Server did not recognize the value of HTTP Header SOAPAction:

[Harshit Shrivastava]

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();
                
                SOAPBody body = envelop.getBody();
                
                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", dest);
                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());
                
                TransformerFactory transFact = TransformerFactory.newInstance();
                Transformer transformer = transFact.newTransformer();
                Source sourceContent = reply.getSOAPPart().getContent();
                StreamResult res = new StreamResult(System.out);
                transformer.transform(sourceContent, res);
                
                conn.close();
            }
            catch(Exception e)
            {
                System.out.println(e.getMessage());
            }
            
            
        }
        
    }

Result

 add(10,20) = soap:Client

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;  
        }  
    }

Returned XML

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
      <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">

BUILD SUCCESSFUL (total time: 1 second)

Why java program is printing unexpected result i.e. `soap:Client` ?

I'm not familiar with C# WS, but I would expect the SOAPAction header to indicate which operation should be carried out, like "AddProg".

You might want to ask this in a .Net forum, since it's a server-side issue.
