Axis IllegalArgumentException，但soap消息正確

Question

我遵循client和server教程來創建簡單的客戶端服務器Calculator Web服務，該服務執行兩個int的簡單添加。我所有的課程都是由Intelliji自動生成的。

當我運行的客戶端，我得到：

AxisFault 
faultCode: {http://schemas.xmlsoap.org/soap/envelope/}Server.generalException 
faultSubcode: 
faultString: Tried to invoke method public int calculator.Calculator.add(int,int) with arguments java.lang.Integer,null. The arguments do not match the signature.; nested exception is: 
    java.lang.IllegalArgumentException 
faultActor: 
faultNode: 
faultDetail: 
    {http://xml.apache.org/axis/}hostname:unknown 

但SOAP請求是正確的：

<?xml version="1.0" encoding="UTF-8"?> 
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> 
    <soapenv:Body> 
     <a xmlns="http://calculator">1</a> 
     <b xmlns="http://calculator">7</b> 
    </soapenv:Body> 
</soapenv:Envelope> 

這裏是我Calculator類：

package calculator; 

import javax.jws.WebMethod; 
import javax.jws.WebService; 

@WebService 
public class Calculator { 

    @WebMethod 
    public int add(int a, int b) { 
     return a + b; 
    } 

} 

的所有代碼由Intelliji內置函數生成，如Generate WSDL from Java Code和Generate Java Code from WSDL。

下面是客戶端測試的代碼：

package calculator; 

import javax.xml.rpc.ServiceException; 
import java.rmi.RemoteException; 

public class Test { 

    public static void main(String[] args) { 

     CalculatorService serviceLocator = new CalculatorServiceLocator(); 

     Calculator_PortType service = null; 
     try { 
      service = serviceLocator.getCalculator(); 
     } catch (ServiceException e) { 
      e.printStackTrace(); 
      throw new RuntimeException("Something went wrong"); 
     } 

     try { 
      int add = service.add(1,7); 
      System.out.println("add: " + add); 

     } catch (RemoteException e) { 
      e.printStackTrace(); 
     } 
    } 
} 

這裏是WSDL：

<?xml version="1.0" encoding="UTF-8"?> 
<wsdl:definitions targetNamespace="http://calculator" xmlns:apachesoap="http://xml.apache.org/xml-soap" xmlns:impl="http://calculator" xmlns:intf="http://calculator" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:wsdlsoap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:xsd="http://www.w3.org/2001/XMLSchema">

     <wsdl:output message="impl:addResponse" name="addResponse"/> 
     </wsdl:operation> 
    </wsdl:portType> 
    <wsdl:binding name="CalculatorSoapBinding" type="impl:Calculator"> 
     <wsdlsoap:binding style="document" transport="http://schemas.xmlsoap.org/soap/http"/> 
     <wsdl:operation name="add"> 
     <wsdlsoap:operation soapAction=""/> 
     <wsdl:input name="addRequest"> 
      <wsdlsoap:body use="literal"/> 
     </wsdl:input> 
     <wsdl:output name="addResponse"> 
      <wsdlsoap:body use="literal"/> 
     </wsdl:output> 
     </wsdl:operation> 
    </wsdl:binding> 
    <wsdl:service name="CalculatorService"> 
     <wsdl:port binding="impl:CalculatorSoapBinding" name="Calculator"> 
     <wsdlsoap:address location="http://localhost:8080/services/Calculator"/> 
     </wsdl:port> 
    </wsdl:service> 
</wsdl:definitions> 

的SOAP請求是正確的。我有一個很好的Hello World示例。一切似乎都對。我沒有更改任何默認設置。

當暴露類（1）並生成WSDL文件（2）時，請確保使用wrapped樣式而不是document。
