RE: Apache SOAP client to MS.NET webservice problem

[Soumen Sarkar]

Hello there,

SOAP specification leaves a lot of holes to achieve program
interoperability -- not as solid as OMG IIOP or Java RMI
or CMIP/SNMP network management protocol. Basically all
these distributed communication protocol follows rigid
on the wire data format:

OMG IIOP  : Common Data Representation(CDR)
Java RMI  : Java Remote Messaging Protocol(JRMP)
CMIP/SNMP : ASN.1 BER (ITU standard X.208/X.209)

I do not see why SOAP could not follow a rigid on the wire
data format(i.e encoding style). Maybe somebody knowledgable
could throw more light in this area.

Anyway I did a search in http://www.google.com/ for
"SOAP interoperability" and got a lot of URLs. You can see
for yourself. The most relevant one to your problem is:

http://www.perfectxml.com/articles/xml/soapguide.asp

Hope this helps.

Soumen Sarkar.

Subject: Apache SOAP client to MS.NET webservice problem

Hi there,
 
I'm trying to deploy a web-service using Microsoft .NET, and using
Apache Soap to make a soap request to the web-service. Here comes the
questions. When a client makes a request, server can understand the
request and process it. But client can't understand the soap message
that server responds. Below are the error message:
 
Caught SOAPException (SOAP-ENV:Client): No Deserializer found to
deserialize a
'http://tempuri.org/:result' using encoding style
'http://schemas.xmlsoap.org/s
oap/encoding/'.
 
I've seen many people ask this question before, and I know it is the
interoperability problem between each SOAP implementations. But I still
can't solve this problem. Below are my client program:
=================
client programe
=================
import java.io.*;
import java.util.*;
import java.net.*;
import org.apache.soap.util.xml.*;
import org.apache.soap.*;
import org.apache.soap.encoding.*;
import org.apache.soap.encoding.soapenc.*;
import org.apache.soap.rpc.*;

public class test1 
{
   public test1()
   {
      try
      {
         
         
         URL rurl = new URL("
http://localhost:2020/math/WebSrv_Math.asmx
<http://localhost:2020/math/WebSrv_Math.asmx> ");
                  
         Call call = new Call ();
         call.setTargetObjectURI (" http://tempuri.org/
<http://tempuri.org/> ");
      
         call.setEncodingStyleURI(Constants.NS_URI_SOAP_ENC);
      
         SOAPMappingRegistry smr = new SOAPMappingRegistry();
         StringDeserializer sd = new StringDeserializer();
    
         smr.mapTypes(Constants.NS_URI_SOAP_ENC,new
QName("","Result"),null,null,sd);
         call.setSOAPMappingRegistry(smr);
         
         Vector params = new Vector ();
         params.addElement (new Parameter("ns1:num1", int.class, new
Integer(4),null));
         params.addElement (new Parameter("ns1:num2", int.class, new
Integer(7),null));
                       
         call.setParams (params);      
      
         Response resp;
 
         try
         {
            call.setMethodName ("Add");
            resp = call.invoke (/* router URL */ rurl, /* actionURI */"
http://tempuri.org/Add <http://tempuri.org/Add> "  );
         }
         catch (SOAPException se)
         {
            System.err.println("Caught 1 SOAPException (" +
            se.getFaultCode() + "): " +
            se.getMessage());
            return;
         }

         if (resp.generatedFault ()) 
         {
            Fault fault = resp.getFault ();
            System.out.println ("Ouch, the call failed: ");
            System.out.println ("  Fault Code   = " + fault.getFaultCode
());  
            System.out.println ("  Fault String = " +
fault.getFaultString ());
         } 
         else 
         {
            Parameter result = resp.getReturnValue ();
            String value=(String)result.getValue();
         }
         // Check the response.
      }catch (Exception ae) {}
   }
   public static void main(String args[])
   {
      test1 t=new test1();
   }
}
And below are the soap message that the web service responds:
===========

===========
Cache-Control: private, max-age=0
Content-Type: text/xml
Content-Length: 389
 
<?xml version="1.0"?>

    <AddResult xmlns=" http://tempuri.org/ <http://tempuri.org/> ">
      <result>11</result>
    </AddResult>
  </soap:Body>
</soap:Envelope>
 
Is there any thing wrong with my code?
 
Thanks
