Accessing JAX-WS webservice from C# issue

Question

I have to use a SOAP web service in a VPN network (so you couldn't test it), written in Java (JAX-WS webservice). I don't have access at server side. When i try to call a web method from a C# 4.0 client I get this exception:

  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 GatewayClient.Lotto.ServicesSoapClient.InfoRequest(infoDataIn request)
   at GatewayClient.MainWindow.InfoRequestButton_Click(Object sender, RoutedEventArgs e)

This is my 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>

Any help?

Answer 1

I've solved the issue adding httpTransport in the binding tag, in the app.config:

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

I have to add the service reference within Visual Studio "Service References" feature. Trying to use svcutil, I get another different exception.
