Come chiamare un servizio web C# in java?

Question

Ho creato un'applicazione java che chiama il servizio web C#. Ecco il codice.

package callwebserviceadd; 

import java.util.Iterator; 
import javax.xml.soap.*; 
import javax.xml.transform.*; 
import javax.xml.transform.stream.StreamResult; 

import org.w3c.dom.Node; 

public class CallWebServiceAdd { 

public static void main(String[] args) { 
     // TODO code application logic here 
     String a = "10"; 
    String b = "20"; 

    String op = "Addweb"; 
    String urn = "WebService1"; 
    String dest = "http://localhost:1267/WebService1.asmx"; 

    try 
    { 
     SOAPConnectionFactory soapConnFact = SOAPConnectionFactory.newInstance(); 
     SOAPConnection conn = soapConnFact.createConnection(); 

     MessageFactory msgFact = MessageFactory.newInstance(); 
     SOAPMessage msg = msgFact.createMessage(); 

     SOAPPart soapPart = msg.getSOAPPart(); 
     SOAPEnvelope envelop = soapPart.getEnvelope(); 
     envelop.addNamespaceDeclaration("xsd", "http://www.w3.org/2001/XMLSchema"); 
     SOAPBody body = envelop.getBody(); 

     QName bodyName = new QName("http://localhost:1267/","Addweb");    
     SOAPElement bodyElement = body.addBodyElement(bodyName); 
     QName name = new QName("A"); 
     SOAPElement symbol = bodyElement.addChildElement(name); 
     symbol.addTextNode(a); 
     /*SOAPElement bodyelement = body.addChildElement("Addition"); 
     SOAPElement bodyelement1 = bodyelement.addChildElement("a").addTextNode(a); 
     SOAPElement bodyelement2 = bodyelement.addChildElement("b").addTextNode(b); 
     */ 
     MimeHeaders headers = msg.getMimeHeaders(); 
     headers.addHeader("SOAPAction", "http://localhost:1267/WebService1.asmx"); 
     //msg.writeTo(System.out); 
     msg.saveChanges(); 

     SOAPMessage reply = conn.call(msg, dest); 

     soapPart = reply.getSOAPPart(); 
     envelop = soapPart.getEnvelope(); 
     body = envelop.getBody(); 

     Iterator iter = body.getChildElements(); 
     Node resultOuter = ((Node)iter.next()).getFirstChild(); 
     Node result = resultOuter.getFirstChild(); 

     System.out.println("add(" + a + ","+ b + ") = " + result.getNodeValue()); 
     reply.writeTo(System.out); 

     conn.close(); 
     } 
     catch(Exception e) 
     { 
      System.out.println(e.getMessage()); 
     } 


    } 

} 

errore

Server did not recognize the value of HTTP Header SOAPAction: http://localhost:1267/WebService1.asmx 

Risultato atteso

add(10,20) = 30 

codice C# webservice

public class WebService1: System.Web.Services.WebService 
{   

    [WebMethod] 
    public int AddProg(int a, int b) 
    { 
     return a + b; 
    } 
}

Cosa c'è di sbagliato con le intestazioni?

Answer 1

Il soapAction si specifica nel codice Java headers.addHeader("SOAPAction", "http://localhost:1267/WebService1.asmx"); deve corrispondere al soapAction specificato per l'operazione che stai targeting, cioè http://tempuri.org/HelloWorld o http://tempuri.org/Addweb.

Answer 2

Il valore dell'intestazione SOAPAction è errato. Il valore corretto deve essere indicato nel WSDL per ogni operazione. Ad esempio http://tempuri.org/HelloWorld per l'operazione HelloWorld

<wsdl:operation name="HelloWorld"> 
<soap:operation soapAction="http://tempuri.org/HelloWorld" style="document" /> 
<wsdl:input> 

o http://tempuri.org/Addweb per l'operazione Addweb
