SOAP Fault "HTTP POST method only supported by this endpoint"

A CICS auxtrace of the failure shows an inbound request asking for the WSDL itself to be returned. Here is an excerpt from the auxtrace:

 *GET /service?WSDL HTTP/1.1..Acc:*
 * eptimage/gif, image/jpeg, image*
 */pjpeg, image/pjpeg, application*
 */x-ms-application, application/x*

The above request is asking for the WSDL of Web Service 'service' to be sent back in the response. CICS responded with a SOAPFAULT back to the client:

 *HTTP/1.1 405 Method Not Allowed *
 ...
 ...
 *<SOAP-ENV:Envelope xmlns:SOAP-EN*
 *V="http://schemas.xmlsoap.org/so*
 *ap/envelope/"><SOAP-ENV:Body><SO*
 *AP-ENV:Fault xmlns=""><faultcode*
 *>SOAP-ENV:Client</faultcode><fau*
 *ltstring>HTTP POST method only s*
 *upported by this endpoint</fault*
 *string></SOAP-ENV:Fault></SOAP-E*
 *NV:Body></SOAP-ENV:Envelope>    *

If the WSDL file was present within the WSDIR of the PIPELINE then CICS would have created a URIMAP for /service?WSDL and would have returned the requested file. Instead the request matches the URIMAP created for the web service itself (/service). CICS then rejects the request because it uses a GET method instead of POST.

To resolve this you need to do one of the following:

• Place the WSDL file in the WSDIR of the PIPELINE

• Change the client to not request the WSDL file

• Change the client to tolerate the WSDL file not being returned
