服务器上的有效JAX-WS请求参数为NULL

Question

我试图找出JAX-WS在过去几天内的间隔行为。

基本上我有两个不同的SOAP请求从两个不同的客户端生成，我无法对这些请求的创建方式进行任何更改。我仍然需要能够处理这两种类型的请求。

不幸的是，第二个请求的请求参数在服务器上设置为NULL，尽管我在请求中发送时有一个有效值。这意味着服务器无法正确解析此请求。我如何告诉我的JAX-WS服务器正确处理这两个请求？

工作要求

<S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/"> 
    <S:Body> 
     <ns2:getMachine xmlns:ns2="http://machine.soap.webservices.product.company.at/"> 
      <machineId>92623-15853588</machineId> 
     </ns2:getMachine> 
    </S:Body> 
</S:Envelope> 

断请求（参数是在服务器端NULL）。

<S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/"> 
    <S:Body> 
     <getMachine xmlns="http://machine.soap.webservices.product.company.at/"> 
      <machineId>92623-15853588</machineId> 
     </getMachine> 
    </S:Body> 
</S:Envelope> 

我似乎无法找到尽管这个问题似乎很长一段时间（See this 2 year old stackoverflow thread）被称为事实的任何解决这个问题。

为了完成，这里是我的WebService的实现。我试图将目标命名空间直接设置为@WebService和@WebParam注释，但它没有效果。

package at.company.product.webservices.soap.machine; 


import javax.jws.WebMethod; 
import javax.jws.WebParam; 
import javax.jws.WebService; 
import javax.jws.soap.SOAPBinding; 

import at.company.product.core.ProductCorePlugin; 
import at.company.product.core.machine.IMachine; 
import at.company.product.webservices.soap.exceptions.InvalidIdException; 

@WebService 
@SOAPBinding(style = SOAPBinding.Style.RPC) 
public class WSMachineApi { 

    @WebMethod 
    public WSMachine getMachine(@WebParam(name = "machineId") String machineId) throws InvalidIdException{ 
     IMachine machine = getMachineById(machineId); 
     if (machine == null){ 
      throw new InvalidIdException(machineId); 
     } 

     return new WSMachine(getMachineById(machineId)); 
    } 

    private IMachine getMachineById(String id) { 
     return ProductCorePlugin.getDefault().getMachineHallAdmin().getMachineByID(id); 
    } 

}

你可能需要定制SOAPHandler利用的WSDL。示例显示为here。 使用自定义处理程序，您将能够轻松调试此问题。
