Subject WSIF - Method Not Found, Calling .Net Webservice
Date Wed, 07 Jan 2004 06:16:40 GMT
Hi there.
I am trying to invoke a .Net webservice using WSIF but encountered a "Method 
was not found" error below:
=============================================================
F:\Apache\wsif-2.0>java org.tempuri.Run
- WSIF0006W: Multiple WSIFProvider found supporting the same namespace URI 
'http://schemas.xmlsoap.org/wsdl/soap/'. Found 
('org.apache.wsif.providers.soap.apacheaxis.WSIFDynamicProvider_ApacheAxis, 
org.apache.wsif.providers.soap.apachesoap.WSIFDynamicProvider_ApacheSOAP')
- WSIF0007I: Using WSIFProvider 
'org.apache.wsif.providers.soap.apacheaxis.WSIFDynamicProvider_ApacheAxis' 
for namespaceURI 'http://schemas.xmlsoap.org/wsdl/soap/'
Error while executing sample, received an exception from WSIF; details:
org.apache.wsif.WSIFException: Method getServiceDtls(class java.lang.String) 
was not found in portType {http://tempuri.org/}ServiceSoap
        at 
org.apache.wsif.base.WSIFClientProxy.findMatchingOperation(Unknown Source)
        at org.apache.wsif.base.WSIFClientProxy.invoke(Unknown Source)
        at $Proxy0.getServiceDtls(Unknown Source)
        at org.tempuri.Run.main(Run.java:52)
=============================================================

Not sure if you could help but to give you some background, I have extracted 
some code from my application in the sections below.

My Run.java is written similar to the SimpleSoap.java sample in the WSIF 
website as follows:
=============================================================
package org.tempuri;

import org.apache.wsif.WSIFService;
import org.apache.wsif.WSIFServiceFactory;
import org.apache.wsif.WSIFException;
import java.rmi.RemoteException;

import org.tempuri.ServiceSoap;

public class Run {

    public static void main(String[] args) {
        try {

            // create a service factory
            WSIFServiceFactory factory = WSIFServiceFactory.newInstance();

            // parse WSDL
            WSIFService service =
	 factory.getService(					    
"http://ma4is_win2003/niftyws/service.asmx?WSDL",
	    null,
	    null,
	    "http://tempuri.org/",
	    "ServiceSoap");

            // create the stub
            ServiceSoap stub =
                    (ServiceSoap) service.getStub(
                        ServiceSoap.class);

            // do the invocation
            ServiceDtlsResult ret = stub.getServiceDtls("91234567");

} catch (WSIFException we) {
            System.out.println(
                "Error while executing sample, received an exception from 
WSIF; details:");
            we.printStackTrace();
        } catch (RemoteException re) {
            System.out.println(
                "Error while executing sample, received an exception due to 
remote invocation; details:");
            re.printStackTrace();
        }
}
=============================================================

The interface file ServiceSoap.java generated by Axis WSDL2Java is as 
follows:
=============================================================
/**
* ServiceSoap.java
*
* This file was auto-generated from WSDL
* by the Apache Axis WSDL2Java emitter.
*/

package org.tempuri;

public interface ServiceSoap extends java.rmi.Remote {
    public org.tempuri.ServiceDtlsResult getServiceDtls(java.lang.String 
sService) throws java.rmi.RemoteException;
    public org.tempuri.ServiceComponentResult 
getServiceComponents(java.lang.String sService) throws 
java.rmi.RemoteException;
    public org.tempuri.StandardStringResult 
validateCustIdNDOBWithService(java.lang.String sService, java.lang.String 
sCustID, java.lang.String sCustIDType, java.lang.String sDOB) throws 
java.rmi.RemoteException;
}
=============================================================

The webservice's sample SOAP request is as follows:
=============================================================
POST /niftyws/service.asmx HTTP/1.1
Host: ma4is_win2003
Content-Type: text/xml; charset=utf-8
Content-Length: length
SOAPAction: "http://tempuri.org/GetServiceDtls"

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xmlns:xsd="http://www.w3.org/2001/XMLSchema" 
xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
  <soap:Body>
    <GetServiceDtls xmlns="http://tempuri.org/">
      <sService>string</sService>
    </GetServiceDtls>
  </soap:Body>
</soap:Envelope>
=============================================================

A discrepancy I see is that the first letter for the method 
getServiceDtls(class java.lang.String), i.e. 'g', is  different from that of 
the tag <GetServiceDtls xmlns="http://tempuri.org/">, i.e. 'G',  in the soap 
request document.
I'm not sure if this is the problem.
Appreciate any advice.

Regards,
Fabian Chew.
