When using Oracle Data Integrator (ODI) 12c to make web service calls to a WSDL endpoint, ODI adds an unexpected "?WSDL" to the end of the URL, causing the URL to become invalid. This can cause the request to fail, and an error logged to the remote server.

The WSDL for this third-party web service API has a pattern similar to the following:


When ODI sends the request, it sends the following, which contains two question mark (?) query indicators:


This request fails, due to the invalid URL structure, and can raise alerts on the remote endpoint server.

Locally, the Studio or Agent log may show the following:

Error reaching WSDL with appending'?WSDL' https://<HOSTNAME>:<PORT>/<PATH_TO_ACTION>/Wsdl.action?wsdl=<REMOTE_ACTION>?WSDL[[
com.sunopsis.wsinvocation.SnpsWSInvocationException: This URL does not point to a valid WSDL

However, ODI makes a second request after the failure that does not include the "?WSDL" and it is successful.
