How to call a c# web service in java?

Question

I have made a java application which calls the C# web service. Here is the code.

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());
        }


    }

}

Error

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

Expected Result

add(10,20) = 30

c# webservice code

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

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

What is wrong with the headers ?

Answer 1

The soapAction you specify in your java code headers.addHeader("SOAPAction", "http://localhost:1267/WebService1.asmx"); should correspond to the soapAction specified for the operation you're targeting, that is http://tempuri.org/HelloWorld or http://tempuri.org/Addweb.
