Java Web服务方法从C#客户端接收空参数

Question

我正在开发一个Java 6应用服务器,它有一个Web服务,用于接收包含HL7消息的SOAP消息.Java应用程序在Glassfish 3.1上运行.客户端是第三方开发的C#应用​​程序(在Microsoft .net 4.0框架上运行),它将这些SOAP消息发送到Java服务器.

我最初的问题是客户端无法解析服务器生成的WSDL.我已经通过实现自己的自定义WSDL并相应地调整它来解决这个问题.这允许客户端解析WSDL并将SOAP消息发送到我的Java服务器应用程序.

但是,每次在服务器端收到消息时,参数(名为"putXML")都在接收null值.

收到消息时,Glassfish服务器日志显示以下内容:

Received WS-I BP non-conformant Unquoted SoapAction HTTP header: http://MyProject.MyPackage/putHL7Data
Received Message: null

这是我创建并与SOAP Web服务相关联的自定义WSDL:

   </wsdl:service>
</wsdl:definitions>

这是Java Web服务:

@WebService(serviceName = "MyHandler", wsdlLocation = "WEB-INF/wsdl/MyHandler.wsdl")
public class MyHandler {
   @WebMethod(operationName = "putHL7Data")
   public String putHL7Data(@WebParam(name = "putXML") String xml) {
      // Handle message
   }
}

有什么我做错了吗？

如何修复Java Web服务以使其正确接收非null值？

这是客户的问题吗？如果是这样,我是否需要创建某种拦截器？

更新

今天我尝试创建一个使用Java SOAP Web服务的快速C#客户端.以下是代码:

namespace TestSoap
{
    class Program
    {
        static void Main(string[] args)
        {
            ServiceReference1.MyHandlerSoapClient ws = new ServiceReference1.MyHandlerSoapClient();
            string result = ws.putHL7Data("Test");    
            Console.WriteLine("Response: " + result);
            Console.ReadLine();
        }
    }
}

当我运行这个客户端null时,我在期望看到Test字符串时在参数中收到相同的值.此外,我期望result包含一个响应字符串,但它也返回一个null值.

请记住,我无法修改第三方C#客户端应用程序.我可以在Java端做什么吗？

更新2

我最近添加了一个处理程序链类,它捕获并记录原始SOAP消息.客户端发送的消息如下所示:

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <soap:Header/>
  <soap:Body>
    <putHL7Data xmlns="http://MyProject.MyPackage/">
      <putXML>... Encoded XML Here ...</putXML>
    </putHL7Data>
  </soap:Body>
</soap:Envelope>

Answer 1

在被@dlawrence指向正确的方向后,我能够解决我的问题.正如我在问题中提到的,我仍然需要使用自定义构建的wsdl.我只需要对wsdl和Java代码进行一些更改即可解决问题.

这是一个代表我对wsdl的更改的差异:

基本上这是一个三部分修复...
1).我需要elementFormDefault="qualified"从<s:schema>标签中删除该属性.
2).然后我不得不form="qualified"在我的<s:element name="putXML" ...>标签上添加属性.
3).最后,我需要确保我的标签soapAction="http://MyProject.MyPackage/putHL7Data"上有属性<soap:operation>.

如您所见,我所要做的就是将targetNamespace属性添加到我的@WebParam.
