Hello,
I am doing some hands-on using the webservice functionality in WMB V6.0. The scenario is as given below:

MQInput Node ==> CreateWSRequest ==> HTTPRequest Node ==> ReformatWSResponse ==> MQOutput Node

1. MQInput node receives an xml as input

Code:

<?xml version="1.0" encoding="UTF-8"?>
<UserInput>
<WSDLOperation>ConversionRate</WSDLOperation>
<WSDLSourceCurrency>USD</WSDLSourceCurrency>
<WSDLTargetCurrency>INR</WSDLTargetCurrency>
</UserInput>

2. CreateWSRequest node creates the HTTP Request Header uisng esql below:

Code:

DECLARE tmp_HTTPPostString CHARACTER;
SET tmp_HTTPPostString = 'FromCurrency=' || InputRoot.XML.UserInput.WSDLSourceCurrency || '&ToCurrency=' || InputRoot.XML.UserInput.WSDLTargetCurrency;
SET Environment.MQMD = InputRoot.MQMD;
SET OutputRoot.HTTPRequestHeader.POST = 'CurrencyConvertor.asmx/ConversionRate';
SET OutputRoot.HTTPRequestHeader.Host = '209.162.186.60';
SET OutputRoot.HTTPRequestHeader."Content-Type" = 'application/x-www-form-urlencoded';
SET OutputRoot.BLOB.BLOB = CAST(tmp_HTTPPostString AS BLOB CCSID InputRoot.MQMD.CodedCharSetId);

3. HTTP Request node has all default options set

The webservice is a public service available on internet at http://www.webservicex.net/CurrencyConvertor.asmx

As per the webservice details given, the expected format for POST message is:

Code:

POST /CurrencyConvertor.asmx/ConversionRate HTTP/1.1
Host: www.webservicex.net
Content-Type: application/x-www-form-urlencoded
Content-Length: length

FromCurrency=string&ToCurrency=string

Following is the trace after HTTPRequest Node:

Code:

)
)

The Response from webservice when converted from BLOB to Char string is :

Code:

<?xml version="1.0" encoding="utf-8"?>..<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<soap:Body>
<soap:Fault>
<faultcode>soap:Client</faultcode>
<faultstring>System.Web.Services.Protocols.SoapException: Server did not recognize the value of HTTP Header SOAPAction: ... at System.Web.Services.Protocols.Soap11ServerProtocolHelper.RouteRequest()
at System.Web.Services.Protocols.SoapServerProtocol.Initialize()
at System.Web.Services.Protocols.ServerProtocolFactory.Create(Type type, HttpContext context, HttpRequest request, HttpResponse response, Boolean& abortProcessing)</faultstring>
<detail />
</soap:Fault>
</soap:Body>
</soap:Envelope>

My question is why is it expecting a SOAPAction when i am requesting for a HTTP-POST request? Is this something related to the web server and not an issue with my code?
Are you aware of any public webservice where i can test my flow using HTTP-POST instead of soap message?

Please let me know..

Thanks

Not sure why you think the SOAPAction HTTP header is not needed... try using SOAPUI/tcpmon against that service and you will see the full input/output requirements including the HTTP Headers...
