Веб-сервис Java от клиента .NET С# - сбой в пространствах имен?

У меня были аналогичные проблемы с доступом к Java WS из клиента .NET. Я не нашел элегантного решения проблемы, но решил ее, изменив исходящие/входящие сообщения SOAP с помощью SoapExtension:

1. Реализуйте атрибут SoapExtensionAttribute следующим образом:

   class SoapExtAttribute : SoapExtensionAttribute
   {
       int priority = 0;
   
       public override Type ExtensionType
       {
           get { return typeof(SoapExt); }
       }
   
       public override int Priority
       {
           get
           {
               return priority;
           }
           set
           {
               priority = value;
           }
       }
   }
   

2. Реализуйте SoapExtension, например:

   class SoapExt : SoapExtension
   {
       private Stream mWireStream = null;
       private Stream mApplicationStream = null;
   
       public override object GetInitializer(Type serviceType)
       {
           return serviceType;
       }
   
       public override object GetInitializer(LogicalMethodInfo methodInfo, SoapExtensionAttribute attribute)
       {
           return (SoapExtAttribute)attr;
       }
   
       public override void Initialize(object initializer)
       {
       }
   
       public override Stream ChainStream(Stream stream)
       {
           mWireStream = stream;
           mApplicationStream = new MemoryStream();
           return mApplicationStream;
       }
   
   
       public override void ProcessMessage(SoapMessage message)
       {
           StreamWriter writer = null;
           bool fIsServer = (message.GetType() == typeof(SoapServerMessage));
           switch (message.Stage)
           {
               case SoapMessageStage.BeforeDeserialize:
                   string resp = new StreamReader(mWireStream).ReadToEnd();
                   StreamWriter w = new StreamWriter(mApplicationStream);
                   w.WriteLine(resp);
                   w.Flush();
                   mApplicationStream.Seek(0, SeekOrigin.Begin);
                   break;
               case SoapMessageStage.AfterSerialize:
                   mApplicationStream.Seek(0, SeekOrigin.Begin);
                   string reqXml = new StreamReader(mApplicationStream).ReadToEnd();
   
                   XmlDocument doc = new XmlDocument();
                   doc.LoadXml(reqXml);
   
                   Modify(doc);
   
                   reqXml = doc.InnerXml;
   
                   mApplicationStream.Seek(0, SeekOrigin.Begin);
                   writer = new StreamWriter(mWireStream);
                   writer.WriteLine(reqXml);
                   writer.Flush();
   
                   XmlDocument d = new XmlDocument();
                   d.LoadXml(reqXml);
                   ServiceManager.RequestSoap = d.LastChild.OuterXml;
                   break;
           }
       }
   
       private void Modify(XmlDocument doc)
       {
           // Change the doc in whatever way you want, e.g. remove/add the prefixes
       }
   }
