java - 在 .NET 中使用 Java Web 服务

Question

我正在致力于将 .NET 应用程序与名为 Hermes2 (H2O) 的基于 Servlet 的 Java 应用程序相集成。 Java 应用程序公开了多个 Web 服务，我正在尝试在 Visual Studio 2008 中创建对这些服务的 Web 引用。但这只会导致一个空代理，并附有错误消息:“CODEGEN:操作绑定(bind)‘请求’来自命名空间‘ http://service.ebms.edi.cecid.hku.hk/ ' 被忽略。不支持为 use=literal 消息指定类型。"。

当我尝试通过 .NET 中的 wsdl.exe 实用程序运行 WSDL 时，我得到以下输出:

Microsoft (R) Web Services Description Language Utility
[Microsoft (R) .NET Framework, Version 2.0.50727.42]
Copyright (C) Microsoft Corporation. All rights reserved.
Warning: This web reference does not conform to WS-I Basic Profile v1.1.
R2204: A document-literal binding in a DESCRIPTION MUST refer, in each of its soapbind:body element(s), only to wsdl:part element(s) that have been defined using the element attribute. 
-  Part 'messageId' of message 'EbmsRequestMsg' from service description with targetNamespace='http://service.ebms.edi.cecid.hku.hk/'.
-  Part 'hasMessage' of message 'EbmsResponseMsg' from service description with targetNamespace='http://service.ebms.edi.cecid.hku.hk/'.

Writing file 'C:\Files\Temp\Helsekortet\Hermes\wsdl\EbmsMessageReceiverDownload.cs'.

有谁知道问题出在哪里，以及如何解决？我假设 Hermes2 使用某种通用的 Web 服务库。是否有任何此类 Java 库会生成无效的 WSDL，或者这仅仅是 .NET 不支持的某些功能？

WSDL 如下(我在这里看不到任何附加文件的方式，而且我没有 WSDL 的 URL。抱歉发布了一个臃肿的问题):

希望大家帮忙。

<message name="EbmsRequestMsg">
  <part name="messageId" type="s:string" /> 
</message>
<message name="EbmsResponseMsg">
  <part name="hasMessage" type="s:string" /> 

这些必须引用元素声明而不是原始的简单类型。您需要创建一个包含字符串简单类型的元素包装器。
