannel(EndpointAddress address, Uri via)
   at System.ServiceModel.ClientBase`1.CreateChannel()
   at System.ServiceModel.ClientBase`1.CreateChannelInternal()
   at System.ServiceModel.ClientBase`1.get_Channel()
   at GatewayClient.Lotto.ServicesSoapClient.GatewayClient.Lotto.ServicesSoap.InfoRequest(InfoRequestRequest request)
   at GatewayClient.Lotto.ServicesSoapClient.InfoRequest(infoDataIn request)
   at GatewayClient.MainWindow.InfoRequestButton_Click(Object sender, RoutedEventArgs e)

这是我的 app.config:

   <system.serviceModel>
    <bindings>
        <customBinding>
            <binding name="ServicesSoapPortBinding">
                <textMessageEncoding messageVersion="Soap12" />
            </binding>
        </customBinding>
    </bindings>
    <client>
        <endpoint address="http://xxx.yyy/Services"
            binding="customBinding" bindingConfiguration="ServicesSoapPortBinding"
            contract="ServiceReference1.ServicesSoap" name="ServicesSoapPort" />
    </client>
</system.serviceModel>

有什么帮助吗？

我已经解决了在 binding 标签中添加 httpTransport 的问题，在 app.config:

<binding name="ServicesSoapPortBinding">
    <textMessageEncoding messageVersion="Soap12" />
    <httpTransport/>
</binding>

我必须在 Visual Studio "Service References" 功能中添加服务参考。尝试使用 svcutil，我得到另一个不同的异常。
