[AXIS2] SOAP Action is not set by service Client when its invoked via a WSDL

[keith chapman <ke...@gmail.com>]

Hi devs,

I was trying accessing an external webservice using service client as
follows,

        ServiceClient serviceClient = new ServiceClient(null, new URL("
http://www.webservicex.net/CurrencyConvertor.asmx?wsdl"), new QName("
http://www.webserviceX.NET/","CurrencyConvertor"), "CurrencyConvertorSoap");
        StAXOMBuilder stAXOMBuilder = new StAXOMBuilder(new
ByteArrayInputStream(

"<ConversionRate><FromCurrency>USD</FromCurrency><ToCurrency>LKR</ToCurrency></ConversionRate>".getBytes()));
        OMElement omElement = serviceClient.sendReceive(
                new QName("http://www.webserviceX.NET/", "ConversionRate"),
stAXOMBuilder.getDocumentElement());
        System.out.println(omElement.toString());

But this call was failing with the exception
"System.Web.Services.Protocols.SoapException: Server did not recognize the
value of HTTP Header SOAPAction: ."

The request sent by the client had the header SOAPAction: "" whereas the
WSDL had <soap:operation soapAction="
http://www.webserviceX.NET/ConversionRate" style="document"/>

debugging through I noticed the following lines in
WSDL11ToAxisServiceBuilder (Line 2340)

                    if (isServerSide) {

axisBindingOperation.getAxisOperation().setSoapAction(soapActionURI);

                    }
                    else {

axisBindingOperation.getAxisOperation().setOutputAction(soapActionURI);
                    }

and CommonsHTTPTransportSender has the following in line 200

soapActionString = messageContext.getAxisOperation()
                            .getSoapAction();

Now this looks like a bug to me. Does anybody have a clue as to why we dont
set the soapAction on the axisoperation when the axisService is on the
client side?

Thanks,
Keith.

Hi Keith.
Yes, it's to do with WS-Addressing where there are both input and
output actions. In that case, the client 'output action' is the action
you should put on the request message.
There's been a lot of misunderstandings about this resulting in lots
of changes over the years such that I'm not 100% convinced it's
correct right now. (There should be a distinction in the code between
input actions and the soap action, and at one point there was, but
last time I looked it appeared to have gone).
I'll take another look and try to work out what's going on.
