Hi,
I am calling a webservice from pl/sql.
The wsdl is :-
http://imaging.us.oracle.com:16000/axf-ws/AxfSolutionMediatorService?wsdl

The constructed XML is as :-
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/1999/XMLSchema-instance" xmlns:xsd="http://www.w3.org/1999/XMLSchema">
       <SOAP-ENV:Header>
               <Security xmlns="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd">
                           <UsernameToken> 
                                         <Username>XXXXXX</Username> 
                                         <Password>XXXXXX</Password> 
                           </UsernameToken> 
                </Security>
         </SOAP-ENV:Header>
          <SOAP-ENV:Body>
                  <execute xmlns="http://imaging.us.oracle.com:16000/axf-ws/AxfSolutionMediatorService" SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
                              <SolutionNamespace xsi:type="partns:string">Invoice</SolutionNamespace>
                              <CommandNamespace xsi:type="partns:string">StartInvoice</CommandNamespace>
                              <username xsi:type="partns:string">XXXXXX</username>
                  </execute>
           </SOAP-ENV:Body>
</SOAP-ENV:Envelope>



I am new to XML. The created XML throws the below error when I try to check for faults in XML.
ORA-20000: ns2:Client - Cannot find dispatch method for {http://imaging.us.oracle.com:16000/axf-ws/AxfSolutionMediatorService}execute
ORA-06512: at "SCOTT.SOAP_API", line 250
ORA-06512: at "SCOTT.SOAP_API", line 299
ORA-06512: at "SCOTT.PKG_MY_WEBSERVICE", line 42
ORA-06512: at line 4



Please suggest as where I ma going wrong and what value I need to put for the method. Please have a look at the WSDL and suggest.

Thanks for looking into this,
Mahi

ORA-20000 is a custom message from the application,
you have to call the application (webservice) support to get the answer.

I am printing the xml output when there is an error/fault which is as below:-
<?xml version='1.0' encoding='UTF-8'?><S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/"><S:Body><ns2:Fault xmlns:ns2="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns3="http://www.w3.org/2003/05/soap-envelope"><faultcode>ns2:Client</faultcode><faultstring>
Cannot find dispatch method for {http://imaging.us.oracle.com:16000/axf-ws/AxfSolutionMediatorService}execute</faultstring></ns2:Fault></S:Body></S:Envelope>


Not sure where and how to pass the method which after looking at WSDL seems to be 'execute' as method.

WSDL :-
This XML file does not appear to have any style information associated with it. The document tree is shown below.

This is first time I am using XML. So please bear with me for my ignorance.

I have got the link http://imaging.us.oracle.com:16000/axf-ws/AxfSolutionMediatorService by client. I was supposed to see the WSDL & xsd and do the thing. So do you think I am not wrong anywhere for the error I am getting :-

Cannot find dispatch method for {http://imaging.us.oracle.com:16000/axf-ws/AxfSolutionMediatorService}execute


I have tried a lot but still getting the error for the method 'execute'. Can you please give some guideline... when I can't ask questions to client when I am not sure what exactly to ask Sad

Still the same answer.
Did you call the aplication support?
He is the ONLY one that can answer you, it is HIS message.
It is NOT an Oracle RDBMS message.

I am using the package SOAP_API from www.oracle-base.com/dba/miscellaneous/soap_api.sql. And the messages are handled in the below procedure from the above package...

PROCEDURE check_fault(p_response IN OUT NOCOPY  t_response) AS
-- ---------------------------------------------------------------------
  l_fault_node    XMLTYPE;
  l_fault_code    VARCHAR2(256);
  l_fault_string  VARCHAR2(32767);
BEGIN
  l_fault_node := p_response.doc.extract('/'||p_response.envelope_tag||':Fault',
                                         'xmlns:'||p_response.envelope_tag||'="http://schemas.xmlsoap.org/soap/envelope/');
                                         
  IF (l_fault_node IS NOT NULL) THEN
     dbms_output.put_line('l_fault_node IS NOT NULL...');
    l_fault_code   := l_fault_node.extract('/'||p_response.envelope_tag||':Fault/faultcode/child::text()',
                                           'xmlns:'||p_response.envelope_tag||'="http://schemas.xmlsoap.org/soap/envelope/').getstringval();
    l_fault_string := l_fault_node.extract('/'||p_response.envelope_tag||':Fault/faultstring/child::text()',
                                           'xmlns:'||p_response.envelope_tag||'="http://schemas.xmlsoap.org/soap/envelope/').getstringval();
    RAISE_APPLICATION_ERROR(-20000, l_fault_code || ' - ' || l_fault_string);
  END IF;
END;


Not sure whom should I call Sad

It is more a SOAP question. Maybe the following article will help you:

The links didn't helped. I am working on calling an authenticated webservices with username/password from pl/sql using the Soap_Api package
